Today I roasted up some Cuba Turquino to a light roast for filter on my newly modified KKTO (with new double sided agitator arm and new insulation) - and I was very impressed with the even nature of the roast and the fact that I managed to shave around ten minutes off my usual roast time

Wouldn't mind getting a thermocouple though to monitor the temperature of the roast as the turbo oven appears to 'stall' mid roast - but thus could just be my imagination - which is why temperature monitoring could be good to observe what is actually going on

Still, can't complain about the results as the coffee came up a treat and drank like a dream in my clever coffee dripper: 35g of coffee to 300ml of water steeped for four minutes - now that's what I'm talking about!

The Cricket is going belly up and I thought it was a good time for a roast

Had some small amounts of beans so decided to do a combo roast

300 Grams of PNG Kinjibi AA
300 Grams of Brazil Alterosa RFA
280 Grams of Peru  Ceja de Selva Estate
Total roast weight = 880 grams

All beans were physically different and also processed differently so they needed special approach
With my trusty KKTO I did a 3 minute stabilisation roast just to get a level playing field for all the beans

Then I just roasted them as per normal
1st crack was at 11 min 30 sec but I did observe 3 separate crack periods 30 to 40 seconds apart 


2nd crack was 7 min later at the first sounds of pops and dumped to cool
Roast colour is beautiful and even across all the beans

The wife said she wanted caramel tasting beans

I hope this mixed bean roast will produce what she requested

Sound good i cranked out 1.2nd of Venezuela San Christobel in the KKTO just before we left on our month long road trip which is my largest ever roast on this device and prob marginally over capacity for the machine - but still a lovely even roast which I've been enjoying both as stiff top and plunger abs hrs drinking beautifully six days post roast and it's only going to get better!

Roasted up a batch of Sulawesi Ranti Kapua Torajah during the week and ran it through the Clever Coffee Dripper as a filter coffee, for my work - on the weekend

Aromas of figs and almonds which follow through on a roast capsicum and nutmeg infused palate !

By far one of the best filter coffees I have tried

Roasted recently on the KKTO

700 grams - Peru Ceja de Selva Estate - Organic
One of my favourite coffees since last year

Also did 2 KKTO demonstration roasts and the crowd was impressed
They were - Rwanda Gisenyi, &  Nepal snow washed pea berry

This roaster is so easy to use, even if I say so myself

Post by: Koffee Kosmo on 12/03/2011, 07:20 PM
I was asked to roast from 50 kg bag of African beans to see if the KKTO can roast them

AM can verify the description of the beans as he bagged them for me to take home
They were a problematic bean for the owner
Every time he would roast them he would get uneven roasts with many white un-roasted beans on completion of the roast

My initial view of the beans was
1] They were ungraded with over 10 differing sizes mixed together
2] They were organic
3] I suspect that there was many farms produce in one bag

So what was I to do ??

I placed 920 grams (the lot) on a plate and removed some quaker beans approx 20 or so
I placed the beans in the KKTO and started with a 10 minute pre roast 65 deg C for 5 min & 125 deg C for 5 min = 10 min to stabilise or equalise the batch

Zero time and start the roast
I had 5 separate first cracks starting at 8.5 min to 12 min
And 5 separate second cracks from 18 min to 23 min 

I controlled the roast by vision and smell trying not to over-roast the earlier cracked beans by allowing some periods of low heat  and allowing the internal bean temperature to take a lead on the speed the roast was progressing

On the last minute I removed the TO and left the beans agitating freely
This was done for the beans to colour evenly under there own generated heat

Conclusion
This was a challenge of a roast but I pulled it of by not panicking and respecting the beans by allowing them to come to there crack times in there own time and not over roasting the earlier ones
The roast in the end was very good with only 9 lighter 3/4 roasted beans found (not white)

Now to leave them rest a little while for the taste test
On Tuesday I will take a sample to the owner and present them to him for his assessment

roasted some Indian Monsoon Malabar to the first stage of second crack during the week - and I must say its one of the most enjoyable beans I've ever roasted.  Why, because they came up a beautiful orange / red colour during the roasting process, they were evenly graded and roasted beautifully, and they came up a treat as a filter coffee only 2 days post-roast - suggesting that they will age beautifully! 

Gotta get on top of this whole rotational thing by roasting at least a week in advance of proposed consumption date, as I'm putting a good deal of my home roasts through the cafe as filter coffee - and I need to have a bit more age on them - still, I'm enjoying the process of seeing how they shape up in the cup immediately post roast - and then observing the ageing process over time


Cheers,

Pat

Roasted a batch of Indian Tiger mountain a few days ago, never fails to impress me.
Took it to full city +, 14 mins to FC and stopped it 5 mins later at the first signs of SC.
Great as a shot with loads of gloopy crema and equally good as a cappuccino or a long black.
Sadly I only have a couple of kilo's left, will certainly buy more when it shows up. ;D

Decaf 2 days post roast It does not taste any good
I will leave it to degas about 5 days, like normal beans and see how it tastes then

And that will be tomorrow

Ran myself right out of roasted beans a couple of days ago so down to the shed to roast 625g of Yirg, as usual took it to full city +, turned out well, let it degas for a full 18 hours before I broke her open, it's drinking ok but imagine it will improve over the next few days. ::)

I roasted a second batch of decaf on the KKTO again today,
The roasting process was just like normal beans

500 grams of  Columbian Mountain water process decaf

Flavour is all there, so much so that most people wouldn't know its a decaf

It's one of a few green beans that is sold by Barazi to current KKTO owners and home roasters that ring direct or visit the site

many thanks to KK for sending some superlative coffee my way - I was just starting to despair about my home coffee stakes: at home with no fresh roast and looking after two kids while mum is out, and last coffee I had at the local cafe was sub-par... what to do!

Was thinking of packing the kids in the car and driving to work to get a good cup of Joe when low and behold there is a ring at the door and the postie dropped a couple of sizable bags of KK's finest!

My faith in the world has been restored and now I think its time for another cup...

definitely looks like a pro job due to even colouration, good moisture content, and proof in the cup!

One thing I occasionally question with my own roasting on the kkto is the moisture content of the beans the beans after roasting - as even with insulation (a towel wrapped around roaster - silicon tubing kept falling off so I havent been using it) my roasts are still taking 25mins on average, and I wonder if this elongated roast profile dries the beans out?

I can usually tell how the coffee clumps or settles in the group handle, as to relative moisture content though, and the coffee feels different between your finger and thumb when its dry

anyway no such 'problems' with KK's roasts, and I havent been  too concerned with my own recently, either, and I'm guessing it also depends a lot on the country / continent of origin, and how the beans are harvested and processed, as some of the African beans especially come up a bit 'dry' after roasting - but this in no way seems to negatively effect palate structure, or depth of palate...

so to answer your question: the beans you gave me look and taste great, certainly better than many 'commercial' roasts I've looked at!

Cheers a million

Pat

Thanks for the report Pat, glad I could help

Which silicone ring is coming off
The silicone tubing does expand a little when they are new and
If its the bottom ring and slipping happens you can cut 1mm at a time to shorten

If the top ring slips off you can dab a little silicone around the pot ring from a tube to glue it in place

The towel or fire blanket should be placed over the bottom ring

Ring me if you have time and I will explain the roast methods

I was tempted by a HT.  It's the right size for me, I just roast for little old me and I can try different beans more often!  Pity they cost so much... you been saving up AM?  OR did you get a fixer upper?

I still love my KKTO KK, don't worry.

I roasted some beans up at a party on Monday.  Had the neighbours over and we got talking about coffee, they had a flick though beanscene magazine and theen asked what was that wierd thing over there ont he trolley (my KKTO).  So I demo'd a roast and gave a few bags away.  Possible customers.... They seemed amazed that you could roast your own so quickly.  They thought it took hours!

Anyway they got to take away some Laos Dong Hua Sao.  Not a bad bean so far, but I'm only roasting as SO so far.

The KKTO can roast smaller than 300 gram with a little mod
For under 300 grams the agitator end needs to travel closer to the edge of the insert
Just one end is fine, and this can be done very simply with a small bulldog clip that is available form stationary stores

This week I did a Kenya Peaberry, Peru and the Bo'oan, all 80-100gm.  They are all developing nicely, since changing the roasting I've found that they are better left a while than used straight away like I could before.  The Peru has a nutty smell, the Peaberry a distinct chocolate smell, which is different to the fruity smells I had before (roasted darker this time though) and the Bo'oan is still developing, didn't have much of a smell to start.

I'm trying the Peru and Peaberry tomorrow so we'll see how they taste.

Today the KKTO was blend roasting as a single roast
Total of 850 grams

550 grams of PNG Elephant (last of the batch)
300 grams of Brazil Alterosa AA

I am visiting a cafe and he wants a sample to try
I have had these 2 beans before and were a great combination

Mmm well the Peaberry was horrible as a long black, to me there was no distinguishing taste, it has such a chocolate smell though that I imagine it might be great as a cappuccino, I'll have to do a lighter roast and hopefully get the fruit back.  I actually tried the Bo'oan instead of the Peru, it still has barely a smell but what is there is a fruity type of smell.  I made a cappuccino from it and it goes down really well, it's sweet enough to have no sugar with.  The Peru is getting nuttier and nuttier so that will be first thing tomorrow.

I hear you RM - roasting the BOL today is the most important on my list.

As I know you love the devil in the detail...........here are the params I will be using

Load temp 200 degrees C
70% initial airflow
2 min, 25 sec turning point
100% airflow after turning point
1st crack at 9mins 10 secs
Dump at 209 on first snaps of 2nd crack
Roast time 15mins 05 secs (+/- 3 secs)

Richard here is what I can get from a non commercial roaster :)

I think it's pretty good but who knows really, I'm still too much of a newbie I think :)

I did the following on the weekend, well Friday and it's turned out fairly sweet with still a chocolate smell and taste.

Nicaragua La Gloria Las Brisas

Minutes    Heat  Fan   Temperature
0-8       7   4.5   180   
8-11           7.5   4.5   188   1c
11-13   7.5   4   195   
13-15   8   4   205   

I pulled it before second crack which it would have been very close to.

A tasting report on the Colombia Andes Santa Rita
 
Before I post my report
Please note that I have a preference for milk based coffee but have cupped on lots of occasions

Roasted just into second crack
Using the Syphon I found it very nice and smooth coffee
It has a fine chocolate tint with a hint of sweetness but that sweetness may have come to me from inhaling the essence, overall very delicate and this time my pallet could no pick anything else

In a milk drink, its remarkably the same but a little muted
It does not cut through the milk as some other beans do

Overall its a very delicate and pleasant in the cup

just finished roasting 500grm of ethiopian guna limmu , and i am a little worried that i may of took them out a tad early .
after taking a couple of other roasts a bit to far i pulled these out quicker to be on the safe side .
the temp bean mass was getting into the low 130's and that's where the last roast i did started getting a bit to smokey and i ended up with black divots in them , but these ones i just did the cleavage ( well that's what i call it ) on some of the beans was still very pale but the bean colour looks good though.
i suppose i will find out in a few days .
i am trying to get a few different beans roasted so i can taste some SO and then try some blended.

Peru Ceja de Salva Estate i roasted some on the 27/5 i had a try of it yesterday morning and it was nice .
then late this arvo i got back from toowoomba  hanging  for a coffee so i decide to give the de selva another try .only have one grinder at the moment so i had to clean out the stuff that was left that the wife was using today and made myself a cup very very nice latte . meanwhile there are 2 guys travelling through sitting having burgers one has a coke the other asks for a chino in a mug so i made him one with the de selva that i had in the grinder , when they were finished they came to the counter and commented on the burgers being great and thanking the wife for making dam good burgers then the guy that had the coffee wanted to know more about it so i explained what it was showed him my roasted on date on them showed him some greens and had a chat for 5 minutes the end outcome was he said to me well that was the best cuppa i can remember ever having so what ever it is you did just keep doing it .
it just makes me feel so dam good to know they went away happy.
and that de selva i like a lot question is can i repeat the roast  again ????.
and i have at least 8 or 9 more greens to try yet .

Did something totally different this week.  My beans stash is getting low so I did a blend of some beans and roasted them.

135gm Ethiopian Gambella Sundried (The leftovers ;) )
135gm Brazil Pulped Naturals
Topped up with 230gm Java Ijen Sundried

It roasted really well and I pulled it just into RSC @ 18mins on the KKTO.  I'll leave them a few days to degas and give them ago.

Must order more beans but just not sure what to buy ;)  So much to try!!!

Texx...

Peru Ceja de Salva Estate  and PMG Wagi AA would be my all time two beans I like the most... With MM as  the best SO.

As I am off to Morton Island for a few days... Have to get another Kg or two roasted on the weekend.

Keep getting people offering me their Commercial Roasts and I have to admit... I like my own and thos I have had from most home roasters  ;D

Those two beans are also very forgiving - you don't have to get the roast perfect and they seem to taste good at a wide range of roast levels.

I think with commercial vs home roasts, it's not the roaster or the roast method that comes through, it's the passion in the hand of the roaster and the ability to think about everything that's being done. I think some roasters get in a bit of a rut and just stop thinking about it after years of doing it over and over again the same.

On the subject of PNG........
Just a heads up......

High end PNG's are going to be a bit tight this coming crop.
I've had reports from a few brokers saying the PNG's are the best in the last 5-10 years, ideal farming conditions apparently.
As expected, the premium buyers from Japan and Europe moved early and forward contracted big slabs of the best crops - driving the price high for all other PNG's.
Word is, get in early and grab what you can - set your targets around the end of this month and through to August once the greens hit Aus broker warehouses.
I would'nt be surprised if more than 2/3 of the shipments to Aus have already been pre-sold.

I will give that a go on the next roast
The KKTO can do that very easily

The Colombia Andes Santa Rita is a very delicate bean but very nice if roasted well
Gave the first roast a test @ ten days post roast as an espresso, and it was surprisingly good
As it ages its now cutting through milk as well

Not trying to give away too many secrets, but just a tip for those of you out there looking to manage profile or "S" curve roasting.

Many of you have read the theories on endo/exo-thermic transitions of the bean during roasting cycle - so I wont repeat it here.

To manage around these transitions, you need to consider "lag effect".

If you want to move more carefully between the endo/exo stages, you need to play with your heat or airflow in the lead up to the stage, e.g. anticipate when first crack is about to happen and slow the thermal momentum down before reaching it, e.g. not much good doing it once it has started, etc.

Similarly, a common mistake made by some people is they "back off" once FC is underway, only to stall when the FC Exo-thermic stage is over and the beans are once again taking in heat. It's only natural for people to think or act this way - what they see and hear.

In other words, take your actions "before" the stages so that you can move through with control, rather than trying to respond as the thermal lag built-up within the beans are only just starting to "display" mostly once it's too late.

Of course, this all depends upon your roasting equipment and how responsive it can be to your "controls" - try to develop an understanding of the lag affect for your roasting device.

Not roasted by me, but this week I'm drinking:

250g (brown) Bolivian (somewhere???) Roasted 24/5 - Mini review: This bean was the first bean that really made me say "wow" well over six months ago. I thought maybe it wouldn't live up to my memories, but it is just an amazingly smooth bean in milk, and still one of my all time favourites.

250g (brown) Tiger Mountain Estate Roasted 24/5 - Have finished this bag now, and it has a VERY heavy mouthfeel. I feel this bean would be suited to be blended with an Indonesian bean.

Both these were roasted by Jeff (mycuppa).

Thanks Richard.

The Tiger is an intense bean - I've collected a long list of people who won't drink anything else as they are the sort of folk who are looking for a Mike Tyson type hit. When stocks of this are low, it's surprising how a Tiger fan will sit on the fence and wait for it to become available again.

My personal opinion,  Tiger is a great blending bean as it plays well with others - think inky strong infusion. There is a very well known (famous) Italian brand that uses the trusty Tiger in it's quality blend..........yes, we are talking about Illy.



Any news on the Yirgy ? I'm thinking your OH will go gaga over it.

Any news on the Yirgy ? I'm thinking your OH will go gaga over it.

Not yet. Looking at my supply, I'll be opening that bag most likely on saturday/sunday. Will be sure to let you know how it goes.

Roasted the last of my Mexico Yeni Navan Typica with the last of my Brazil Sundried Naturals today.  A 5/1 mix, totaling just over 600gm.  Gave the KKTO a good preheat 10mins+ and they roasted really nice pulled on the first snaps of SC at 18mins.  Pretty amazing considering I was roasting outside and it was a nippy 15 degrees.  Well nippy for SE QLD. :)

Down to 3-4kg of beans... must order more next week.  Any suggestions?

Tasted this yesterday lunchtime. My first thoughts were that it was flat, a bit bitter, and just didn't really like it, but I was struggling to get the grind dialled in correctly...however, this morning, now I've got the grind and pour right for it, it tastes to me very similar to Ethiopian Guna Limmu (one of my favourites), with a stronger cocoa hit, and a bit more of a lingering mouthfeel. There's also a "freshness" that I can't really describe.

It's a really nice bean - but not overly forgiving if you over/under extract it even a small amount.

The missus really enjoyed her morning cup today too :)

On topic, roasted 1/2kg bolivian (two batches) last night, one taken about 15 seconds into 2nd crack, one pulled right on first sign of 2nd crack. Just wanting to experiment with it a bit.

Also roasted 300g Monsoon Malabar.

Yes RM - Yirgy, as with most of the fruity Ethiopians have a significantly different bean structure and thus will require quite dramatic adjustment of the grinder. I usually end up with having to use a significantly finer grind. Once dialled in though, it will perform very well as you note.

Yirgy has a more vibrant acidity than other Ethiopians (partially due to the washed process and the way the coffee is graded at origin) making for a very clean cup. It's bright and refreshing.  It is milder than other Ethiopians, but what it lacks in punch it makes up for in smooth, refined and very classy lingering finish.

I'm surprised you are picking up dark cocoa (which generally come associated with a slight bittersweet taint) - I tend to get stone fruit (melon), honey and lemon through milk.

Personally, I like to extract the Yirgy at a lower temp, say 91 to 92. Higher temps tend to affect some notes. I'd probably recommend Yirgy is best used straight without milk - such is it's superb sup profile.

Back on topic - FAIRTRADE ORGANIC DOMINICAN REPUBLIC BARAHONA from the well respected FEDECARES COOP (now, that's a bean with tons of cocoa!)

The first 600g that I roasted to just before second crack I open on day 4 to start trying must say I did not enjoy it at all hope this lot's better..

But this lot was pulled short at barely at second crack

See how this goes down after a few days degassing

Today I roasted 250grams of Monsoon Malabar, followed by 250grams of Yemen

Talk about a difference in bean size?  From boulders to pebbles! 

The Yemen I'll try in a week, and by the time I've finished that the MM will have been in the bag for two weeks, which, from my reading here, seems to be a good amount of time to let it rest before drinking.

1 kg of COLUMBIAN SUPREMO "BACHUE"
1 kg of NICARAGUAN SHG EP "Pola" GREEN

These were roasted as
600 gr Light Roast of Colombian
600 gr Medium Roast of Nicaraguan
800 gr as a mixture of the 2 at past second crack and bordering on a dark roast

The Flores Gunung Inerie is almost gone, so out to shed again in 12degs wintery weather.

1kg of Nicaragua La Gloria Las Brisas.

Think this one may be quite chocolatey.  Can already smell the aroma in the bag right after cooling.

The new vac / exhaust fan cooler worked a treat.

No option other than to start drinking it immediately with a degas period of about 6 hours, will be an interesting exercise. :-\

i might do 500gr of Ethiopian Ghimbi tomorrow first try at this bean .
i think from what i have read the go would be to roast it a tad on the light side ( i prefer a slightly lighter roast anyway ) maybe dump on the first sign of 2c or just before ..
also have some Santo Domingo Cibao Altura to do a first roast on too , maybe i should do both then i can try a blend of both later when they have had a little rest .

Ha - I get the opposite in Summer time - wearing thongs near a commercial roaster is never a good idea - hot beans spilling over the cooling tray onto the tops of your feet tend to hurt a tad.

Tonight 160g peru ceja de selva. 16min 30, first snap 2c, cooled in popper as test 2min to 50degree.
150g uganda white nile -tried a classic popper roast, but still 11min 15sec, 40sec into 2c, pulled just at rolling. Note to self, don't forget to switch fan off as well as heat when dumping into cooler. Most went in, but still a  lot of cleanup. >:(

and yeeha got it working .
does this look about right .turned the heat gun down just after rolling 2c but i went a little to low and had to turn it back up a tad hence the dip .

Morning Texx,
the roast looks pretty even however 29 minutes seems like an excessively long time to me, I'm looking to be done and dusted at around 18 or 19 minutes.
Running a progressive graph can be informative and interesting until you have your process pretty well nailed, I no longer use it seems more trouble than its worth, found it to be pretty buggy with Vista.

Roasted monsoon malabar AA yesterday.  Just 300gm and roasted just into RSC. :)  Came out rather well, preheated at 150 for 10 mins, and pulled at 18 mins ish but it was rather cold outside at 4pm.

I will try it tomorrow, but I remember reading that it might need a bit longer to degass.  Is that the consensus?

texx your doing great mate.  To be honest most of this roasting your own bit isn't about doing it perfectly everytime, it's about just doing it, learning and having a laugh at the same time.  Took me ages to figure that out, and just relax, and enjoy.  At least that's how I see it anyway.  It's just fun turning a ordinary looking green bean into a freshly roasted bean in you own home I think.

Me and the missus prefer it after a rest of around 3 weeks, but honestly, try it before. It REALLY changes taste completely over that rest time, but some people love the intensity of it soon after roast. I'd be waiting at least three days, but after that, at least give it a go.

I've roasted it a few times  (first bean I ever roasted). I found that at 7-10 days it tasted awful, then came good. It is an unusual and intriguing bean - just see how it goes. If you don't like it, wait another couple days and try again as the flavour and aroma does seem to change quite dramatically over time.

Seven days on, as expected just starting to come good, in fact its drinking very nicely as a shot at the moment, shame I only have about 400 grams left.
Found a bloody great granite boulder in it this AM about 1.5 times the size of a bean, pleased I picked it up, would have played havoc with the burrs.  ;)

My roasting for tonight is the special little Tanzania surprise and the Kenya Kagongo Peaberry.

I didn't take either to 2C.

It was my first time roasting the Tanzania, within 3 minutes I had this sweet smell through out the house, I just can't place the smell though.

1C hit at 10 minutes at 189 degrees.  I stopped at 12 minutes at 191 degrees.

The Peaberry hit 1C at 9 minutes at 191 degrees.  I stopped at 14 minutes at 211 degrees.

its ok but leaves a bit of a dry mouth after .
maybe a day or 2 early yet .
question for the learned ???? i got to thinking in this cold weather ( and our shop is cold) would it not take longer for the freshly roasted beans to off gas and settle down than it would in the summer warmer weather .

johno

edit .........as i get further down the cup ( still drinking it ) the better it gets , or maybe i am just getting used to it .

Yes its possible and plausible that cold weather will slow down the degassing beans

With regards to dry mouth feel its probably the crema
Try stirring it in first

If the Ghimbi is dry processed, it can be common for DP Ethiopians that are roasted in a certain way to taste dry in the mouth, almost sort of dusty.

I've got probably 7 different DP Ethiopians (Harrar, Sidamos, Limmus, etc.) and all but 2 can come out this way unless you are careful in the roast profile.

Really nice coffee but I took it a little far I think to get the best out of it in the Syphon. Going well before SC this time  :)

ARGH I keep thinking it has been ages, the Tanzania is soooo sweet in smell, I can't place the smell though, still have four days to go, oh oh I just remembered I can try the long black with it that is spoken about in the other thread, I'll be at my parents on Saturday and they have a machine :)

I'm roasting up a load of Peru tonight for Saturday so everyone can experience real coffee instead of the pre-ground stuff my parents buy.

OK SS - you are hereby granted special privilege to get stuck into the Tanza early. I confess, I cracked it open early as well.

It's the fun of roasting - following bean development.

Right, reporting in on the first tasting, I pulled about a 40ml shot in 95 degree water.

Grinding, the smell reminded me of a bakery  ???

Now I don't want to say blackberry just because others have but what I will say is that the feel of the flavour where it 'pops' is just like a berry does when it 'pops' in your mouth.  You know if you raise your tongue to the roof of your mouth and the section that slants towards the roof of your mouth next to your molars.  There and the back centre of my tongue.

I don't know if any of that made sense.

I got that type of thing with every sip as a straight espresso.  I thought I want to have this last longer so put some more water in, nope didn't stay the same, what did happen though is as it cooled it changed again and there was another sweet taste.

The feel stays around for quite a while afterwards too and isn't unpleasant :)

Now please don't ream me for the following, I'm only new at all of this, I've been dabbling in aromatherapy for 20 years though and I think this far outweighs anything I've learnt through that.

I don't know that I believe in the getting minute tastes of different types of things BUT what I will say is that I think our olfactory senses do cause memories and that may help towards what we taste.

Sierra Leone - day 4 and it's what I imagine kitty would be if you ran it through the grinder.

10kg sample looked very low in moisture and if I'm not mistaken, perhaps the a barely distinguishable whiff of bromide (probably from AQIS).

It roasted very fast, I had to through the boat anchor out in the first ramp after turning point - almost like there was barely any moisture in the bean (reminded me of roasting some old el-salvador beans that had been lost for 4 years in the storage racks).

Anyway - even at barely any heat, it went bollocking along rather quickly and no chance of trying to be a show-off with a S-curve......so I let it take the natural course and got FC at 9 mins (even that was a big stretch) and popped it just as it started to snap into SC at 13min, 20 secs.

Slight sheen on the bean and just the first couple of drops of oil.

I'm very afraid to drink another shot.......I think my guts are rumbling already........better not go too far in the van tomorrow in case of adverse unexpected reactions.

Fired up the Coretto this morning and roasted 725 grams of Brazil Moreninha Formosa, stopped the roast just prior to second crack, plenty of chaff with this one.
I suspect there were a some foreign beans in this batch as a few of them roasted as black as the ace of spades, never experienced this before, no big deal only half a dozen or so, easily removed by hand. ;D

Got my Indian Robusta and Brazilian Dolce from Vinitasse in the mail today.

Roasted 155g of Indian Robusta. Smell straight from the roaster was wonderful. Will try as an SO before blending.

Second roast: 300g Brazilian Dolce, taken to just on second crack. After about thirty second into cooling cycle (Behmor) I opened the door, and suddenly, a substantial fire broke out in the chaff collector. Turns out some of the smaller beans had fallen out and formed a neat little pile in a hot spot. Thankfully I managed to grab a rag, pull the chaff collector out, and the roast didn't suffer.

just did another 2 x500grm of my version of the famous KJM blend , but had to make an adjustment .
the last few i have done were
de selva     ..........120gr
costa rica las pav...100grm
ugandan masaba ...160grm
sumatran gayo ...120grm
and that has been good but i have no ugandan masaba left so i have replaced it in this roast with brazilian detera instead see what happens come drinking time.i stopped it just about when i rekoned it was close to second crack or around 220c for a slightly lighter roast.
this blend is very handy cos i use it in my second grinder in the shop my wife and i like it and we use it when a customer asks for not to strong a coffee or half strength coffee .

Well back to roasting  ;D

I have done and am doing the Tanzania Rononi I got in the swap and also the Ethopian Ghimbi again, this is because these are the two I did outside last Saturday that were crap crap and more crap, all sorts of browns and didn't taste all that nice I'd have to say.

So here they are:

Besides my standard "House Espresso blend" for myself and friends (Brazil/Ethiopian/PNG):

250g MTC D10-D107
250g MTCP Organic I managed to scrounge (buy) from Kees at Mnt Tamborine Coffee Plantation when I visited a while ago.

Both roasted to start of SC. Still maturing currently, but usually they are both SOs to my liking.

I've done a 1.4kg roast in the BBQ drum of a Brazilian Blend from Ministy of Grounds yesterday. The reason so much is because I go back to work after my holidays and I will need a stash for my work plunger as well as some for home. Roasted 30 seconds into 2nd crack and despite there being not much time between first qnd second cracks (could this be because it's a preblend?) it was an even looking 20 minute roast and tastes great as an espresso only 4 hours later. The BBQ is a rough home made job but i like the taste of the roasts from it better than the Behmor.... I dont know why??

My roast for this week is the Las Brisas (yes I know I posted over there but someone wanted to know how others did it and I like to help the newbies :))

23.2 degrees start in popper
0-8 minutes got up to 181
8-10 minutes up to 193 with 1C happening at 9:30 minutes 191 degrees
10-13 minutes still climbing to 196
13-15 minutes finished at 207.5 degrees
15-16 minutes down to 62
16-17 minutes down to 39 and pulled

got a very slight sweet smell (I don't get much smell at all from my roasts normally)

I am back into pre roast blending again

Based on the observations on single origin roast flavours I decided to do a blend of the ones we liked best
Green bean blend mix is from 4 areas around the globe

300 grams of Brazil Alterosa RFA
150 grams of Ethiopian Gambala Naturals
150 grams of Sulawesi Toarco Jaya
150 grams of PNG Kinjibi AA

Total 750 grams

With all green bean mixes I always complete a 5 minute stabilizing period at 125/150 deg C
Followed by the proper roast

Always comes out even
We will taste the results in a few days

Hi KK,
Can you please elaborate a bit about the theory of your stabilizing period for pre roast blends.
I use a FZ-RR 700 roaster, and to be honest, am not happy with the result of pre-roast blending. Mixes with very hard beans do not turn out as well as I would like. Thanks.

Yes Lwowiak

The KKTO has the ability to stabilize a pre roast a blend of green beans
Its done by running the roaster with the blend from the thaw setting to 125 deg C for approx 5 minutes depending on weight

This procedure does not roast the beans it just gets them ready so they are all equal as in start temperature, moisture content ect

Then the roast starts at "zero" time

mystery roast , kinda .
dont have a clue what this will be like , i had 3 bags of beans with just a few left in them so i just chucked em all together and roasted them to just into second crack .
there was
170 gr of sumatran gayo org
290 gr of costa rica las pavas
and 80 gr of brazil datera sweet
there were a couple of beans that first cracked at about 185 degrees for some reason ( i think they were sitting straight under the heat gun and not getting agitated properly maybe i just found the limit of the bean load for my bread maker .)so 8 or 10 beans were a bit black so i took them out while cooling .

You know it's going to be one of the best roasts and no matter what you try... Never to be repeated  ;D

How is the shop and business going re: coffee ? 

plodding along nice AM , for the size of our town i think the coffee is going quite well .
i am getting a lot of people(  travelers ) that are telling me they enjoyed the coffee very much , or how nice the coffee was , one guy who has a lot of meetings over a coffee in WA in as he said the upmarket places and he said my coffee is better than most of the upmarket trendy places he has been to .
so even though we dont and never will break any records on number of coffe's sold in this little town at least the ones i do sell the people leave happy and that makes me happy .
the one thing that has me stuffed is how there can be so many places that cant make good coffee , seems to me there are a few simple rules that if you stick to you cant help but make a decent cuppa .( mainly fresh beans , purge before every shot so not to burn the coffee , also i updose ,and always pre heat the cup with a quick rince under the hot water tap )
when i clear the cups away from the tables in the three months we have been serving coffee i have only ever had 1 cup with some left in it , and that was a little old lady of about 3 stone wet through and i think it was just to much for her after a feed too so yep i am very happy with the coffee part of the business althought its not going to make me a millionair .

Today I finally got some time to roast today! :)

I roasted 250gm Malawi AA to just into SC, FC at 12mins, and pulled at 15-16mins came out lovely.

Then I just for the hell of it, I threw in 500gm CS Decaf Mocha Java that I've had sitting in the cupboard since the last Brisbane meet at Troys.  I've never roasted decaf before, but I roasted it to just into SC too and pulled at around 18mins.  It's a bit black looking.  Is it supposed to look like that?  Certainly doesn't look like any regular roast that I've done in the past.  Still an experience all the same eh.

It's good to be back roasting.

It's a bit black looking.  Is it supposed to look like that?  Certainly doesn't look like any regular roast that I've done in the past.  Still an experience all the same eh.



Decaf needs a carefully managed roast. Depending upon the type of decaf (the way it was processed) the moisture levels and bean structure could be quite different.

As you would have been starting with a darker looking green, it will in fact look quite dark on the outside when roasted and most likely oil up very quickly.

Wait a few days and then grind some, you may be surprised that the ground coffee is not as dark as you would think or a comparative dark roasted non-decaf bean - sometimes decaf can be very deceptive (appearing over roasted and dark in whole bean form).

You may have gone a touch too far, but it's a learning experience.

As a guide (depending upon roaster type) I tend to pull my decaf roasts about 1 to 1:30 minutes earlier than the equivalent non-decaf charge weight - the decaf bean is obviously much lighter and less dense in it's roasted state possibly due to a greater proportion of moisture loss compared to a non-decaf (that is, I suspect the decaf beans give off a lot more moisture, or dry out, more so than a non-decaf).

The reasons I say this - the weight of a certain volume of roasted decaf is marginally lighter, the way it runs (or clogs) the de-stoner, the way to runs through the packing machine and finally it needs more "volume" to fill a bag, e.g. more beans to reach the net weight.

Just finished an experimental roast on the KKTO
This was prompted by member mycuppa on his blog
Adding different beans at different time intervals into the roast (patent pending  ;D)

Anyway the 3 beans I chose were
Ethiopian Gambala naturals 150 grams
Bolivia Caravani  Organic    300 grams
Sulawesi Toarco Jaya          300 grams
Total 750 grams

Method of this roast as I just acted on instinct
Pre Heat KKTO approx 5 min

Using a timer for recording all of this
Drop in ambient  temp 230 deg Celsius

Drop in Ethiopian Gambala naturals for 1 minute
Drop in Bolivia Caravani  Organic at 1 minute mark and roasted for 1 minute
At the end of the Bolivians 1 minute I dropped in Sulawesi Toarco Jaya

Many pseudo cracks were heard but officially first crack was 12 min 20 seconds from the Ethiopian beans   

I must confess that I lifted the TO up several times to take a peak and check progress so it would have slowed the ramp to second crack

Second crack was 19 min 15 seconds

Overall an even roast with about 12 lighter beans in the whole roast
I suspect that they were the Ethiopian Gambala as they did show some defects and I did my best to pick out the obvious defective beans prior to roasting

So we will see in a few days how it tastes

Whilst waiting for my crate to clear  customs, 1kg Sidamo FTO Oromia, bought from Mycuppa.

A slow gentle ramp - another bean that seemed to require plenty of heat.  

Lovely aroma during the roast, and I'm looking forward to giving it a try on the weekend.   Haven't roasted any Sidamo now for many months, but the last one was a winner and I think this one should be just as good.

Since installing the new braided probe, and using a new placement right on the base of the pot,  most of the usual temperature points of interest are now happening at about 4-5 degs lower than where they used to be. Eg 1C at about 195/6 instead of around 200.  Seems to be a fairly consistant trend regardless of bean type.

Roasted 2 lots of beans today on the KKTO

From old stock gifted to me
700 grams Brazil Datera Bourbon


From sponsor mycuppa
600 grams of Costa Rica Terazzu

The photos were taken in full sun, is of the Costa Rica Terazzu

KK

Not bad KK - can be tricky with a new bean - perhaps a shade or 2 darker may bring some intensity to the bean.

It's very sweet this Tarrazu and can deliver beautiful notes of honey, lemon in very clean and bright cup.

Thanks for the compliment Jeff, the full sun photo makes it look a little lighter than it is to the eye
But such a photo can show lots of flaws. I was very pleased with this roast on a bean that I used for the first time 
Its a dense heavy bean and it went about 10 seconds into second crack

Cant wait for sweet citrus notes  :-*

Go sparingly on this one RM - the boat is still in the water having experienced some delays.

Replacement price on this bean was a bit of a shock this morning when I got the price - up around 35% on 3 months ago.

I'm trying, but it's just SOOOO good :'(

I have had to tell two people at work that I won't roast it for them after they sniffed a sample you roasted for me....I think at least one of them may be buying some off you shortly (he asked where I'd bought it from, price etc and seemed happy as he wrote it down).

1kg pre-roast blend 70:30 Sipangan Bolon & Monsoon Malabar.

Slightly uneven result - I might try this next time by starting with the MM, then adding the Sipangan about 3mins later...

Fantastic smell during the roast.   Will pack it away for a week.

Now to roast some more of Jeff's Harrar to drink in the meantime...

I'm almost through my first roast of the Tiger and not only was it easy to roast but as it ages it rounds out beautifully. Let us know what you think of this one KK.  Kudos to Jeff at mycuppa.com.au for supplying this awesome SO.

I'm running half a kilo of the Tiger Mountain from mycuppa this week, and it was 4 days post roast when cracked, and it's fantastic. Very smooth. Seems to be developing a "balanced complexity" as it ages.

Haven't roasted the tiger mt for a while, but the thick, jelly like crema and rich body are what I remember most. Currently drinking a yeni navan and tiger mt blend.

Roasted earlier today: my first attempt at PNG bannum wo. 16 min roast, FC plus 15 degrees (FC plus 3 min).

 Still getting a handle on the hottop with bean temp sensor, would like to stretch time after fc a bit and speed up ROR after drying phase, but at the moment it struggles to get above 13 degree/min ROR.

Sunday is the best day of the week (apologies if I've offended any religious folks).

What's even better about today is that it's too wet to mow the lawn and it's a sort of crappy Melbourne I-can't-make-up-my-min-weather sort of day. Another perfect day to be stuck inside roasting.

Today's agenda- .........

Honduras and Guat COE
Sidamo - the Emporer Haile Selassie
Stunning Lake Tawar
Rwanda Inzovu
Secret Men's Business PNG RFA
Indian Elk Hill Estate A Natural - better than the Tiger !
Columbian Equidad FTO
Bolivia Montana Verde FTO (new crop just arrived last week)
Uganda Bugisu (new crop - super fat & funky)
Honduras Minas De Oro
300+ kg of blends
some decaf (poor souls)

Alright Jeff, I'll concede that your volume is a little more than me and my Bwhmor.  Today I am roasting 400g of Nicaraguan RFA SHG La Bastilla.  To compete with Jeff I may fire up the KKTO, all the poppers and redirect the ol BBQ roaster and roast all my beans.  I'll be short of his 300kg by about 250kg so I'll have to scrounge the neighborhood for seed, gum nuts and other flora... I suspect the cupping of my roasts may be 'coffee to die for!'  :o :D

1kg Harrar Star double sort.    Almost lost the lot with a reactor meltdown....   :o

The trusty pool pipe on the cooler, which has served me faithfully for many a roast, decided to melt with half a kilo of beans stuck inside....   Anyway, after a quick amputation, it's shorter now by a metre or so and hopefully will be ok. 

After all the fuss, I then did 850gm of Monsoon Malabar.

Today I roasted some beans that were gifted to me
Vintage beans from 2006/2007 as far as I can ascertain 

Called
Red Sea Blend from CS

Once inspected I saw that they were very very dehydrated
I got them as an experiment to re-hydrate

Over 2 to 3 months I re-hydrated them slowly
Method
Place in a double steamer pot system
Beans in steamer insert over filtered water in the lower pot

They were left in the open weather outside
With the occasional spritz & stir every few days

Once re-hydrated they were then left/stored again in the cotton bag for many weeks to normalize

It was approx 700 grams

I will see how they go in a few days after a degas

KK, will be very interested to see how the Red Sea blend works out.

I've often roasted beans 2+ years old without a problem, but as it happens RSB (Feb 07) is the only one where I've thrown some out. I found some early last year and decided the "mouldy" aroma was a bit much. Not to mention the severely dehydrated and highly discoloured appearance. With some regret I must say, it was magnificent in 07.

ANyway, back on topic, what did I roast this week? 180g each of Tanzania (yesterday) and Yirg (today). In the baby roaster, as we are house sitting this weekend and the Quest was a bit much to bring along. Gas ran out on yesterday's batch, luckily just before the expected finishing time, and they chew and look pretty good, so should work.

A nice balmy Adelaide evening & the first roast since a major cooler meltdown last time.   I am now the proud owner of a top of the line  ;)  $40 Homelite shop vac from Bunnings.  It's made a huge difference and now no more beans coated in melted pool pipe...  Also, back to back cooling is no longer an issue.

The MM was so good I did another kilo and bagged it up.  Have to think two weeks ahead with that stuff.

Next was a kilo of Yirg Harfusa - this lot will wait a week then be cold brewed, filtered and matured in the fridge for a while.   It's great as an iced coffee  :P :P

And lastly, a kilo of Sulawesi Toarco Jaya.   I wasn't all that impressed with this one last time, but will let it rest 14 days this time before opening the bag.

Enough work for one night, and now off for another MM....

Since becoming a roaster and reading a fair bit about blends and blending, I've noticed that quite a few blends have a minor percentages of Robusta included. So I decided to get my hands on some, Indian Monsoon Robusta Parchment R  (don't know what the R stands for). I roasted some of this and decided to have a short black using this bean and nothing else. My God, is that in your face or what!! Is that why small amounts are used in blends?
One thing I must say, it had a beautiful Crema.

Look at the large amount of chaff that has not been removed during the roasting process.

Yum!  This is a seriously good bean and I'll be good and eek it out over the next three weeks.

I have already been through 4 kg of this bean and just recently got another 4 kg - great on it's own or in a blend with some Harrar and Colombian Supremo as I often have it

1kg of pre-roast blend 50:50, Festive bean swap 'X', and Festive bean swap 'Y'......    ???

and another kg of Festive bean swap 'Z'.       

Bean 'Z' came up quite nicely, and the blend should mature well.     ;)

For the Espresso blend I used Brazil BSCA blend from Ministry Grounds. [Using up end of bags].
I am drinking a flat white at the moment, and it is very nice. A well balanced and smooth espresso, that is also nice in milk. Tastes like "coffee".
My wife loves a 50/50 blend of the Yemen and the Brazil Daterra in a latte. As the Yemen develops the flavours change daily.

Just roasted some Nicaragua Cup of Excellence Lot 13 Misael Saucedo Olivera Washed Maragogype sun dried 'La Bendicion' Los Plans, Las Mans - 1300masl - yep, its a mouthfeel in every sense of the word!

Did a 5min preheat @ 200C then added the green beans to the KKTO and I must say (I normally add the beans at the beginning of the preheat) - the difference to the roast was astounding!

First the roast came up to temperature, second I shave five minutes off of my usual roast times, and third i am really happy with the evenness and consistency of the roast

proof will be in the cup tomorrow!

Nearly ran out of beans, but had a few mins at the weekend to roast up an emergency batch. Time was tight, so grabbed 250g brazil monte alegre, threw in 50g monsoon malabar to give it some kick ( the bag of mm was first to hand).

Plan was to use full power to just before 1c, then ease off and finish 3 - 4 mins after 1c, just before 2c.

Not my best choice of beans for a rushed emergency  roast
 :doh:


First crack seemed to happen twice. Mm not a good choice when beans will only get a short rest after roasting.

Ah well at least it is coffee and I will remember next time  and use the tiger mountain that I know works with the brazilian

roasted a couple of batches for CP end of last week (DR Constanza and Harfusa). The Constanza is brewing as I type.

Today was 220g Honduras Finca El Filo CoE.
Ran pBourbon  to monitor this one, screenshot attached.

I think I'll whack a bit more heat in next time after first crack, slightly too gentle this time.

Now I just have to wait a few days to let it rest. Smells nice already.

Under a 40 degree day, Pre-blended a 3 bean mix of 180 gms Bolivian Green Mountain, 180 gms Sumatran Sigararutang and 230 gms Tanzanian Uru. Roasted 3 batches back to back.

Next door smelt what went on and scrambled to gather their laundry which had been sitting out since yesterday. Hehe.

Now settling down to a tall glass of Passoa passionfruit liquour and lemonade and rattling the keyboard.

As usual, pre-heated the KKTO for 5 minutes, zeroed time, full heat at 250 degrees C and then roasted til 30 seconds into second crack at 21 minutes.

Looks evenly roasted for a pre blend, though i could have just roasted indiviually and post blend if doing 3 batches. Being half tanked does that to you. Cool

Did i mentioned it was darn hot today? Merry Xmas to all.

Excellent looking roast Marc.

Perhaps it's the light, but the roast depth in my mind looks almost perfect. My guess is it's about 20-40 seconds into SC.

Java and many Sumatrans can respond exceptionally well to a slightly darker roast (or increased applied energy).

Yeah - good work with the Java - I think you nailed that one perfectly and let it develop adequately before running it through the grinder - min 7 days, but try 9 if you can.

The Harrar may be a tad on the light side by looks of the image - could be pic though. Always a beast/devil to roast - has a tendency to accelerate in the 1-2 minutes prior to SC and can catch many a roaster by surprise.

As you know, the uneven roasted appearance is OK for these DP Ethiopians as they contain quite a wide variety of fruit maturity (under, ripe and over) and the DP technique introduces quite substantial variations in the cup.

Whilst there is a tendency to go light on these and other DP Eth's I would suggest a slightly darker roast to ensure adequate roast development of the "wild" beans. When I say darker, probably similar to your Java in terms of roast level. Of course the DP Eth's will not show dark roast levels externally (appearance) so maybe 15 seconds into SC and super quick cool if you can.

It also depends upon your target brew method, but again for the Harrar I advocate a decent roast at least for all major brew methods - in my experience there is very little to be gained by stopping light on the majority of Harrar's imported into this country.

Post by: Muscles on 07/01/2012, 12:29 PM
It's a bit shaded on my balcony at the moment so getting acurate color/lighting is a chaellenge but I am glad you approve (?). I must confess I didn't do any form of drying stage with any of these. I preheated to 180deg before putting the Kalistat in and the others were just back to back roasts. Do you think with a purposeful extended drying stage that the Harrar would have come up more even? Or is it more so that this lot of Harrar I have varies a lot in bean size/mass? - It is quite a bit different to the Harrar I got from you...
Title: Re: What coffee are you roasting this week
Post by: mycuppa on 07/01/2012, 12:38 PM
To be honest, I'm not experienced on KKTO roasting to understand the pros and cons of specific drying stages in a roast cycle.

In relation to drum roasting, I found it is not necessary for my purposes, others may use it, particularly very large batch systems but it's literally impossible to know who does what as everyone protects their IP extremely closely.

I would have a stab at suggesting it may not have made much difference to evening out the roast appearance as the process may work better when the bean consistency is higher (closer screen size and more even processing method, e.g. washed). In other words you may be working against a great force that being the diversity of the bean.

Yes, you will experience dramatic differences in the DP Ethiopians where they are Harrar's, Yirg, Sidamo's or the odd Limmu.

I've been roasting the DP Harrar in my KKTO for a while, and unlike other beans, there is always a little bit of variation in roast depth across the beans, but it still tastes great.

I routinely use a 5 or 6 min drying or pre-heat stage, with the bean temp at 40-60degs.  My normal roast profile starts after that, and I purposely slow it down to around 20 something minutes depending on bean type and batch size.

I also pre-heat the oven empty to get all the bits and pieces up to an even temp before use.

Here's a profile that I use for a 1kg batch size:

The beans I chose were on purpose (see flavour description of beans)


Bean Roast 1
600 gr - Kenya Karogoto  AA top - Orsir Special lot
Roasted 20 seconds past second crack
* These beans were kindly gifted to me by Mark of Supreme Roasters*

I was told that they had a cherry wine flavour

Bean Roast 2
600 gr - Peru Ceja De Selva
Roasted a little lighter than the Kenyan at just on second crack
These beans are a favourite that has a lovely chocolate flavour

So my humorous side kicked in   ;D
This combo is - Cherry Ripe mmmmmmmmmmmmm   :P

It was a bit larger than my normal roast at a tad over 700gm and it was a bit slower, but came out very even.  I just threw in my remaining PNG AA because there was very little left.

Wow... that looks wonderful!  Very much to my tastes I suspect.  I have done a weird one inspired (for want of a better word) by my friends Nespretcho Ristretto podette.  When I tasted it I wondered how I could recreate this for him highlighting the burnt overexctracted nasty taste that he so loves and admires.  So having bought DiBella refillable pods I roasted the following:

180 Mex Cassandra
120 PNG Ondu
60 PNG Robusta

This was roasted to a very dark French Roast in the Behmor.  Burned caramel and dark chocolate flavours predominate at lower temperature )91deg) extraction and lively acidity cuts through milk beautfully at a higher temp (93).  The higher temp was too rich for my palate but the lower temp as a piccolo latte is very nice but longs for a Cognac chaser!

As an aside, my friend won't let me near his Nespresso machine with my home-made pods becasue my first attempts caused the machine to stall and he reckons it hasn't been the same since.  YEEEEESSSSSSSS!  :thumb:

Down to the last few bags in the leftover stash now.....

Tried a blend this arvo:

450g Nic Glorias Las Brisas
450g Ethiopian Ghimbi
150g Indian parchment robusta

Talk about striking it lucky....  This blend is a cracker, even only a few hours after roasting   :coffee2:

The two group is awaiting removal of a cracked 1/8 blind cap, so I tried it in the aeropress.   

As a medium roast it was rich & smooth, with the ghimbi dominating but also a bit extra punch from the robusta, and a more rounded flavour than just the ghimbi alone.

Hopefully the 2 group will be back up and running in a day or two and I can try it as an espresso...  :P

That's a pretty good ramp there Stu.........
In the absence of tasting what's in the cup, based on my assessment of the appearance of your curve and comparing it to my commercial equipment I would encourage other home roasters using similar setup to Stu to perhaps compare your curve and Stuarts as a good example.

It has all the hallmarks of a good linear ramp and a slowing drawn out roast development stage between FC and SC.

Excellent stuff !

Don't know the behmor, or how quickly you get through your coffee, so following is just a guess.

One school of thought is that you should start tasting asap when learning a new roaster or beans as you sometimes get surprised. Generally I like beans best one to two weeks post roast. They will taste different at different stages, do experiment and see what works for you. Try to keep some beans at least ten days.
 Good starter bean.

Columbia La Union Excelso, about 30sec into second crack.
Not totally happy with this roast, as I have never roasted this one before.


I do however have some browns roasted by mycuppa for comparison purposes when tasting time comes.

Would welcome any comments. If I can, I will attach roast log and photo

Oh - 230g green gave 192g brown.

Sorry - photo not very good. They are a tad lighter than in the photo and in better focus :)

I found time to do two roasts on Friday night.

A decaf, which I'll talk about in a different thread and a five-bean blend.

The 5-Bean blend started out as a four-bean suggestion from RichardM, but morphed into something else on the fly. I'm trying to use up some of the beans that haven't seen much action yet.

It was;


180g Kenyan Dorman Estate
120g PNG Kimmel
120g Dominican Republic Cibo Altura De Constanza
100g Brazil Daterra Estate Sweet
80g Monsoonal Malabar

I roast on the balcony, so the last few weeks it's been challenging trying to find a time when the balcony isn't soaked or actively being rained on. So when everything calmed down a bit on Friday night, I grabbed it.

The decaf was first and went well, but by the time it was over the weather was closing in and the radar was showing a large bank of rain coming my way.

I went for it, but missed the start of second crack because the wind was so damn loud! Pulled at 19 mins in the middle of rolling second crack:

(http://i.imgur.com/Msj0Jl.jpg)

It was a fair bit darker than usual, but still very even. I've been trying it daily since and I think the MM is a little ashy in this case, but the flavour is growing nicer each day. Hopefully it'll last long enough for me to taste it in its prime!

I probably won't go this dark again.

UNM - Colombians can be deceptive to roast - they have a tendency to show a lighter "monk-brown" roast level. Most roasters see the lighter color and then go darker - some colombians can handle quite darker roast levels without breaking down.

You might be surprised by your result.

As I've only had 1 shot at this bean so far, I also thought I had gone too light.......but it's likely to develop ok.
Title: Re: What coffee are you roasting this week
Post by: UNM on 31/01/2012, 03:20 PM
Jeff, not too worried about colour as I only look when the beans hit the cooling test these days.

my little hottop struggled to keep temp rising fast enough from about 130 degrees, then it ran away a bit just before first crack and I'd  like the first to second crack to be a bit slower. At least that's what I THINK would be better.

Tasting will be interesting in a few days.

I'm just roasting a blend 600gm in total.  My effing neighbour has just started mowing his lawn.  So I guess I'm doing this one visually. :(

Anyway 20% Brazilian sweet, 20% png elephant and wahgi AA, 30% java, 30% mm.

Tried this a while ago and it was lovely around the 12-14 day onwards.  Roasted just past 2nd crack.

Bit slow fc 16mins. Sc and pulled just after at 22mins

On Sunday I roasted this blend:

180g Kenya Dorman Estate
180g PNG Kimmel
120g DR Cibo Altura De Constanza
120g Indian Monsoonal Malabar

I've been hunting for a blend that uses the crema and power of the MM and gradually increasing its presence in my blends over the last few weeks.

I'm hoping that the DR will add a little brightness to the smoothness of the base beans, while the MM adds crema and oompf to the blend.

I had a taste each day so far and it's very very smooth so far, can't wait to taste what it matures into.

As a side-note, I've been making my wife 50/50 blends of 'real' roasts with the decaf because she's not a massive fan of the decaf taste by itself. This blends extremely well with the decaf to produce a smooth and flavoursome low-caf brew.

This week I have done four roasts on the Behmor:

Want a nice Mocha\Java blend (am up for suggestions but this was it):

300g roast
50:50 blend
Yemen Sawani Mocca : Sumatran Mandheling Blue Batak
1Ib P4D start +90sec, externally cooled and CS9.  Three days on and I had to try it. Think this one will grow :)



300g roast
Indian MM
1IbP4 start +90 with 1.30min preheat
1C@ 7.32, R1C@ 7.15, brush in door
2C@ 1min, pulled and external cool with 253g recovered. CS7-8 or so

KJM take offs to try:

300g
72g Peru Ceja
60g Guatamala Huehue
96g Ethiopia Yirgacheffe
72g Sumantran Gayo Speciality
1IbP4D start +90sec, pulled at 2.5min to go on rolling 2C.  Nice CS9

300g
72g Brazil Daterra Sweet Collection
60g Guatamala Huehue
96g Ethiopia Yirgacheffe
72g Sumantran Mandheling Blue Batak
1IbP4D start +90sec

All these tasting are happening via a porlex grinder, Breville 800ES or the work Sunbeam EM6910.......... No justice but the guys at work have been enjoying the Peru as long blacks!!

Some great looking roasts there Jonty!  I particularly like the look of the last one but I would swap the amounts of the Yirg and the Hue Hue for my tastes.  Like your Mocha Java take also.  Have you tried Java Kalistat yet?  That would be an awesome substitute for the Blue Batak... I think there has to be some more Yemen in my upcoming greens order.   You've whet my appetite!!

Quick report on the above blend - here it is again for the desperately lazy: ;)

180g Kenya Dorman Estate
180g PNG Kimmel
120g DR Cibo Altura De Constanza
120g Indian Monsoonal Malabar


This is a bit of a winner. I pulled a fairly perfect double ristretto this morning that was thick, syrupy and very very smooth. Still just enough brightness to make it interesting and some strong flavours I couldn't quite pick.

My sister in law has recently switched to long blacks (no sugar) after discovering she's lactose intolerant. I gave her this yesterday and her response was: "Wow.... is there a hint of toffee in here?".

That was the flavour I was tasting also.

I just roasted up a second batch of this blend from two weeks ago:

180g Kenya Dorman Estate
180g PNG Kimmel
120g DR Cibo Altura De Constanza
120g Indian Monsoonal Malabar

Gotta love the KKTO, so repeatable - FC came bang on 10mins again and was pulled at a comfortable rolling 2nd just after 19mins.

I enjoyed this roast so much I had to do it again. My wife's loving it in milk also. I mix it in 50/50 with decaf so she gets just a little bit of a caffeine hit in the mornings.

I'm using the same quantity but they have different weights, already I've noticed a difference, the Honduras needed a much higher fan speed than the Tanzania.

I got some time to myself today and needed to roast for next week so I roasted up a CofE El Salvador Lot 29 Las Nicolas what was a Christmas pressie from our excellent sponsor BeanGreen.  I only roasted 300gm of green which will do me for a week and leaves me about the same to do another or possibly blend.

I preheated to 125oC, dumped the beans in and I hit 1C at 9mins.  Nice loud cracks too, great stuff.  Very even roast, and I burped the TO a few times, and pulled it just as RSC was kicking in, around 14-15mins.

The roast was very even.  Can't wait to crack the bag open...

I roasted on Wednesday night 300g of PNG Wahgi AA for a work colleague after he told me he paid $14 for 150g SO Indian bean in the burbs of Melb.......... He has a Jura Coffee Machine.
I haven't even tasted the PNG Wahgi AA myself as I just got the beans the day before.  So hopefully with a weeks rest and cooled just a 2nd cracked started, he will have some delightful coffee.

I have since dropped him mycuppa details as he is based in Melbourne.

I did three roasts today.  This is the first chance I've had since the Bub was born along with work going into overdrive.  The KKTO didn't miss a beat:
 
550g 50/50 Columbian decaf/Daterra Opus 1
700g El Salvedor Finca el Carmen
1000g 40/40/20 PNG/Mexican/Indonesian washed Robusta

All nice medium roasts with the exception of the last which was a touch lighter because it's for plunger coffee.

Today, I decided to do a few back to back roasts while entering my accounts into MYOB and testing the last EM4800 before it finds a new home tomorrow.

250g Peru Ceja de Selva
250g Dominican Constanza
200g Monsoon Malabar

None of them were exactly what I wanted - that's the trouble with doing 3 or 4 things at once. All OK, but not quite what I was aiming for.

Just enough MM left for one more roast, will do that soon while I remember how it behaved so I can get better results. Just realised I have never roasted MM as single origin in the Hottop before, so I guess I shouldn't have expected to nail it. At least I have the roast data for that one saved.

I had to roast today before I ran out of my SO, so I roasted 30% Java Ijen Sundried, 30% Costa Rica Herbazu Estate, 20% PNG Wahgi AA, 20% Brazil Daterea Estate Sweet Collection.  A bit of an experiment using the Costa Rica bean, but I've ran out of Indian and didn't fancy MM again (takes 10+ Days to settle for my lusso).

I pre-warmed my KKTO at 125C, used 600gm green and hit 1C at 15mins, let that roll into RFC burped and hi SC and pulled just on the first snaps at 21mins.  Nice roast, and 520gm roasted. :)

The CofE El Salvador Lot 29 Las Nicolas hasn't lasted long, it's very nice even in milk.  Must try a long black with it when my sniffly nose goes away.

Just did the last batch of my Kenyan/PNG/DR/MM blend that I've enjoyed so much these last couple of months.

I took it just a little lighter this time as I've become aware of a taste that might be characterised as 'ashy', so thought I'd try pulling it faster and try for a medium roast. Oddly, however, the roast itself progressed much faster than usual, even though the night is cooler than is typical. It seems fractionally light, but we'll see.

Yesterday while baby wrangling I roasted a 1kg blend of PNG Robusta/Mex Finca/PNG Kimmel/Sumatran Blue Batek (10/25/35/30) Medium+ in the KKTO.  Smells great this morning but it's for my holidays end of next week.  This week I am drinking the last of the Tiger Mt as a single origin and I've also roasted one Costa Rica Tarrazu although reading Ash's comment perhaps this should age also.  Gosh I'd love o buy some more Tiger Mt beans (subtle hint... subtle like MM or AM for that matter  :rofl:)

The Costa Rican should'nt need too much rest, but that depends upon how it was roasted and how fresh the greens were (fresher = longer rest).

Tiger is on the radar for May/June. We are contemplating another 5+ tons of it. At the moment though, we have a Guatemalan that runs rings around it, but alas it's likely to be short-lived.

New crop Indians should start landing in late April, so we will have a bake-off between the Elk Hill and the Tiger Mountain again. I've forwarded a few ton of the new, untested Elk Hill on the basis it's just been so damn good and last year the Elk clearly beat the Tiger. Unlike the laws of nature.

Second time roasting MM.  Took 400g on the Behmor using 1IbP2C, right into rolling 2nd crack before throwing it into the external cooler.  About 3min between 1st and 2nd crack. Let's see how she fairs this time, a little deeper in colour than my previous MM roast.

I'll crack it in a couple of weeks time.

First roast with the KKTO here in Dubai....    1kg of a dry process Yemen, roasted in the cool evening air (33C) ;)

I arrived without my stash of green about a month ago and have finally found some time to set up the gear and get roasting again.

Being caffeine deprived and desperate, i took a punt and bought 6kgs of Yemen (unidentified), from some spice traders who had a stall at a big trade fair / fun park which is close by. http://www.globalvillage.ae/ (http://www.globalvillage.ae/)

It's a small dry process bean, with quite a strong aroma when green, and comes with free rocks and various other bits and pieces.

Anyway, it reminded me a bit of yemen bani Ismail so i bought it for about $12/kg.

2 days post roast and I'm glad I did. Smooth and semi sweet with plenty of body (aeropress). Shame the stall is shut down now for the summer but I still have their contact details in Yemen so might get some more.

When I get some more time I'll post up some pics of life over here.

Cheers.

On Tuesday I roasted up some Yemen Sanani Mocha - looks good so far, and tonight I roasted up a batch of Java Ijen Sundried. I'll end up blending 50% of each bean for a Mocha Java blend. Next up will be a batch of Nepal Plantec Estate - a bean that I am quite intersted to try  :coffee2:

Thanks Marc.  It smells divine this morning but I'll leave it in the one-way valve bag in the cupboard for a week.  Then I'll have the excitement of finding what temp I like best for extraction.  Serious fun eh!

Been a busy couple of days this week on the Behmor as I was seriously concerned at the amount I was starting to chew by playing with my new toys.....  This is what I have on stock roasted:

11/4 did a 300g batch of Costa Rica Iterbazu Estate (if I can read Brendan's writing  ;) )

13/4 did a 300g batch of El Finca Carmen - been enjoying this one at work.

14/4  did a 300g batch of Kenya Gethumbwini peaberry & Rwanda Cyarumbo

15/4 did a 300g of Indian Elephant Hills

Got a 350g stash of MM roasted on 25/3, so feel free if you think I should post roast blend any of these.......

This thread seems kinda busy right now. Best chip in

2 batches of 280g each four bean blend of equal parts Tiger Mt, Java Ijen, PNG Highlands, Malawi Nyika

also 230g Mex Yeni Navan.

That'll do for a few days. Next up a Guatemalan methinks. Then probably  another Harrar/robusta for a little experiment

I did 2 lots of 70/30 Brazil Sweet/Harrar, I felt the Sweet needed a little more omph hopefully the Harrar will give it.

I also took a video of the roaster process, I put it in the Projects section under my thread for my roaster.

It was picked by me because its easy to roast & it sells quite well
But also very nice in the cup with or without milk 

I found it best to roast the Colombian Supremo "Bachue" to just on the onset of second crack

Title: Re: What coffee are you roasting this week
Post by: mycuppa on 16/04/2012, 07:43 PM
KK  & others.....

For some (I would say many) Colombians, there is a sweet-spot either side of 2nd crack, e.g. the spot you found and the spot just darker.

I tend to put them in the earlier spot, but have had tremendous success with sublime rich caramel/honey on the darker side. In fact, the results on the darker have been stunning.

Couple of points to note:-

1. As we have noted before, there are beans and there are beans. Colombians tend to be a softer bean so you need to pick whether the cell structure can handle the higher finish point without breaking down. I tend to see Excelso (smaller) beans being able to run further than the larger, puffier Supremo's - but it's horses for courses.

2. I've found the spot in the middle (between the 2 sweet spots) can give a very ordinary cup......so tread carefully.

One week on I've cracked this today and fluked the grind to give 60ml from the 18g VST basket at 92degC.  Lots of chocolate and chicory with a really syrupy mouth feel.  This one I reckon will only improve over the next two weeks.  It has lived up to its promise and will go into the book.  This is not so much of a Kapow but more of a Mmmmmmm... Yum!

So Alex the Builder,


What beans are you roasting this week  :stir

In the AM loaner HT I'm doing some peaberry, honduras coe, MM & some indo kuta - along with some Peru Ceja de Selva Estate, Not sure whether to blend them or drink as is. I am digging myself a hole though, in that I want to taste everything which is freaking the grinder out. Wild variations in grind between different beans  + the freshness means I'm wasting a lot. Ah well, cost bugger all compared to buying browns

1kg of 'lucky dip' Yemen. Need some beans to take with me on a 4 week trip leaving tomorrow. 

Still been ridiculously busy with the new job but can see some light at the end of the tunnel once I get back.

Will have to buy a box of decent 500gm bags when I get to NZ.  The only bags I've managed to find over here don't even have the one way valve..

I've rebuilt the bucket / vac cooler after the vac sucked a bit too hard and the whole thing imploded. At least I managed to salvage the beans!  The collander is now held in place with metal brackets and bolts.

These yemeni beans are hard little suckers that take a lot of heat to roast, so the slow cooling didn't seem to do them any harm.

And here's a pic of my temporary roasting setup on the back step.  Have to get a roasting table / bench sometime soon...   :doh:

Quasi roaster at the moment. One day (very soon) a KKTO will grace the deck and I can get stuck in. The HT is a great intro and I'm super thankful that AM loaned it to me while he jet sets around Nam' but I'm looking forward to stepping up on several levels, batch size most importantly

Thats the biggest problem. I cut off the store bought beans and started roasting which means I drinking too fresh at 2 days ( or sometimes same day) but I'm going for it to try and build stock. Not easy with the small batches and other crap going on ;)

It's a non scentific mix of
Ethiopian Harar 300gr
Indian Monsooned Robusta 300gr
Cuba Altura 150gr

 So I will see how it goes
Probably a little strong

This mix was prompted because of AMs trip to Vietnam and all the talk of Robusta

I love the Deterra and Sidamo so if it were me I'd go 60% Deterra, 30% Sidamo and chuck in 10% Robusta just coz that's what I've been trying lately. 60/40 Daterra/Sidamo should go well as is but I reckon the PNG Robusta will add a little extra oomph...

Snap - I did three batches early this morning (hint: don't let kids choose a sport that can possibly start at 7am Sundays), all 350g 1P2B.  The last one I was day-dreaming and didn't wedge the door after 1stC so hardly any gap to 2ndC - Oh well, It'll be interesting to see the difference.  Bit of a chaff monster.

Just did a back to back roast on the KKTO of 800g of India Monsoon Malabar AA, and 800g of Bolivia Green Mountain

The Monsoon Malabar was a tricky beast as a fair proportion of the green beans seem to be under-ripe - so I pulled the roast about 20sec into 2nd crack, and sorted by hand those which failed to make the mark - probably 40g in all so not too bad really

Then I dropped the Bolivia into the roaster immediately after cooling the Malabar down, and emptying the chaf - and this was a dream to roast by comparasen - with lovely, even colouration, and obvious progression between !st and second crack

I took this one a little bit darker than the first - but only by about 20sec, and I'm happy with the evenness and colouration of the roast

Both roasts worked out pretty well, and I've a feeling that I'll be sampling them both at work this weekend!

Cheers,

Pat

Excellent effort SS - nice even depth and excellent roast development - the technical terms escapes me once I've consumed a few drinks.........it's what I call the "puff factor" of the bean.

Panamas are lovely to roast - generally roast very evenly and can surprisingly take quite a lot of heat without breaking down or showing signs of scorching or tipping.

Having a PNG couple of weeks. 3kg of PNG Wahgi AA I had from last year and another 2kg of some PNG Gouno as well.

7kg extra PNG Wahgi arriving to test with plus I have found another bag since. Plan is to roast 4 or 5 roasts of it this week and then the rest the week after to set a benchmark and some starting rules for my new roaster.

FREE Wahgi anyone? :)
Seriously if anyone would like some then for around 500g for $8 or 1kg for $12 to cover postage and a coffee bag or two, apart from some for my cupping and testing I am going to be giving the rest away locally as I play. Bit like a drug dealer giving out free samples  ;) Drop me a PM.

Mind you it was a chafey bean and the colour etc was interesting...  Enough chaff that I could have mistaken the bean for a parchment type.

I've read this a couple of time now from a few people and it's got me a little intrigued.

Surprisingly, I don't get a whole lot of extra chaff when I roast it - for me it's just like any normal/standard washed central in terms of chaff generation.

That COE from Brendan smells like a fruit salad /Monsterio delicios and thats when it's GREEN...

I haven't seen anyone else other than you comment on this, but it definitely is the best smelling green bean I've ever sniffed. Amazing smell.

The chaff seems very "light", so it's possible that just with our types of roaster that the chaff is getting big updrafts, and taking up lots of space?

Rwandan Musasa taken to first snaps of 2C.
Sumatran Aged Late Picked taken 20sec into 2C
plan is to try them as single origin and also blended after resting for 7-10 days :)
tried the Musasa in my Clever Dripper yesterday, produced a lovely juicy brew displaying a creamy mouthfeel with choc/fruit notes -a most pleasing bevy :thumb:

I made a similar blend last month:

Roasted to start of second crack (in a KKTO of course

Very nice after 8 days and developed to become even better as it aged further.

Did a couple of roasts tonight that I've been trying to get to all week.

First was a mix of Brazil, PNG, a central I don't recall and some MM. I've been trying to increase the time between first and second crack by burping in the leadup to first crack and then turning the temp down to just over 200 once FC is in progress.

The result was an incredibly even roast that finished up at 22mins and was about 8 mins between FC and 2C, pulled on the first snaps. Smell is incredible, can't wait for the taste.

Applied the same technique to the last of my Brett H de-caff special blend and had similar results.

Interesting idea and technique mate.  I'll have to give it a go.  I'll admit that quite frequently the time between first and second cracks for me has been negligible.  I'll do it carefully so as to not stall the roast. Ive also cut a 1/2" portion off my silicone tubing to vent some of the chaff and smoke and found that this has helped increase my 1-2crack times as well as vent a significant amount of smoke and chaff without changing the roast times.  Food Coffee for thought. 

On a side note I did a decaf roast yesterday using the Columbian nd the Brazil Opus One. I pulled it a little early as an experiment.  The result today is a decaf roast that smells truly divine and tastes like blue cooch  :doh:
Title: Re: What coffee are you roasting this week
Post by: Kelsey on 15/06/2012, 09:31 PM
I've always had reasonably good time between FC and 2C - just lucky I guess, certainly wasn't skill. Usually at least five minutes. But my silicone tubing has never quite met and there's always been about half and inch gap that vents smoke - quite handy really as I can be off doing other things and watch for the smoke to know its time to take a look! ;)

I still love that decaf blend of yours tho, I frequently wind up drinking it in a 50/50 shot with full strength beans and it's still great.
Title: Re: What coffee are you roasting this week
Post by: mycuppa on 15/06/2012, 09:54 PM
Folks,

I continue to see considerable energy invested by people who are quite literally obsessed with "drawing out" the roast development time-frame between FC and SC to the longest possible period in the hope it will yield a magic result.

It all depends on your equipment, roasting method and many other factors that occur in the leadup to FC. I think it would be very difficult to apply a general rule across the myriad of different types of roasters that people use.

I will put my hand up as one person who has gone from one extreme to another over many 1000's of batches to search for the holy grail in determination of the best "target RD time".

One thing I've realized is I used to think it MUST be 5 mins or it will just be shite - nope, 3 mins can be superb for some beans and profiles and a lot has to do with thermal transfer and air flow. Whilst this next statement may raise some hecklers, in fact, under some circumstances 3 mins can be a safer option than 5 mins. This is what I've learned for my style of roasting.

I'm not trying to steer people down a rabbit hole.....just use your cup as a guide, not necessarily the stopwatch.

Post by: Kelsey on 15/06/2012, 10:17 PM
Thanks Jeff, it's always great to get same, common sense advice pulling us back into line.

I've not had your experience, so I'm glad to take this on board - helps to explain what's going on in my own experiments. Certainly the undesirable flavours I've experienced in the past are elements I've associated with two things: an over abundance of centrals in the blend and shorter roasting times. I never enjoyed my popper roasts and it was only switching to the KKTO that gave me the results I was after.

That said, I've only done a couple of dozen roasts and have stuck to a really limited set of beans and blends that seem to react favourably to my treatment of them!

Did a kilo of Harrar tonight which was sourced locally.   I reckon I could smell the sweetness in the smoke....

Just got back from a quick trip to Ethiopia.  Was in a bit of rush doing other stuff, and I managed to buy 15kg without cupping  ???  , but at local prices I wasn't complaining...  Interesting to see green at less than 50% of the prices I was paying back home in Aust.

Picked up some washed and some dry process Sidamo, and some Yirgacheffe (which I found out the correct pronounciation is 'yeergacheffie').

The Sidamo washed was very uniform in size and looked a bit like a double sort I've had before.  The aroma from the green bean was amazing.  I suspect sitting in bags in a container in the heat for extended periods doesn't do the green bean any favours.

As you would expect, the dry process Sidamo looked much less uniform, but it will be interesting to see how it tastes compared to the wet. 

No problems with customs on the way back - Next time I'll use a bigger box...  :angel:

Post by: UNM on 16/06/2012, 09:45 AM
interesting comments on first to second crack timings.
When you start timing makes a huge difference (assuming you do time it). I often find a minute between first snap of first crack and rolling first crack. then can be another one to two minutes before end of first crack. there may still be one or two stray cracks after this, then it all happens again if you roast into second crack.

I tend to go by when the beans go exothermic, rather than by sound, and aim to slow rate of rise from about then on until end of roast. I only rarely log roasts at the moment, as access to laptops is restricted.

anyway back on topic- last night roasted some more Honduras coe. first snaps first crack at 11 min 30, pulled about 15 min just on cusp of second. Medium roast. resting for a week.

Title: Re: What coffee are you roasting this week
Post by: greenman on 16/06/2012, 10:06 AM
great discussion on time between first and second crack, when roasting on the corretto I always aimed for 4.30-5min time span but since switching to a drum roaster my times have reduced to 3min-4min resulting in enhanced flavour development :thumb:

Just weighed some bag end beans and, based on amount available and Brett H suggestions we have this evenings planned roast of:
100gram Java Ijen
64 Gram Guatemala COE
77 gram Costa Rica Tarrazu
25 gram Mexi Yeni Navan

To be roasted a tad lighter than normal - shooting for a fairly quick initial ramp and slow finish roast of
 first crack plus 10 degrees.

Guess which two bags I am finishing.
I still seem unable to finish a bag of CS coffee for some reason.

Maybe next week my CS bags will reduce. I only got 115 gram of yeni navan and 300 gram MM left. Pretty low on the Nyika too.

Mine is a small scale roast of...       120 gm Brazil Daterra Sweet Collection
                                                       100 gm Costa Rican Terrazu
                                                       160 gm Ethiopian Sidamo Mormora Plantation Gr3 Naturals
                                                       120 gm Sumatran Mandelhing Blue Batak

Beans were sourced from BeanGreen.

Roasted on the KKTO to a medium brown color. 3 minutes after 1st crack and cooled.

Will cup in 4 days time and reveal how it fared.

If i like it, it will be the mainstay of my bulk roasts for the restaurant.  ;)

This week I've done the following:

600g blend of PNG Blue Batak/Ethiopian Yirg

600g blend of Columbian Water Processed Decaf and Daterra Estate Sweet natural low-caf

600 SO of Finca Liquidambar

The first I forgot about and found it just starting second crack. Thankfully we had high winds and freezing temps as I think it slowed it down just enough.

The second two roasts went down so easy it's not funny. The decaf/low-caf blend seems to be just about the easiest roast out there, really hard to get that one wrong. Always even, roasts for about the same duration as my full-strength beans and tastes great.

The Finca Liquidambar was an unknown. I'd gotten it off BeanGreen because it was on special. It too roasted supremely easily, pulling at 2C at 23mins(!) but for a gloriously even roast.

Too early to tell about either, but I'd run out of beans so drinking them anyway. Even through the 'thinness' of these first couple of days, there's some really nice flavours developing in there. Can't wait to find out the final result.

Post by: Bean Flying on 07/07/2012, 09:37 PM
Worthy of it's own thread but keeping names and such out of it would be very hard. So much of the Australian grown coffee is average at best and some of it so below par against cheaper imports it makes the local industry look bad. :(

The MTE coffees I have either roasted or had as roasted by others have been better than the average and while maybe not worth all the premium (yes costs here are huge compared to virtual slavery) but certainly worthy of considering to drink/roast/buy.

Not sure if our couple of green suppliers can keep an eye out for us on the MTE front and or anything else worth considering? Also should note that some of the local production goes direct to end users too as roasted to make people feel good about buying local in spite of the short comings.

PNG Wahgi, Ministry Grounds Pre Blend and currently in the roaster is the Yemen Sanani Mocca.

The Sanani has pong to it in the roaster and I am not sure it is a good one :-| Smoke, moisture, chaff near silent cracks. Interesting roast to say the least. Due to the smoke and odors coming off I was running more fan and more heat between F & SC. I really need to move the ET probe too.

Roasting a secret special blend

This blend has a Yemen, PNG, Costa Rica and Ethiopian

The secret is in the prep
1) All beans were separately stabilized in low heat
2) Beans were roasted together but not pre blended
3 The roast was a stagard bean drop
The hard dry grown beans were started first
First the Ethiopian followed by the Yemen 30 seconds later
They were followed 45 seconds later by the Costa Rica SHB and another 45 seconds later for the PNG

Total green bean weight was 900 grams
As this blend is destined for the bean swap I won't reveal the amounts now

Maybe I should fire up again tomorrow and really play mad scientist for Bean Swap. My evil side says Robusta at 30-50% for lingering goodness >:D

Interesting option KK with different drops. I am starting to look at some post blending options/containers for 5-10kg lots and stick with roasting each as needed.

Roasted a kg of Sidamo yesterday afternoon.  It's getting so hot (mid 40's) outside I'm seriously considering roasting indoors.

I wonder if the missus would let me roast in the laundry....  >:D   Maybe some sort of hood with a pipe running up to the dryer exhaust vent high up in the wall (?)

I'm not a big fan of bright, citrussy coffee, so finished off the last batch and back to an old favourite.

1kg of locally sourced Harrar, on a hot and steamy 38degs evening.   Roasting while a C17 passes over the top of my house :thumb:

I finally got around to the Brazil Toffee Cerrado.

It's a small bean so I did 400 grams in the Behmor.

Preheat to 100 degrees, 1 P2 C = 21:30 minutes on the clock

1C - 9:37 to go, 247 degrees, a lot of cracking happening at 8:30, 250 degrees so cracked the door for a minute until 7:30, 230 degrees.

2C - 5:37, 225 degrees, left it to 4:50 when there was a lot of cracking happening, hit cool and cracked the door for about a minute and a half then closed it and left it to run it's cool cycle.

It's a bean you have to listen for, both lots of cracking were very soft compared to other beans, sweet smells coming from the roaster at different points, now just have to wait :)

Just finished off a couple of dedicated filter/siphon type roasts. 650g lots so very low power setting to manage but both to FC within about 20 seconds of 10 minutes (aiming for that) and coast to 1 minute past FC at 13.30 again within 20 seconds of each other  :)

And they were Ethiopian Gambella Naturals a truly horrible looking roast but oh so tasty so it will be interesting to see how it drinks in a few days.

The other after summoning up a little courage was some Costa Rica La Pira Geisha (only some cheap stuff @ $45/kg  ::) ) Nice and even roast but going in a few beans looked a little wonky and uneven and resulted in 5 or 6 Quakers and another few odd ones I pulled out by hand post roast.

Will pop the logs in the CCR thread with a little detail.

It's the first time I've tried using one - so still need to experiment with all the variables

Could probably have done with a longer preheat - plus I kept popping the lid open after first crack to inspect the progress of the roast - which stopped the roast each time I opened the lid

Still... Nothing wrong with what was in the cup!

1kg of Sidamo, this lot were the beans I brought back from the last visit to Ethiopia.  I'm hoping they will be much better than the other Sidamo I bought locally.

Also been playing with the pressurestat on the Urania. What I thought previously was set too high, was in fact just fine, and not burning the beans at all.  It's now set to cycle from about 0.9-1.1

Title: Re: What coffee are you roasting this week
Post by: UNM on 07/09/2012, 08:44 AM

I placed the beans in the KKTO and started with a 10 minute pre roast 65 deg C for 5 min & 125 deg C for 5 min = 10 min to stabilise or equalise the batch

[snip]
And 5 separate second cracks from 18 min to 23 min 

I controlled the roast by vision and smell trying not to over-roast the earlier cracked beans by allowing some periods of low heat  and allowing the internal bean temperature to take a lead on the speed the roast was progressing

On the last minute I removed the TO and left the beans agitating freely
This was done for the beans to colour evenly under there own generated heat

Conclusion
This was a challenge of a roast but I pulled it of by not panicking and respecting the beans by allowing them to come to there crack times in there own time and not over roasting the earlier ones


would love to hear feedback on this one.

without seeing/smelling/tasting I haven't a clue what the roast is like but sounds like it should be undrinkable.


why do I say this?

roast of over 28 minutes = baked

some beans are second crack plus 5 minutes

after roast is over they sit for a minute or so before cooling commences - prompt cooling is the norm.


Obviously my roasting experience and knowledge is limited and I have seen you refer to stabilizing at 65 degrees before.  Would be interested in how many other people do an extended roast at low temp to start - is this a KK only thing or is it common?

I sometimes go for a slow temp ramp to start, but never hold the beans at a single temp for any length of time

edit: oops.
For some reason my phone took me into an old page of the thread rather than the current one and I didn't notice how old kk's post was.

Would still like to understand more about 'stabilizing' beans  with an extended period at same temp though.

The stabilizing part of the roast is not hot enough to actually start the roast process
Normaly set at arround the thaw setting approx 65 deg Celsius
This makes all the mix of beans equal in start temp and moisture content befor the roast proper

It's best to use similar beans in a blend but knowing me I like to push the limits
The KKTO roaster in my observations just roasts well with beautiful results in the cup no matter if one goes over time from the accepted norm

I wonder if a simple chuck em in  a preheated 65 degree oven for 5 mins or so would be a suitable equivalent for non TO roasters.

I really ought to make a TO roaster though just for the experience. Still need to see a KKTO 'in the flesh' so to speak so I can work out a suitable alternative using the parts I have on hand.


And as I didn't get any replies to my request for advice on what to roast for filter, I decided to do two filter roasts - one Tanza Tec and one peaberry.  I need to get through some more of my stash anyway.

Brett, don't stress you are not missing out on anything extraordinary. I can think of many other coffees that would be on my bucket list.  Perhaps with this bean, it could be a case of urban legends growing legs.

Most of the southern Americicans are very easy to roast and at the same time produce unbelievably consistent roast depth and color. For this very reason they are well regarded by those new to roasting and perhaps this helps fan the fire of intense affection, albeit infatuation.

In general terms, Peru beans are quite mild and somewhat one dimensional in character being primarily used as blenders given the relatively high ratio of Organic - they provide an economic filler for certified coffees.

Yes, they develop plenty of choc and reasonable body which for most people will completely satisfy their personal requirements.

I have a few customers who own cafes who are lovely people from Peru. They tell me stories of proud Peruvian coffee farmers who like many at origin are very poor and take immense pride in their crop. For many years the Italian coffee buyers would swoop up vast quantities at low prices. Just like Mexico, they needed a way to secure improved pricing and Organic certified is one positive channel to help Peruvian coffee farmers.

Another interesting stat about Peru is that a good percentage of the crop are farmed and processed by women.

Today I roasted 300gm of Indonesian Sumatran Mandheling ' Kuda Mas', and pulled just on the 1st few snaps of SC.  I've been pulling my roasts slightly earlier after feedback from SS.  I think previously I was well into rolling SC.  :angel:

at the end of last week I did an emergency roast and roasted 300gm El Salvador Finca El Carmen which I had to start using 2 days post roast.  I'm sticking to SO at moment, and continuing to sample beans roasted a little lighter as above.

There's certainly a difference, and it's all part of the learning curve. :)

That sounds great Jonty... Although I've not had the original.  Clean and fruity I'd imagine.  Let us know eh.  :thumb:

I roasted equal parts (800g roast):

Columbian Bachue
PNG Kimmel Est
Brazil Dattera
Mexican Organic

Had to crack this one 24hrs post and its really lovely already.  The smell was to die for!

300g Toraja Peaberry
300g Sidamo Guji OCR Natural
300g El Salvador Finca El Carmen
all light roasts just after first crack
shared some syphon brews yesterday with a gathering of fellow coffee tragics. The Guji received lots of accolades--berries, stone fruit, juicy, clean and sweet:):):)

5 roasts this afternoon over a leisurely few hours with Jonty having a play with my roaster too.

Rwandan COE 500g Filter
Costa Rican La Pira Geisha 500g Filter
Nicaraguan ?? 1kg Roasted by Jonty. Nice even looking roast for a first bash at a different roaster.
1kg of some other rubbishy COE that some here reckon is awesome  :stir
finished off with 750g of Mysore Nuggets  (hoping Jonty won't get some for being home late  :rofl: )

Also dropped of were 3 cleanskin Reds so a good day  :thumb:

Lots of choices coming up in the next week or so.

Over the weekend I did a 400g/200g mix of Finca el Carmen and Ethiopian Yirg Gr 2.

Roast took 19mins to get to the start of R2C when it was pulled. Very even, quite happy with the way this one looks.

Ran out of beans today, so gave it a try. It needed the tightest grind available to me and a reasonably hard tamp for it to not be a gusher.

Really good stuff. Strong flavour, hint of brightness that I don't mind and lingering full-bodied chocish vibe.

Another kilo of Brasil Daterra organic.  This bean roasts so evenly... 

I might try it as a blend with some Yemen to add more body.

I roasted 600gm of Kelsey's blend today.

400gm Finca el Carmen and 200gm Ethiopian Yirg Gr 2.  Not the best roast I've done because I was wandering around the yard checking my new veggie patch and WFO (I know, naughty me), but fingers crossed that really was SC that I pulled them at around 19mins!  :rofl:  We shall see how they go.  I didn't want to test out 3rd crack if it wasn't!  :laugh:

108 gram Monsoon Malabar
40 gram each of Costa Rica San Isidro, Yirgacheffe Special Prep, Nicaragua Finca San Ramon Maragogype

Roasted quick to around 185, then ease off heat. Slow rise to 2c, but it still went off rapidly and dump 25 sec in just at rolling second.

 Looks uneven, unsurprisingly. Will taste how it went in two weeks

And you know what... I've never had it!  Yep, that's right... never had it.  Other than the Andy F's shop is there anywhere I can get this?  Not too worried if I can't but if everyone is raving I too want to dance like it's 1999!

Last Saturday fortnight I roasted the Peruvian Ceja del Selva that Jonty very generously gifted me.  I have enjoyed this bean in a range of styles from espresso through to French press and cappuccino.  Thank you Jonty.  What a joy this bean was to roast and the extractions from the espresso machine looked glorious... however: 

Brett, don't stress you are not missing out on anything extraordinary. I can think of many other coffees that would be on my bucket list.  Perhaps with this bean, it could be a case of urban legends growing legs.

Most of the southern Americicans are very easy to roast and at the same time produce unbelievably consistent roast depth and color. For this very reason they are well regarded by those new to roasting and perhaps this helps fan the fire of intense affection, albeit infatuation.

In general terms, Peru beans are quite mild and somewhat one dimensional in character being primarily used as blenders given the relatively high ratio of Organic - they provide an economic filler for certified coffees.

Yes, they develop plenty of choc and reasonable body which for most people will completely satisfy their personal requirements.

I am thankful to Jonty that I was able to experience first hand this bean and moreover experience and understand everything that Jeff has so beautifully articulated above.  Thanks guys... The journey continues.

19 mins has been about right lately.

Tonight did back to back of the above blend and a 300g Columbian Baucho, 220g Kuda Mas, 80g MM blend.

Both were pulled right as they hit R2C. In tonight's chilly weather, the first took nearly 21mins, the second 19.

Both looked nicely even and smelled amazing.

Which is a good thing, as I'll need to start in on them tomorrow!

Roasting. Going to pull out my magic dartboard for one of them, anything at or under 1kg has to go most likely for Espresso. For the others 500g of La Perla Geisha and I think 500g of Basmati Rice for filter.  :coffee2:

Desperate for fresh coffee after my return from Bali I turned to the popper today and roasted some India bold Mysore nuggets (true story) and some Nicaragua San Juan Rio Coco

Roasted the nuggets to a lighter style suitable for filter, and the Rio Coco closer to espresso roast - and cooled them both down with the cooling cycle from a hair dryer

Drank the Mysore coffee pretty much straight away as a pour over, and it smelt and tasted great with savoury / spicy notes on a buttery palate

And I'm sitting on the Rio Coco until I get my Rancilio Epoca espresso machine back - hopefully tomorrow - from having custom build stainless sides made for the machine, to replace the crapy plastic original ones that keep falling apart !

Hi All

Long time lurker, first time poster.

Just roasted a Kenyan Murangan AA+ to 1st snaps of 2nd crack in the Behmor. Good looking beans. Also an El Salvador La Guachoca roasted around the same. Looking forward to trying both!!

Currently on some Yirg and Colombian Volcans....... I'm fairly new to the roasting caper (15 roasts)..... I am so hooked it's not funny. Have just started thinking about a Lever for home thanks to a lot of what I've read on here.... you guys are gonna cost me!!

Post by: Fresh Coffee on 14/10/2012, 06:39 PM
Welcome to Crema. You have some nice coffees there, all quite different to eachother so a great source of appreciation of all things coffee. Why dont you also try some blending with them?

Re your comment re wanting to get into a lever machine.

No need to answer but....Why? Lever machines are the fad of the moment in some of the forums.  Suggest you think about what you are looking for in a coffee machine. There are lots of reasons people participate in the forums, and you should take note that they have a tendency to wind people up and then move on to the next "thing" of the moment.

Not that lever machines havent been around for a long time, but they are just another type of coffee machine and are very common in the southern parts of italy so they never went out of production in a commercial sense. They are however currently in vogue in forums amongst home users.

Juts dont forget however...they are just another type of coffee machine...nothing more, and nothing less, and the things people say about coffee machines in forums can be very seductive, and some people are really interested to experience the differences between some coffee machine types. others arent.....and just want a good cup of milk coffee. In which case, to go from a good pump driven coffee machine, to a good lever coffee machine, may not deliver the reality of the seductive picture that has been painted in the forums, especially if there is a vast cost differential in the change over.

If you already have a good coffee machine, think about it. What is it that you expect, from changing over to a lever? Do you drink black or milk, are you a coffee "head", or someone that just likes a nice cuppa, and.....can you taste the difference or do you care?

Just another perspective to help you along  ;)

Thanks for the welcome Attilio

I absolutely understand where you are coming from. I recently upgraded to HX E61 setup however I use a LSM Leva at work (if only we sold a single group) and there is something about the coffee from it. I also love the silence that comes with no pump, especially for that before work coffee that doesn't wake the kids. I just reckon they are a piece of art!! Don't get me wrong, the coffee I'm making at home with my current setup are some of the nicest I've tasted (both wife and I are hooked on the Yirg).

Roasted in the mighty KKTO, all done in 2 hours easy.

After a few days rest, i'm looking forward to trying it out.  :thumb:

Well today I roasted 1.2Kg of Jeff's Harrar Longberry, 500gms is a leaving pressie for my wife's friend.  Also roasted 600gm of that last of my Laos Dong Hua Sao (remember that one RM?).  So that leaves me with 1Kg of beans to play with the new machine.

That should last me a week eh?  Both roasted into 2nd crack, and in 600gm lots, that's 3 back to back roasts.  The KKTO never skipped a beat, and all 600gm roast hit 2C in under 20mins.  Sweet.

We're hoping to reproduce a similar tasting result. Would anyone from Melbourne like to taste and provide some feedback?

Appreciate the kind words.

We're proud to take those who are interested into the area and show them around, and we sometimes do machine demos on the Junior Extra dual boiler that I use for espresso cupping.

I think its a shame not to show people around, and you are not giving away any trade secrets in doing so. Its good for everyone and keeps the level of interest high.

There's a nice bag of Colombian Peaberry there for a bit of interest next week.

With the sensational weather, beer in hand, bloke needs to roast ;)

Taking delivery of Brendan's pickings from his recent Rwandan trip, we'll see how it fairs in the Behmor.  I did a 300g roast on 1IbP2C, with 1c @ 9:30 left and pulled it at 6:00min (suspect on the verge of 2nd crack).  So that gives it a roast time of 15min 30sec. 

I'll crack the bag in 7 days and work from there!

It was graded and screened on the spot while I waited!

I've had no experience with coffee from here before, so it will be interesting to give it a try. 

Here's a pic of some green in natural light, and a batch roasting for local consumption.

Forrest floor tannins - you should have seen the other beans I looked at before I found these....  You might call them the charcoal, rocks and floor sweepings blend!

I'm lucky I get to travel with the job, so my employer helps contribute to my green bean hoarding ;)

This morning, for a basic coffee appreciation session to be held this arvo, I roasted up the following:

Costa Rica SHB
New Guinea AA grade
Bugisu AA grade and
Indian Parchment AB Rob.

This was to exemplify to the participants, the progression of the amount of body in each of the coffees, from lighter through to heavier.

Cupping was by traditional method (not espresso).

Some of the participants were therefore also exposed for the first time, to the methodology of traditional cupping.

Fancy names of farms, plantations, origins etc were superfluous for the session, which was to educate the mind to the palate.

Roasting was in our professional sample roasting machine which I have nicknamed, "Il Tostino"......

....and operated...by me  :)

Anyway, one day post-roast and poured the absolute best looking doppio ristretto I've ever seen. 30 secs, 30mls, perfect viscous goopy start with an explosion of crema in the last five seconds.

Tasted great too, even today.

I'm struggling the produce the same result for the blend that I find really nice.  I am using the same ratio's:
- 50% Guatemala (Alliance beans)
- 25% PNG (probably Alliance as well)
- 25% Peru CdS

For the blend that I really like, both the Guatemala and the PNG has been taken to some 5-10 seconds after crack. I didn't roast up to that level last week as they start to oil by the first week. The cup that I've got from that blend was well rounded, medium bodied and I probably could even taste some chocolate notes and the balance of acidity was just right. Didn't get that from last week's roast as we've decided to avoid second crack.

Any ideas on whether I should roast it past second crack again? Is the oil-ing of beans a real concern? Somewhat in a dilemma now on what I want to do this week.

Eric.

The crack, whether it is first, second, etc. is just an indicator only - a reference point or marker, but in reality it will not mean that much as there are typically, say 12 - 17 minutes involved in a batch and the entire period needs to be considered as a whole, a.k.a. the profile.

I know you are seeking advice and recommendations, but the reality is you will need to roast plenty more batches, keep detailed notes and it's critically important to review and evaluate the variables and parameters used against the results and outcome in the cup - and how this changes throughout the days/weeks following a batch.

There is no silver bullet, iron-clad, definitive answer to your question as others will be roasting on apparatus that whilst might be of similar design, type or method, will most likely be actually quite different. The roasting device and how it is operated (including external cooling) will affect the cup more so that the beans used in your current early stages of roasting practice.

The only thing different beans will offer you is how they are responding (or tolerating) your roast technique (or profile) and that is assuming a VERY important factor - you can repeat each roast perfectly in terms of temp and time.

Oil is the essence of coffee flavor. You can google up plenty of comments about whether oil on the surface of a bean is a good or bad thing and of course it really depends upon the intention of the roast - how it is to be extracted or brewed. Roasters (and I'm referring to commercial) have varying opinions on when oil should start to appear on the surface of a roasted bean - if at all.

Roasting, like golf, is an acquired skill developed by practice and being able to learn, adapt and evolve.

Roast more coffee, focus on consistency, note everything you do differently and mark it as either a positive or negative improvement, feed it back into your loop so that you can understand why your roaster and technique produce the cup you taste.

It sounds like a daunting effort (but it's essentially about elapsed time and PATIENCE), however, once you have this understanding things will fall into place quite easily and you can start to exploit the diversity of bean selection and blending.

Put aside the blending for the moment. Grab an easy (or very accommodating bean) like the Peru or a Colombian, PNG or Brazil and focus on being able to roast this bean consistently (at least 5 times in a row successfully) as a SO to your desired taste and then start to introduce a degree of controlled variation on roasting the same bean (e.g. roast depth) to see how your roasting profile affects the cup. Then try blending.

Roasting as I post on the KKTO

A three bean pre roast blend of
300 gr of Costa Rica SHB E.P. Bandola
300 gr of Sumatra Kuda Mas
320 gr of Ethiopian Limu

It's a very wet day in Brisbane so I hope the 100% humidity won't have a detrimental affect

Yesterday I roasted 300gm of Kesley's "Finca El Carmen + Yirg = Win" blend which I really liked when I was trying to get to grips with my Achilles.  I'm just wondering how it will go now! :)  Roasted to 2C at and pulled at 14mins.  My KKTO was well warmed!

The I roasted an "bottom of the bag mix".  I cleared out my two boxes of beans, and put them in one big box, and in the process found a heap of leftovers.  So I roasted 180gm Java (CS bean), 180gm Brazil Sweet Naturals, 80gm MM chucked in for fun, and topped up with PNG peaberry to 600gm green.  Back to back roasting so this was one rather quick too, but 4mins between 1c and 2c, so hopefully it'll work out in the cup. ;)

Had a few cornels myself last night - courtesy of some Colombian FTO.

A., I returned almost a pallet of the LOLO branded Supremo Popayan recently (albeit a different bean to your Excelso) - as it appeared to have suffered heat stress at some point. To be honest, have experienced mixed results (some good, others not so) over the years from LOLO sourced Colombians.

Did 3 large back to back roasts
An experimental blend that I hope turns out ok / as I have added some Monsooned robusta

First roast comprised of
400 gr of PNG Kimel
400 gr of Costa Rica Bandola SHB E.P.

Second Roast comprised of
400 gr of Ethiopian Limu
300  gr of Indian Monsooned Robusta

Third roast and largest was an Indonesian / Sumatran Kuda  Mas
1 kg of Sumatran Kuda Mas
Did a whole KG as the roaster was hot and ready to go

Once roasted and cooled, all these beans were mixed well together in a clean bucket and bagged for a 5 day degas

Note - some of these beans are being gifted to a business associate so I hope my experimental roast is going to be to everyone's liking

Yes we do this every year at christmas. The pity will be, if the clients put it through an espresso machine or worse turn it into a lar taye, instead of infusing it or doing filter or a vac pot where they can much better appreciate the character they are paying for.

But of course its their money, and they can do with it whatever they like!

Kenyan AA Dorman (http://www.beangreen.com.au/product-info.php?pid147.html)

To my surprise, after chewing on one of beans right after cooling was complete, I was reminded of jackfruit. Anyone roasted these beans before and tasted something similar?

I did read the description and it says "...sweetness of tropical fruits, floral notes and grape, currant and wine-like characteristics..."

Am I hallucinating or did I really taste some 'jackfruit' sweetness?

Had a great time blending the previous bunch and the addition of 10% Robusta was surprisingly a hit with all who tasted.

Just did 250g Brazil Fazenda Rainha in the Hottop with my 3yo son. He loves roasting too! Have enjoyed other Fazendas I've tried around the traps so interested to see how this goes. Unfortunately it will probably be gone before it peaks at the current festive consumption rate.

Roasted up a kilo of an Ethiopian washed bean, but I can't for the life of me remember what it was...  Must be losing my memory with old age.  Next time I'll label the bag.

Anyway, was pulled just on second crack and is a rather plump looking bean with a nice tan centerline.

Thick body and nice taste - great as espresso and not really acidic.

Sitting on the plane now waiting to depart for Addis Ababa for a few days.  If I have time, I might grab some more to take home.

500g Columbia Santa Rita La Chapperal

250g Brazil Fazenda La Rainha

I enjoyed the Fazenda last time but think I over did it, so pulled it 5 degrees before 2c. Crunching the bean indicates I could have perhaps pulled it earlier. I'll find out next week in the cup.

ethiopian naturals... But as a dislike many beans from this area I did it a little different...




A: The mod to the TO makes it so much better.   Switch to override and no element cycling until I am ready.


B:  Just after RFC I added a few freshly cracked Macadamia nuts.




At end of roast, I had some fresh roasted  Macadamia nuts to snack on while bagging - Roasted beans smell great..


In a few days, I will see / taste the outcome  :pan

Last week roasted 800 grams each of the Colombian Volcan Galeres, Bolivian Green Mountain, Honduras Montana and Indian Monsoon Malabar in two hours using the KKTO. Post blended to 40%, 20%,20%, 20% respectively.

The week before it was 800 grams each of the Brazilian Monte Allegro, Costa Rica La Pala, Colombian Volcan and Ethiopian Sidamo, again on the KKTO.
Post blend percentages: 30/20/30/20.

Took all those to just before second crack, never into.

These amounts gives me 4x 500gm bags after each roast and whatever left over is for my own use.

Last week roasted 800 grams each of the Colombian Volcan Galeres, Bolivian Green Mountain, Honduras Montana and Indian Monsoon Malabar in two hours using the KKTO. Post blended to 40%, 20%,20%, 20% respectively.

The week before it was 800 grams each of the Brazilian Monte Allegro, Costa Rica La Pala, Colombian Volcan and Ethiopian Sidamo, again on the KKTO.
Post blend percentages: 30/20/30/20.

Took all those to just before second crack, never into.

These amounts gives me 4x 500gm bags after each roast and whatever left over is for my own use.


from what I hear maybe you should roast the MM 2 weeks earlier than the rest?

I tried an experimental Finca el carmen (400g) with Brazil Daterra Estate (200g).

Unfortunately both very, very small beans that seemed to progress through to third crack faster than I would've thought!

After a week it actually tasted ok, but the first impression was (in my wife's words) "It tastes like someone's dumped an ashtray into my cup!"

Some Africans that I just have to clear..... 


Who knows what they are, but will store for guests and visitors as I do not like them...


The ones from last week, have just started to come into their own...


YES, I know they are Africian's but have local Macadamia nut additive

How is the nut additive coffee?  Did you do a standard batch to compare and contrast?  Very interesting idea!!

Kids wanted to do a couple of popper roasts
120g x 2 (yield 200g)

If this proves any good then in the KKTO next time they go (not the kids)

     50% Peru Fundo Santa Martha

     30% Guatemalan Antigua Los Volcanes

     20% Indonesian Sulawesi Toraja Kalosi

1C 5:00-7:00mins  and 5:40-7:30 mins

Pulled both at S2C +10 sec

Both roasts 10:00 & 10:07mins each

725 grams of Finca El Injerto Capadocia Caracol, in the Coretto, pulled it at the first snaps of SC, small bean, roasted very consistently, very easy to roast.

Will be very interested to see how it comes up, paid over $30 kg for it, never paid this much for greens before and doubt I'll make a practice of it, just thought if I don't try I'll never know. :)

FWIW, tried it today, it certainly is different, good crema, lots of body, nice syrupy mouth feel.

The taste is certainly unique/different, I'm trying to identify the flavours, not having much luck, will try again later.

Would I buy it again? perhaps, it's certainly nice to try something a little different to run of the mill beans. :)

I complete a roast on Thursday night:

A blend that I have named the 'Merry Go Round' as a potential workable blend:

Brazil Yellow Bourbon 153g
Sumatran Kuda Mas 76g
Ethiopian Guji OCR 76g


Knocked off a couple of SO's today for a mate:

Indian Monsoon Malabar 305g roast
Sumatran Wahana Estate Naturals 305g roast  - god this stuff smells great as a green!

Both resting for 10days before I hand them over with a few other SO's - will inform him the MM needs another week at least as a minimum!

All on the Behmor with a 1IbP2B setting.

Hi Jonty
Did a similar blend last week
 Brazil Daterra Sweet Collection 50%
 Ethiopian Sidamo Cuji 25%
 Sumatran Kuda Mas 25%

I thought it worked well both as an ESP and MILK
I want to go darker next time than the roast I did but was definitely pleased with its potential

Last week, one of my fav's:
350g Brazil Joao de Campos
(350g) 210g Ethiopia Harrar, 140g Mt Raung Java
-Each roasted on the Behmor on 1P3C to the start of 2C.  Door cracked open at rolling 1C for duration of roast.  Will post-blend these two roasts and will start using it for espresso in a couple of days at ~10days post.

Also 450g Colombia Excelso on 1P2C to verge of 2C for cold process.

Last night:
300g El Salvador San Emilio on 1P2B to just after 1C for Aeropress at work.  First roast of this one.

Tonight:
350g Nicaragua Monteverde Fair Trade Organic Specialty on 1P2C, taken to first snaps of 2C for espresso.  Ended up just a smidge darker than I'd intended for a first roast but it'll play  :coffee2:.

My Yemen and Monsoon Malabar finally arrived this morning so will have a crack at those this weekend...  They cost a blimin' fortune what with the international shipping so they'd better be good  :)

I roasted some Rawanda COE from bean green, Lachim and I tried them today 7 days post

they were really bad, would not hold any crema,  even his dose testing throwaway beans were better.

 hopefully it was a problem with my popper roast, anyway we did 600grs at Lachim's house yesterday

I am hoping they will be better in about a week or so.

A welcome return today of an old friend, The BH Blend.  Some changes however from the original:

300g Tiger Mountain (thanks My Cuppa.. I love this!)
300g Flores Research Project (last I'll ever see of this due to not being a CS member)
200g Mexiqn Finca Cassandra
200g PNG Ondu (Thanks Neil from Ministry of grounds)

Today's roast was now:

125g each of PNG Organic, Mexican Pluma Organic, Indonesian Sunday Hejo and 200g of Tiger Mountain.  All four beans are from BeanGreen and once again their service and value is amongst the best I've ever received, for any product, anywhere!! 

The real bonus is that this tasted amazing straight out of the roaster.... Yeah, yeah, I know... But I couldn't wait and it was actually pretty good!!  All this for an average price of $10/kg green.  That's right $12.50/kg for coffee heaven.

Just had some beans delivered
So a roast on the KKTO is in order

700 gr of El Salvadore Finca Alaska

Roasted as a light up to the starting edge of second crack for this delicate bean for Lever espresso

These are the notes that go with this bean -

This is one of the stand-out coffees in any roaster's stash. In 2007, this farm placed #8 in the El Salvador Cup of Excellence competition. It is owned by Ernesto Mendez, who also owns Finca La Ilusi

Back to back roasts tonight: Ethiopia Gambella Sundried, Honduras COE Lt 15, and Indonesia Sunda Hejo!

I ramped the COE but pulled it at 13.5 min at the first sign of second crack, and I temperate dropped the Sunda @ first crack and coasted for two minutes, before ramping and pulling the roast a minute later

Still on the Gambella - ill let you know how it goes !

Post by: askthe coffeeguy on 26/03/2013, 11:01 PM

Still on the Gambella - ill let you know how it goes !

Well the sundried was a complete and utter debacle!

Some of it was hitting second crack while the rest of it was hitting first and I watched about 30 per cent of the beans turn to charcoal while the rest hadn't even come close to hitting second crack!

Managed to fill the whole house with chaff and smoke (actually I'm working in the bungalow out the back which is officially man space by night and woman and kid space by day!)

So apart from making a huge mess and nearly setting the roaster on fire - not much learned here except I think I'll steer clear of the sundried for awhile - very happy with the other two though!

Finca Alaska 600gr in KKTO

- Run hard on the full 235C after a 5 min drying cycle. Pulled just as a few puffs of smoke signalled second crack was imminent, and cooled in 25s to ambient.

- Result: Black tea, bergamot, grapefruit.

Great as a black coffee, needs maybe a darker roast for a single origin milk drink, though I think it'll benefit from blending if in milk.

Been a busy week, I have knocked over the following roasts:

1. Finca El Injerto - Capadocia Caracol -  resting at the moment (5/4) and for me and only precious me ;)
2. Indonesia Sulawesi Toraja - Kalosi   - drinking this at the moment (30/3) and pours like syrup.
3. Yemen Mocha Sanaani - also resting... Its a YBI wannabe  :(
4. Guatemala La Esperanza - Honey Processed  - roasted this for a bloke at work (5/4).

Reading the positive notes on Brazil Pedra Redonda, I reckon this the next cap of the rank or do I crack the Rwandan Cup of Excellence Lot 7 Buf Remera open?  Decisions Decisons.... Life is so tough hey!

Roasted another couple batches today  - one PNG highlands AA for espresso and one decaf, by special request as daughter wanted a coffee at 11:30 at night.
Decaf went straight out the roaster and into the grinder.  Who drinks a cappucino at 11:30 at night? Well now I know.

As I was making coffee anyway, pulled a short black of the decaf and it wasn't as bad as I expected. Fizzy, but not undrinkable.

I needed to ,I had to and I did. After much reading I roasted 650grm of Panama Gallardo Est. Giesha. With tongue in cheek I preheated KKHG to 170deg then loaded .Temp dropped and I added medium heat and low fan to give a gentle roast.With some heat only adjustments the beans reached ist C at 207deg in 10min and went gently to 223deg in 16min resulting in a beautiful CS8 brown,no 2ndC. From the sealed bag, while resting comes a sweet roasted aroma . Waiting for comments from my Son on flavor . Attached are beans in cooler.

Just finished roasting some coffee out on the patio. 22 deg and lovely and sunny.

Roasted a blend
Ethiopian Sidamo haile selassie gr3 naturals 200gm
Mexican pluma organic 150g
Ethiopia blue Batak 150g
150g png kimel peaberry

1st crack at 13mins, and pulled on first snaps of 2nd crack at 18mins. Looks good to me. Can't wait to try it.  Total roast was 650g so I did a nice long preheat at 150deg, and gave the beans 5 min at 150deg to level them out a bit.

Roasted up 1kg of Ethiopian; unknown which as I forgot to write the name on the bag when I bought it a while back...

Had a bit of a surprise while cooling it though.

I vac'd out the beans into the cooler, and was turning them over in the colander when up pops a little gecko, roasted medium rare by the look of it.

He was still in one piece so I'm guessing it was hiding in the vac pipe.

I dare not tell the missus or she won't drink the coffee ;). 

We'll see if there are any meaty flavours.

My advice is to not take anyone's comments too seriously as it really is not going to apply to your personal situation. The only way you know is to evaluate on a daily basis using controlled (as best as possible) methods.

Regardless of origin or specific bean, the factors that primarily influence the peak usage window, or best usage window for any particular bean are the way in which it was roasted (the profile), how and when it was packed (stored) in the roasted state, then it comes down to the processing method of how the farmer prepared the bean, then it is the age (or stability) of the raw coffee at the moment before you roasted it.

I have owned many roasting platforms and currently deploy 2 separate types - the same bean roasted using similar profiles on the different roasters yield different peak and before before periods. Why ? because the roasting platform uses different thermal transfer methods. It has little to do with the individual bean and more about how it was treated and stored.

Brilliant post Jeff!  Why was it then that the Baby Roaster when it was being taked up elsewhere boasted no resting time as one of the touted benifits?  Is it like saying 'you can eat a rack of lamb right out of the oven without resting it and it will taste all lamby and good'?
Title: What Coffee are you roasting this week
Post by: mycuppa on 17/07/2013, 10:42 PM
To be totally honest Brett, I never managed to get my mind around the science of how that roast platform was able to achieve immediate degas, particularly with limited airflow.

I have not had the opportunity to validate this concept and the engineer inside me has a natural sceptical view until proven, however I think Mark is 100% straight and honest, so I would not doubt or challenge the claim.

What I do believe is this............

Higher proportion of conduction roasting produces coffee that is ready early and does not last as long as coffee roasted with more (or total) convection.

You are basically breaking it down to whether you are cooking from the outside in or the inside out.

Wet hulled Indios can take 10 to 14 days to stabilize and they run for a very long time before dying.

Some dry or natural processed coffees can also need a similar period.

New crops can sometimes take a while to stabilize.

Brett,
I bought one of Mark's (CRA) first baby roasters; and have enjoyed a lot of roasting with it. Unlike certain resellers, Mark has always been honest, helpful and straightforward with this product. I do not read any of his online contributions as boasting, but interpret them as helpful instructions and explanations. He is very passionate about roasting. It is a great little roaster, and apparently a newer improved model will be available later this year. There are many advantages (and corresponding disadvantages) to this  roaster, but this sot of discussion should be in another topic.
As Jeff stated, there are many variables as to when coffee roasted on this or any roaster, is "ready" for drinking. I can do a roast and enjoy the coffee that same day. However, the bean does develop as it ages, and I find some sort of rest period beneficial. I do not believe the coffee roasted on the baby roaster, peaks earlier and deteriorates quicker. The roasting profile and the bean etc, etc play an important role in this.
I find that the same bean roasted differently, is ready at different times. I enjoy the spice of variety, and cannot be bothered being over analytical, due to time constraints.
One thing for sure, what applies to the baby roaster does not always apply to other roasters (and vice versa). The trick is to learn how to roast on your chosen toy, understand its limits, and then apply different techniques.
If anyone is skeptical of the results that are achievable on the baby roaster, buy one and taste the results for yourself.
As to when a coffee peaks, speak to your roaster!

Thanks guys!  Great posts and lots of good information to mull over.  I've never even seen a Baby Roaster but naturally as a slacko home roaster who often runs short of beans I've considered buying one.  The shorter rest time Is a very attractive prospect as a feature! 

To stay on topic yesterday I roasted 800g of the BH Blend and it tasted good e en as early today as a plunger coffee at work.

The Baby Roaster's principle is based on conduction and not convection.

Hence will, as mentioned above roast a bean that can be drunk sooner than others.
I would still recommend one or two days rest.
I have roasted robusta on the baby at the same time as roasting arabicas on the KKTO and coretto.
The cool thing is robusta is not required in big amounts for a blend so the baby roaster is perfect.
Robusta naturally needs more time to rest than arabicas, so the conduction roasting brings the degassing or all the beans into alignment.

On topic..

Last Saturday roasted 625 grams each of Bean Green's     
                                                                      Brazilian Monte Allegro

I have taken on pboard all advice thankfully. Roasted 600g Ethiopian Guji to226d oo 13/7 and have been drinking this for the last 6days. All espressos up till today were acidic. Today out of the Strega came a heavy dark beautiful cup , 13days post roast . Even though the roast was CS 8-9 the beans are now exhibiting a light shiny lustre . So I have been drinking my beans beforehand they have fully matured. Thanks to Cremas

I spent a very pleasant morning with Kevin and his Strega and CCR, loving both.

Kevin showed me some of his roasts while we were playing on the Strega and for me personally I thought they were a little on the dark side so when it came to approaching the CCR I made the decision to try and go for a lighter roast.

What you see has more to do with my preferences while being guided by Kevin's experience rather than Kevin being guided by me, just thought I should say if anyone thinks they are crap LOL

I took along the COE Honduras Finca El Filo and Tanzania Blackburn Estate - Pick of the Harvest.

We roasted the COE first, 1kg.
1C - 17:05
Pulled it at 21:00, didn't hit 2C

Tanzania Blackburn, 490g.
1C - 6:38
2C - 10:00 pulled it then as well, might have done with being left for another 30 seconds maybe.

Roasted up a kilo of Yirg that last time I tried using a 'normal' profile was way too citrusy, acidic and overly bright / flowery for my liking. 

This time it was done as a VERY light roast just on first crack.  It's destined for cold brew which I've finally got around to doing again since I have a lot of time on my hand(s) at the moment...

I found a place that has commercial 10ltr nylon reusable filter bags - for only $5 each!

I bought one 100 micron, and one 25 micron.

Running Colombian La Cacica AA and an El Salvador Finca San Carlos through the Behmor today.

Having been off work for 6 weeks with a broken foot, my coffee consumption has been surprisingly restrained, it's just too damn hard to go to the machine. Nice to have had some new beans arrive from Bean Green today though

And now the other kilo of MM is roasting as I type.  Kind of a funky aroma in the early stages of the roast, and it's one of my old favourites.

Re yesterdays roast - The Daterra organic is a really nice bean and always gives an extremely even roast. It's good to drink almost right after roasting.

2.15kg of Rwanda Buf Remera coe #7, dropped a little before 2nd.

2kg of Kenya Gethumbwini, dropped just on start of 2nd,

The Getumbwini coffee is amazing stuff to drink and being an estate coffee there is a lot of quality control and it shows in the cup. Ill give Brendon and Bean Green a plug here as you should get some to put through your roaster as you won't be disappointed.  :thumb:

The last couple of days has seen me throw a few roasts at the Behmor:

1. Two Panama Esmeralda roasts of 330g, 1IbP2B and pulled on 2C.
2. Three roasts of a blend of Brazil Yellow bourbon, Kuda Mas & Yirgacheffe. 2:1:1 for a 310g on 1IbP2B and pulled I to 2C.
3. The notes of melon... A 330g roast of Indo Wahana on 1 IbP2B and pulled on rolling 2C. I let this rest for 12-14 days before consuming.
4. Two roasts today of Kenya Thiaru Estate AAA, 330g, 1IbP2B and pulled into 2C.

All the beans above from our sponsor in BG or MG.

Just roasted on the KKTO - same bean as my last roast but slightly darker

1000 grams of Ethiopian Limu  ( roaster breezed through it in 18 min 40 sec but first crack was @ 15 min 30 sec )

Pulled and cooled on the start of second crack

The last and lighter roast is wonderful. This slightly darker roast should also be nice, again a little degas and it should be in the zone

Anyone else noticed that Wahana natural has a shorter life than many other beans?  Maybe it de-gasses slightly faster? I've been lucky if I get any longer than about 2 weeks out of them before they start to stale and it affects the pour.

I also picked up some Yemen the other day which the guy assured me was 'Ismaili number one'.  It was expensive compared to other bean prices here (about $17/kg) but I thought I'd give it a try.

A real small, manky bunch of beans, weird tan coloured, some insect damage, peppered with stalk, rocks and the odd unidentifiable bit of spice. I did a little manual sort myself prior to roasting. 

Roasted a week ago, slightly on the light side, and it's one of the nicest coffees I've had this year!  Very happy and I'll be going back to the spice market to get some more.

Also picked up a few kilo's of some sidamo and harrar but our customs friends at the entrance to the airport in Ethiopia confiscated the lot :(

Apparently 'it's not allowed' to export green coffee beans without an export license....

Title: What Coffee are you roasting this week
Post by: mycuppa on 20/10/2013, 11:14 AM
Not saying it happens in Ethiopia, but for many origins the best grades of coffee are exported and their domestic markets are serviced with the "rough" stuff.

Some South and Central American coffee growing countries have this challenge.

Generally, to get a decent coffee you may need to get out of the cities and up into the areas near farms and plantations.



Title: What Coffee are you roasting this week
Post by: borat123 on 20/10/2013, 03:34 PM
Yes I think it's true also for Ethiopia, but they do have the good stuff available too at about a 30% price price premium.

The good news is that prices have dropped about 20% since my last visit.

The rough stuff is priced for local consumption at only 70birr/kg which is about $3.80.  The good stuff, which I think is usually better than what I used to buy back home in Aus is 100birr ($5.45). 

I'm convinced that after arriving in Aus, the time spent in storage and shipping hasn't done the bean any favours.

I would say you are on the money with that theory........it's surprising how easy a green bean can degrade and I suspect quite a few people under-estimate this aspect because of the dreaded internet myths - which of course are always true.

what was Ethiopia like a far as buying a good coffee?

As far as buying by the cup, any street side cafe - all of the ones I've tried have great coffee.  The local's drink of choice seems to be a macchiato, with the milk poured first.

Re buying small quantities of green, there is one market that has quite a few vendors that specialise in coffee. At the moment it's still last seasons crop but within the next few months it will all be new crop again.  The problem is trying to get your green out of the country - not as easy as it used to be...

OMG - that's an old coffee KK. Wonder if it still has any life still left in it ?

A fantastic bean in it's prime - winner of a Golden Bean Silver Medal in the Single Origin class 2 years ago.

The grandson of the original family who setup and run the farm for a couple of generations actually lives in Sydney - he is now retired but takes a keen interest in all things Tanzania coffee related and makes the journey back each year with friends.

I understand the TEC Estate farm is now run by a Christian Brotherhood organisation - providing community support for the local residents.

It is a soft little bean (judging by the hand grinder ease) wants to run fast, had to up-dose with a fine grind to slow it down

I'll let you know how my syphon brew goes, should be ready by the weekend.

1. Mexican Triunfo Verde Coop, massive chaff thrower and I hope as the cupping notes say "Beautifully sweet with citrus and rich chocolate notes" come through!

2. I snagged 4kg of this gem as its been a while between drinks for me...  Sumatran Gayo Speciality Organic...  This is one super clean bean (on par with Wahana) and doesn't resemble a Blue Tak or a Kuda!!

Hi Jonty, the Mexican is gorgeous!   My wife who likes chocolatey coffee loved it and it hit the spot for me also.  Your right about all the chaff... There was so much of it in the KKTO cooling colander I resorted to doing the two colander and a fan trick to get rid of it!  I never had much success with the Wahana but I think I may have been drinking it too soon.  I remember tasting watermelon of all things.  Go figure!

Post by: askthe coffeeguy on 20/01/2014, 11:54 PM
bolivia green mountain and guatemela huehuetenango

both on the gene cafe with a 4min preheat to 200C then both roasted for approx 14mins with the temperature capped at 230C, then I let the machine do its own cool down - which is a bit suspect I know, because of how long it takes, but I compensate for this by pulling the roast prior to the onset of second crack, and then the profile just nudges second crack usually during the cool down stage!

its not fool proof but i have been able to 'set it and forget it' a few times with remarkably reliable results!

The huehuetenango especially was bloody superb but I drank it all in two days - and the green mountain is just starting to hit its stride now!

FYI both were roasted a week apart which seems to work ok coz I have prety much unlimited consumption while Im working!

Did a roast on the KKTO today the biggest weight I have done to date - 1300 grams
Just after I commenced roasting it started raining ( Actually pelting down)  could not hear a thing inside the roaster could not even the motor or agitator due to the noise of raindrops on the tin roof  ???

Anyway I just used smoke as a guide to approaching 1st crack ect then removed the TO and had a close listen to confirm

Todays roast was
600 grams of Guatemala Finca Santa Clara
200 grams of Guatemala Antigua Acate
500 grams of a South American Bachue - ( label is not good )

Total roast time was 22 min 30 sec with first crack at 17 min 15 sec
Overall a good looking very even roast

500 grams of a South American Bachue - ( label is not good )



KK - that would be Colombia Bachue - 18 screen Supremo.

Notes your can expect...... FYI only....

sweet notes of cherry and pear with a bitter sweet balance from dark chocolate undertones.
High grown, around Bogota in Cundinamarca, on the central branch of the Andean Mountains, with a perfect microclimate, the 'Bachue' is intense and complex. This is a bean well suited to a darker roast and consumed as a single origin. **

That sounds Devine

I can't hear any cracks in any case unless I lift up the oven.
I also use smoke for clues.
You,ll have to let me know how it tastes from that 1.3 kg batch. Wow.That's a big batch!

That weight was an accident
I intended to roast 1 kg and got a phone call - when I returned I added more greens and thought that looks more than usual ? Weight was checked at just over 1.3 kg
I was contemplating 2 roasts but I thought - Why not give it a go and see what it's limit is

Longer roast - for sure, but really nice and even

ok yesterday I roasted some:

Honduras Cup of Excellence Lt 15, which I had given to me, and some

Tanzania Villanova - which I purchased from GreenBean

Wasnt overly impressed with the Bean Green

Have to say that I wasnt overly impressed with the COE roast - little bit of discolouration, I put this down to  either the packet of beans having sprung open, and / or there being too much chaff in the chaff collector, which may have impacted upon airflow

But I'll resevre judgement until I actually drink the stuff!

But the Tanzanian was an absolute cracker!

I pulled the roast just shy of second crack at the first noticeable puff of smoke, and the colouration was perfect!

Not only that but Ive been drinking it for two days now - and yes, its only two days post roast - but its been absolutely knocking my socks off!

In fact Ill be roasting more tomorrow for schizzle!

wouldnt you know it - I tried to repeat the same roast profile on the Tanzania today and ended up over cooking it! 

So I redid the roast, dropped the temperature back to max 220C for 14mins then ramped to 230 for a minute - and bob's your aunty!

I roasted a batch of Sulawesi Blue (http://beanbay.coffeesnobs.com.au/ViewProduct.aspx/486-sulawesi-blue) which came as a freebie with the Behmor I just got.

It seems to have come up a CS9 on the old scale, and looks pretty consistent, so I'm hoping for good things.

Possibly unlikely KK as Andy has been supplying Sulawesi beans on CS for yonks. The Tana Torajah estates were the most common offered but Andy has been supplying the "Blue" now.
I prefer Sulawesi to other Indo beans but I'm yet to try the legendary Java offerings others have raved about
Title: What Coffee are you roasting this week
Post by: mycuppa on 10/03/2014, 11:13 AM
Sulawesi coffees have been around and available for a long time.

Quality has improved considerably over the last 3 - 4 years thanks to a determined effort by Tony Marsh and Jeff Nielson when they started major quality initiatives at origin in 2009 to educate farmers on improving their practices.

Bukit Marante is perhaps the most well know of the Sulawesi. There are a few Toraja's out there but some are not technically genuine.

Bukit Marante can be more complex and stronger than the majority offerings from their neighbors in Sumatra (Lintong and Mandheling).

When it's on the money - there are few coffees that can match it - one of my all time fave's.

$$ EXPENSIVE $$

Im back on the Zimbabwe Terranova from beangreen - and I cant get enough of this coffee

4 min preheat to 200C on the Gene Cafe, then 15min to first hint of second crack with max temp set to 230C

Produces a lovely brick red crema with earthy / cinnamon aromas, which follow though on a rich and creamy palate!

my first batch I roasted too dark even though it was only the first snaps of second crack but it came up too ashy for my liking so ive progressively pulled back on the profile since then and Im on roast 4 or 5 now and the parameters seem to be much better - as does the taste in the cup!

I like to know what everybody is roasting but I would also like to know more about what roast profile you used and how successful you think the end result was. Just in the  interest of knowledge sharing. I appreciate we are all using different equipment but still think it's a nice to know thing.           

Kenyan Gethumbwini 1.9kg in 1.58 out, FC at 9:23 @ 164c dropped at 13:23 @ 186c. (silver streak with artisan)

Really like this bean and pretty happy, can't wait to get it in the cup in 6 days, hmm 4 days, cup it tomorrow maybe  ;)

My mother once, and only once put them in the oven without sliting em.
She opened the oven door to inspect them and they promptly exploded, covering her hair with pieces of shells and a :o look.

Will have to give them a whirl and taste the results.
Reckon they go well with coffee.

Have you tried them steamed/boiled as well KK?

Chestnuts - I remember sitting down with my grandfather watching him roast them in a cast iron skillet / frypan with perforated (drilled) holes in the base roasted over  BBQ Coals

I too, use a skillet but I don't have an old fashioned open BBQ so I settle for the webber first but if I couldn't be bothered then I use the trusty gas BBQ

I'm of Sicilian background and My wife comes from Northern Italy and she's used to boiling them and you squeeze them and it comes out like a paste....freaked me out the first time I saw it.

Aaaah Yes, very fond memories of my time in Harrietville, the little fuel stop town right on the base of Mt Hotham. Anyway, my local mate Greg knew a field up the back of the town dump where a dozen or so very burdensome Chestnut trees grew. Course, all the locals knew about it, but that didn't matter, there were always plenty to go round.

Roasting? Just like everything else, threw em in the Furphy... (Cast Iron Camp Oven for the gen w, x, y, and z) gotta love the Ol Furphy. Actually I'm sure one of my boys 'discovered it' in our recent house move. "Hey Dad, What's this rusty Ol steel bucket used for?"  "Hell son, that's me Furphy... You take good care'o that... It's a classic"
It'll take me another ten years to find it again now... :sigh

So after my last roast, KK and Galumay suggested I might want to try roasting a little further into 2nd crack as on my initial attempts on the Behmore I had been a little scared of fires, and had stopped the roast a bit too early.

This time I waited until 2nd crack was well under way before hitting the cool button.  i'm not sure if I haven't gone too far in the other direction.  Constructive criticism is appreciated.

Bean: Colombian Volcan Galeras Supremo
Roaster: Behmore 1600
Profile: 1lb P2 B
1st crack around 12min, and 2nd crack well established when the roast was stopped at 17 mins exactly.

Unfortunately they have developed a little bit of an oily sheen, and have a slight bitter twang to them. Drinkable with white stuff, but a little off putting as an espresso.

A minute or so less on the behmor next time. I really should be keeping records of these roasts, but as I only have dribs and drabs of quite a few beans I'll probably wait until I have a decent amount of one so that I can get a better feel.

I've just roasted the same beans again. Same profile on the behmor bit totally different roast characteristics.

This one started first crack around 9 minutes into first roast and I had to hit the cool button after just over 12.

No idea why it behaved so differently and won't get to as that is the last of that bean.

Looks better than the last roast so will hopefully taste better in the cup.

I wish there was some way to cool the beans down quicker as you hear the 2nd crack snaps for a while after you have hit the button to cool them.

Just stepped out of the roastery, I love that lingering smell of roasted coffee.

2.5kg Costa Rica Don Mayo
Charged at 150
FC at 7:30 @ 160
Dropped at 12:47 @ 176

Despite what appears to be quite a hard tight bean the Don Mayo likes to suck in the heat, sure if I had a moisture meter it would have read quite low.

2.5kg Ethiopian Sidamo Guji Berta  (like this as a coffee)
Charged at 130
FC at 10:53 @ 169
Dropped at 14:52 @ 186

Played with the profile on this bean to see what else I could get out of it.

Happy roasting

I did a couple of batches of Peru ceja de selva today. Two because we had a power cut just after first crack had finished and the beans were very light in color.

Will try them but not expecting great things as espresso.

The 2nd batch came out much better looking even if I did do them on the p3 setting by mistake.

Just munching into some Sumatran Wahana Estate beans I roasted on 6th April.  Been a while between midori drinks ;)

A bean that needs such a fine grind, it would be almost be turkey grind to get the shot time in the zone.  Lovely bean and I must say of the 7kg I had, I think only 500g remains.

I've just finished a 4 week stint on Panama Esmeralda from BG, the last of the 2kg lot I had.

Later this week will be a bag of Rwanda Musasa, got a small stash of this left (<1.5kg).

I'm a little early using these beans but I've run out of everything else so as beggars can't be choosers I decided to use the underdone beans. In a latte it was surprisingly good. Good enough that I will give it a go as an espresso later.

I picked up some Huehue from Brendan (Bean Green online), for my customer blend this month and I roasted some as an SO, its the Guatemala Huehuetenango Rio Azul Co-op Organic specifically and its come up quite nicely. Its got enough in the cup to enjoy as an espresso and it just manages to hold its own with milk.

Post by: borat123 on 31/05/2014, 04:19 AM
I found an old vac pack bag of green Sidamo from almost a year ago, so tried some profiling and a bit of a home cupping...  After reading an article on 'stretching out the roast', I thought I'd see how things went trying to use a home roaster as a sample roaster.

I was using a much smaller batch size of only 300gm, which needed a lot more attention than the usual 1kg in the KKTO which is just set and forget until first crack.

The first roast was just to get a bit of a baseline so I let it run all the way through to 2C, at around 215deg.  The ramp was kept to 15degs/min until approaching 1C.

(http://i199.photobucket.com/albums/aa143/ss_0001/Dark.jpg)

Second one used the same ramp and was pulled at about where I'd normally do it for this bean, between 1C & 2C, at around 207deg.

(http://i199.photobucket.com/albums/aa143/ss_0001/Medium.jpg)


Third was with a slow ramp (10degs/min), and pulled much earlier for a lighter roast at 203deg.

(http://i199.photobucket.com/albums/aa143/ss_0001/Light.jpg)

And the results...  I've got a bit of a head cold so probably not the best time to be trying to cup coffee, but anyway the results were surprising in how good & bad the profiles were compared to each other.

Roast one was pretty bad, although the colour of the beans were dark, it didn't look ridiculous or spotted with oil. The taste however was just like a morning cup of charbucks. Ashey, smokey, burnt and overall nothing good about it.

Roast two, which is how I would usually have roasted this bean, was underwhelming.  Drinkable, but flat, bland, perhaps muddied -as in no particular taste of any note stood out.

Roast three, which I thought would have been too light, was actually the best of the lot.  Clean, 'crisp', an immediate fruity sweetness on the front of your tongue, a bit like honeydew.  The cupping taste was so good I think it would make a nice filter coffee.

So the lesson learnt is I should be doing more cupping rather than just adjusting the roast based on taste from espresso. (And I have to get a box of cupping bowls - the mugs are a pain in arse to get the spoon in & out of...)

Borat - I am not at all surprised roasts 1 & 2 would not be suitable at all for cupping based on the batch graphs displayed. Regardless of how well they may have been roasted, for cupping that are just too dark.

Although, put them through an espresso machine, add some milk and the results are likely to be quite different. I'm predicting #1 will still have some ashy taints with bitter-sweet cocoa, #2 might be OK, or a tad sour (unless you let it develop for 10 days) and #3 will make a nice juicy double rizzi (no milk).
 
Roast 3 would be in the ballpark for what to use when cupping - even stopping the roast a bit earlier around 1st crack, depending upon the bean in question.

Hi Jeff, thanks for the info.  I've finally booked myself into some cupping & roast profiling training next month, so thought I'd do some 'homework' before I head off.

I've been doing some reading and now am even more confused than before I started..

When cupping for flavour (rather than defects), and if I have a profile that produces a great result when cupped, is it translated just to take into account the move from sample roaster to a larger roaster (say a 15kg)?   

Or is the profile also changed because it was intentionally light to suit the cupping?

Cheers from sunny Dubai (it's 42 already and Summer is only just starting..)
Title: What Coffee are you roasting this week
Post by: mycuppa on 31/05/2014, 06:41 PM
Typically, sample roasters do not have the same precision in terms of controls as a quality commercial roasting platform, e.g. they have heat and constant airflow, so you can't really do anything exotic on a sample roaster by playing around with agitation or airflow speeds.

The methods used to roast on the small sample roasters are quite basic - a heat source and time (duration).

Generally, when driving a sample roaster you run to a simple procedure of heat on at level X and for Y time, or until crack or other distinguishing mark in the roast process, etc.

I have some personal opinions about the use of sample roasters in a commercial sense. Yes, they are a nice small and easy to use tool when evaluating a bean, but the heat map (stamp or signature) of a sample roaster will be dramatically different to something like a 30 - 120kg roaster - the coffee will taste completely different, unless of course it is from the same brand. 

What we also see is that the majority of sample roasters have high levels to conductive thermal transfer whereas many large commercial roasters use higher levels of convective (air).

I see sample roasters deployed in these sophisticated lab environments at some joints here in Melbourne and tend to have a quiet chuckle to myself - there is no way something on that will mirror the big unit outside in the warehouse. The true test is when the coffee runs through the production machine.

We often have brokers wanting to send us 200g of green beans to evaluate. My response is......no, I want to buy a 60kg bag so I can run a few batches through the actual roasting platforms that are used for customer coffees.

In terms of roast profiles. The stuff you roast for cupping will generally not work so well through an espresso machine - sometimes it will for black (especially fruit coffees), but rarely for milk-based espresso.

Flavor is the by-product of extraction/brew efficiency+effectiveness - rather than from the way it was roasted (well, that's not true technically, but conceptually of course). Flavor is the oil being released and this needs to be carefully matched to the extraction or brew method - so the roasting profile needs to be considerate of that brew or extraction type at the time of roasting.

Things can easily go wrong during roasting to make it "difficult" or "challenging" to release the oils from the bean. All sorts of problems such as internal or external scorching, baking, stalling, lack or adequate airflow, too much airflow, inconsistent rate of rise, too dark, too light, etc.

In terms of cupping for flavor versus defects - I'm afraid this is one and the same - an optimum value (efficiency) existing for the brew method of cupping (which is different to espresso, or filter) - this is where the flavor AND the defects will be most pronounced (or detectable).

Yes, there is a place for sample roasters and it's typically in the green bean evaluation side of the business.

Taking a profile used on a sample roaster and then transferring the same concepts to a commercial roasting platform does not work. Each roaster has it's own quirky heat map and this needs to be fully understood as to how it translates to the roasted bean result.

It's almost Ramadan - just few weeks to go......which will make it hard in summertime over there in Dubai with longer daylight periods for those of the faith.

Actually for a number of reasons it's a good time of year to take a holiday back home. Many expats disappear about now for the entire school holidays (about 2 months).  24hr oppressive heat, and not being able to eat or drink in public during daylight hours can be a bit of a pain, but as a guest in someone else's country, you just adapt and get used to it.

One good thing at that time of year over here are all the sales in the shopping malls, and the good buffets in all the restaurants that start at sunset.

Re profiling, great post thanks.  So to summarise, a sample roaster is good for evaluating green to make purchase decisions, but developing profiles to get the most out of a bean is better done on the production roaster itself.

So for example if roasting an unfamiliar bean on a Giesen 15kg, how small a batch size would you work with to develop a profile?
Title: What Coffee are you roasting this week
Post by: mycuppa on 31/05/2014, 07:50 PM
I have a Geisen 15kg but it would operate a bit differently to others - there have been some changes I made to my roaster.

Gas pressure and type of fuel are also a consideration as is the flue design for the exhaust, or if afterburners are used.

Geisen, in my opinion, has a bad airflow design just like probats in that it becomes restricted as the chaff buildup occurs between the detailed cleaning events.

Of course, Geisen would argue they have compensating pressure systems that help with that problem, but the fact is they don't work so well and the operator needs to be aware of these conditions over time.

I don't roast anything below 10kg charge weight on my Geisen for different reasons, but other roasters may go down to 5kg.

When you drop to low values of charge weight the dynamics of the design fundamentals of the roaster are at odds with the roast process, e.g. surface are conduction, airflow, air volume, bean agitation, etc.

Are you roasting, or planning to roast on a Geisen 15kg in UAE ?

Post by: borat123 on 31/05/2014, 08:05 PM
No, nothing yet but a certainly a possibility at some point in the future.  I remembered one of your earlier posts mentioning you had a Giesen, so was interested in an unbiased opinion as to how they are.  I'll get to play with a bunch in the US in a few weeks, and no doubt they'll have their own views also.

Large bottled gas is in use over here for smaller scale operations.  No need for an afterburner but the municipality does still have some requirements..

Ah - OK.

One of the things we might look at in 2015 is a roastery in Abu Dhabi via a joint venture.

Title: What Coffee are you roasting this week
Post by: borat123 on 31/05/2014, 08:23 PM
Country risk is pretty big, in my opinion, especially with the LLC company structure requiring 51% local ownership...  Memorandum of association & side agreements to set up to try and protect against future claims on past profits or sale price by the 'silent partner...  Basically there is no tax but you must pay the partner a set annual fee to be able to run your business. 

Re Abu Dhabi, a bit more traditional than Dubai, which I think has the greater expat population. Shopping mall cafe's are almost without exception franchises of the large chains, such as Costa who I believe import their roasted beans here from India....

We have been roasting  - via our Melbourne client - for UAE for more than 2.5 years already, including Qatar - many tons have been sent there.

This was about localizing the product and growing the specialty segment, which may also occur in Singapore as both areas are in need of some focus.

Our client already has a well-established business model in the region.

Nice!  You're allowed to mention KJM and CS.  It's an outstanding blend and also an excellent forum.  I've not been a member there for some time but check their recent posts every now and then in case I miss something like a Breville release (I missed the drip-thingy and the Oracle).  We don't get visited by Breville here because someone, and I'm not going to mention any names, accidentally called a Breville person who is a coffee genius.... a Teapot.... accidentally damn it!

On CS we're referred to as the 'boat-rockers' I assume because our members are allowed to have differing opinions to the sponsors and the Mods (some mods, not me... I'm unforgiving and ruthless). 

In short (too late)

Any resource that's good for coffee is good for Crema including Ebay, Gray's Online etc.

Back on topic I roasted my BeanGreen latest on Thursday, batches of 500 grams of:

Monsooned Malabar (too soon to tell)
Peru (awesome already)
Bali (awesome but too soon)
Rwanda (oh this is good... Chocolate orange.... Mmmm,mm)

We will have to agree to differ there, IMO its not a forum, its a commercial site. Many of us who were forced off their site, or banned like me ended up here - an actual public forum.

Anyway, thanks for the reminder of the original blend name - KJM, yep that was the basis for my 'Kofeh Yo' blend that I sell. Aside from the consistency I get while using varying beans from the specific regions, it also means I can roast a bean from each of those regions as a SO so I always have some new and interesting coffee to try - without changing the basis of my blend.

Yesterday I fired up the KKTO and roasted a 1 kg blend

600 grams of Indonesian Kuda Mas
400 grams of Colombian Bauchue

I feeling that this blend will be a double choc hit to the palette

Exactly what Brett says x2

Exactly what Brett says x3

I don't know of any other commercial roaster who gives his thoughts and advice as freely as yours.
Thank you.

Off topic, Cosmic Couple, I will also be playing with a few of Coffee Brushes profiles as per stretching out 1st to 2nd crack, stretching out drying stage as well as prolonging 1st crack and do some cupping.
Anyone else want to give it a go, we will look forward to your feedback.

Today on the KKTO I roasted a favourite in KKs household

1 Kilo of Colombia Bachue - 18 screen Supremo.

Just on the 20 second mark into 2nd crack

Care to share your roast profile on this bean KK?

Hey Gary you must remember this is a 1 kg batch

Colombian Bachue 18 screen

Roaster at full heat for 10 min on warm up
Drop beans in
Run at full heat - 250 deg
First crack normally at 13 to 14 min
Start of second crack at 18 to 19 min

KK

THanks for sharing your profile KK.

I run a 625gm Supremo batch to produce just over 500 gm which fits into a 500gm coffee pouch.

200 deg preheat.

230 deg til first C at 13-14 min. Stretch out first crack by burping.

Dump beans just before or first snaps of second at 16.45-17 min.

Next roast day I'll try and extend 1st to 2nd and evaluate.  ;)

Did a bitsa roast last night as my first back after the temporary coffee ban in the Eggie household. Finished off the last of my Colombian Volcan Galeras Supremo and topped it off with Peru ceja de silva.

Not got a lot of confidence in how it will turn out, but we shall see in a few days.

She took a few sips of a white coffee I had again this weekend and liked it. Not enough to want a whole coffee to herself but that was all the encouragement I needed.

Now to see if I can wait a week or more to have a crack at making a decent coffee out of them.

Roasted 620 gm each of Costa Rica Rio Negro RFA
                                        Brazil Monte Alegre Estate
                                       Rwandan Inzovu Co op
                                        Colombian Hacienda Curazo Supremo

to produce 2 kg roasted and post blended.

The Brazil, Rwandan and Colombian was roasted on a longish profile.
The Costa on a more shorter steeper profile.

Beans are from the current crop from Bean Green.

Have to say I like the cloth bags they came in. Easy to re tie. Great for recycling into other products too.

Today I just finished roasting on the KKTO roaster

1 kg of Guatemala Arabica Antigua

Quote
Guatemala Antigua Coffee

One of the finest Guatemala coffees is Guatemala Antigua, which is distinguished for its complex flavor and hint of cocoa.

Antigua is known to exhibit the typical Guatemalan coffee qualities which include a full body (heavier than the typical Central American coffee) and spicy flavor that is often very rich, even velvety. An ideal coffee-growing soil and climate is found in the Antigua region, a valley surrounded by three volcanoes.

This is my current corretto setup. Works great, but setting up and cleaning afterwards is a nightmare. :tearhair:

Sulawesi
My normal roast batch is 350g. But I'm starting to roast for other friend, so trying to bump up to get 2 x 250g roasted in a session. Did 620g Sulawesi. Ended up over & under roasted, with first crack happening as low as 195 stretching towards 210 degree.  :P So 2x250g is not possible.

Ethiopian Gambella
Lesson learnt and for the next batch I reduced the batch to 500g Ethiopian Gambella. Result looked ok, though the sundried beans aren't the prettiest.

Look forward to tasting them and that means another 7 days of waiting. =/

Tonite I sold 8 bags to a group of CBA executives who had been on one of our cultural tours - i have started supplying ground coffee for the plungers and they went wild about it!

Now busy roasting to catch up with the production for my normal customers as that cleaned me out!

I have borat123 and was a pretty good read, gave me some extra confidence that I was on a reasonable path as  I already more or less roasted that way. Combination of learning off Mark Beattie from Coffee Roasters Australia, Coffee Shrub crew (turning point in my roasting style chatting with these guys), Kees Kraakman stuff (more great reading) and doing a Boot Camp Coffee course. Also throw in all the great info shared online from guys like BeanFlying and KK early in the journey.  Add in the few hundred kilos of roasted mulch in my garden beds  ;D and that's my coffee roasting journey to date, still plenty to learn and understanding the nuances of all the coffees out their and how seasonally they can change is a huge endeavour and most enjoyable.

If that's the one from Beangreen, then he is in for a real treat. A great bean for lighter roasting, I have found nothing much to my liking going more than 1min past the end of rolling FC. Around 13.5min total time.

I had a plunger of it the other day and it was very enjoyable.

Seems no one payed attention to your post KK.

That's a great looking roast. The Supremo is an easy bean to roast and great in a blend.
Heck, it's even great as a  50% base to a blend if anybody wants a bold tasting coffee.

Sorry for the delay in relying. Been out all arvo and on way out (dancin') now.

So, quick answer:
Lake Tawar was the first roast (2nd pic) pulled at 185 roaster temp not BT.
The Tanzania KVCG was pulled at 182 deg and is the darker of the two.

Today on the KKTO a special G20 roast
Brisbane City in in lockdown today and the CBD people have been granted a public holiday because of the G20

That makes it an opportune time to roast a 1 kilo X 3 bean blend

400 grams of Guatamala Arabica Antigua
300 grams of Sumarta Kuda Mass
300 grams of Colombian Suoremo

Should be a nice blend

That's three rather pricey batches there bcspark, to do in one session.
You must really love your family to share.
At $65/kg green and having some in stock myself, I'm interested in how they turn out. Profile temps etc.
Are the three batches being roasted similarly or for different brewing styles?

One of my sons is our benefactor . Completed 2 batches both 17 min 230degree cs9 . We three of us enjoy triple restretos or macchiatos . As explained by supplier the bean was easy to roast and I found this to be the case . I have the profile logged on my tablet but cannot place on the forum due to inability to do so.Useually I could call on my eldest to help with task but he is fully occupied as spouse and health provider.

Knocked out a kilo of PNG NCT Organic, followed by 600g Indian Monsoon Malabar.
Both looked the goods, taken just into start of 2C.
PNG 1C @ 13;30 & 167 deg 2c @ 17:44 & 188, pulled @ 18:09 & 190 deg.
MM 1C @ 9:50 & 170 deg, 2C @ 13;00 & 185 deg, pulled @ 13:25 & 187 deg.

Of course I'll be letting the MM sit for some time, but might have to dip into the PNG in a day or two as stock is low.

No disrespect meant to the roaster as I have some of his coffee now and it is excellent, but those Blue Batak beans look horribly inconsistent. 

Is this just one of those beans that looks ugly but tastes good?

It's that time of year again when the middle east version of disney land and it's associated markets open up for the cooler months.

Fresh from the Yemeni spice vendor's markets are a few kilos of unidentified beans, with faces that only a mother could love...   Broken, split, a few blacks, the odd peaberry, a few insect damaged and otherwise slightly pale looking beans - pretty much the same as last year, but perhaps a slightly larger screen size.

The roast took a fair bit of heat, and I normally take these a little longer towards 2C than I otherwise would.

The result....   Unbelievably good.  As espresso, it pours like chocolate, thick body & smooth, muted acidity, sweet nuttiness with some stone fruit.  The mottling in the cup looks like a work of art!    With milk as a mac, it was ok but IMO a waste of a great SO and not well suited anyway.

Retail price was 50 dirhams a kilo, which is about $16 in real money.

Just opened a 2yr old vac packed  brick of Daterra Yellow Bourbon, and it still smells like fresh crop.

Spent the evening last night doing 1/2 dozen 100gm roasts trying to tame the sample roaster... This thing has so much heating energy compared to a normal roaster - it's a real struggle just trying to get a roast longer than six minutes!

More cupping fun today.
Title: What Coffee are you roasting this week
Post by: cosmic_couple22 on 29/12/2014, 07:31 PM
Feel your pain borat123 the sample roaster never translates a profile to the big roaster. Is it halogen or gas?

Was the vac packed coffee fridged as well or just dark and dry spot?

Chester

Title: What Coffee are you roasting this week
Post by: borat123 on 29/12/2014, 07:51 PM
Just kept in a cupboard.  IMO the vac packed bricks do a great job of suspending the coffee pretty much as it was the day it was packed.

The roaster is a two barrel gas - not for profiling, but just testing samples.

It has digital temp setting and burner control, but since the probe is measuring env temp it probably would have been better with a gas flow gauge and a bean temp probe...

Early days yet but definitely a learning curve as none of the 'normal' numbers I'm used to make any sense on this one..
Title: What Coffee are you roasting this week
Post by: cosmic_couple22 on 29/12/2014, 08:07 PM
So you only need to slow it a little bit, what are you aiming for  yellowing at 3-4mins, FC around 7 and finishing at 9-10. 
Sure it won't take you long to be all over it. Gas gauge would be good so can you retrofit one?

Chester
Title: What Coffee are you roasting this week
Post by: borat123 on 29/12/2014, 08:23 PM
Yep, FC @ 7, then dump at 9-10, agtron 58, is pretty much SCAA standard for a sample roast.

What I'm finding is unusually low drop temps, high airflow and low gas settings are needed to achieve the 'standard'.

Definetly want a gas flow gauge as the flow knobs are very imprecise and the same position on both barrels can result in large differences in heat.

I need to do some more playing and cupping before deciding if any other mods would be worthwhile.
Title: What Coffee are you roasting this week
Post by: cosmic_couple22 on 29/12/2014, 08:39 PM
Don't think that approach is anything unusual really borat123 with such small batch sizes, I would see it as the norm from my own experiences, even translates that way when I do small batch on the SilverStreak.

Keep us posted on your results and photos of upgrades.

Planned them with the roast designer V2 (check the calculating DTR thread) then roasted them using the coffee sweet software on the SilverStreak and the numbers really stacked up (will do some more testing but impressed thus far)

I did a 500gvroas in the KKTO yesterday of:

180 Yirgacheffe Gr2
180 Sumatran Toraja
140 Columbian Huila

Looking forward to this... I loved the mocha Kenyan blends I'd did prior to Christmas but I'm all out of Yemen.

Had the final roast on the old TO on Monday.  Roasted it a bit lighter based on what I picked up from Cosmic_couple with his hipster roasts for a change to my usual 2C roasts. :)

This was a 4 bean blend (Attempting to use up my leftovers)

30% Brazil Daterra Estate Opu 2 Exotic
30% PNG Wahgi AA
20% Tiger
20% Indo Sumatran Mandheling Kuda Mas

Roasted 750 grams of Uganda Kisoro in the Coretto yesterday, stopped the roast @ the first snaps of second crack, nice even roast, approx level 9.

"Uganda Kisoro AA. This high grown Ugandan Arabica is washed but not polished and then screened to a large AA size. In the roaster this is easy to roast but expect plenty of chaff. In the cup it has a subtle acidity and heavy body that made a great double espresso and a syrupy ristretto. This worked best for me roasted to a CS10 depth where the cocoa range of flavours dominate."

The Rwandan is a lot lighter, the picture just turned out dark for some reason.  I pulled it a bit earlier than usual but that's what happens when your juggling the kids and roasting! lol.  I've been trying for a few lighter roasts anyway after chatting to you, so it will be interesting to see what they are like in the cup. :)

Roasted a few days ago,  Yirg Kochera for some forum members  ;), Nicaragua Lupululo which is a great coffee and nice to roast.  Finished with another 2kg's of the new bean on my shelf - Costa Rica Granitos de Oritz, loving this coffee, very different, with amazing flavours of toffee and golden syrup combined with a nice buttery mouthfeel.

A perfect afternoon in the roastery was had, with the added new water views due to the flooding.

Crickey Lacheim... That one is threatening antique listing.  How is it??

I've roasted a special blend of 300g Sumatran with 200g Yemen to just on 2nd crack in the KKTO.  Only 3 days ld and couldn't wait.  A bit fresh but so good already!
Title: Re: What Coffee are you roasting this week
Post by: Lacehim on 02/03/2015, 10:44 PM
It's resting still.  And oldie maybe, but still look ok, and kept in a cool dry place.

The Honduras COE was pretty old too, maybe 4 years?  I think it was the 2011 variety but tasted perfect.  Loved that bean.  I find little gem's like that when my stash got shoved behind the Christmas guff in the cupboard and I didn't get to roast for a while because I didn't have the energy or willpower to tackle getting it out! lol.

All solved now.  But just got some Yirg from Chester via C-Man to try.  Should be fun.

Post by: Brett H on 04/03/2015, 09:28 PM
Excellent!  I remember the MyCuppa Harrar which was a generous freebie.  I'm not a huge fan of Harrar but that one was stunning!  Seems to be standard with MyCuppa offerings.

Title: Re: What Coffee are you roasting this week
Post by: Lacehim on 23/03/2015, 10:11 PM
I went crazy yesterday! :)

Went to roast and got fed up rummaging around in a box full of half empty bags.

Here's the blending results, a end of bag blend.  8)

Blend 1:
Ethiopia Yirgacheffe Gr2 wash 260g
PNG Wahgi AA 255gm

Roasted that one, 1C in 10mins with a preheated KKTO!  Man this new TO is fast!  slowed it down and pulled on 2C so a bit darker than I wanted.  Not what I intended but that's what you get when you juggled monitoring kids and roasting.

Blend 2:
Indo Sumatran Mandheling Kuda Mas 285gm
Costa Rica Herbeza Estate 320gm

Roasted this one second 1C in 10 mins (the old TO would have been getting there at 18!), and got all cosmic couple on this one, reduced the heat and coasted it for 3-4 mins and pulled before 2C.  It looked pretty good.

Yet to roast are

Blend 3:
Brazil Daterra Estate Opus 1 Exotic 125gm
Java Kalistat 2010 25gm
Panama Hacienda La Esmeralda 170gm

Blend 4:
Finca El Injerto Capadocia Caracol 155gm
Ethiopia Cuji Sidamo 135gm
PNG Wahgi AA 285gm

So, some bloody old beans there from when I started roasting but kept in a very cool, dark area (where Harry Potter lives) and hopefully will be fine.  Worse case they taste like rubbish, but even Jeff's old freebie is still ok.  Still got a 1kg or so of that left! :)  Who knows if I got any decent blends out of all that lot.  I just threw together what looked nice in my head!  A total experiment!  :rofl: :laugh:
Title: Re: What Coffee are you roasting this week
Post by: cosmic_couple22 on 24/03/2015, 01:10 AM
Good job Lacehim, keep away from that SC  :D  :stir,  all of them sound fine but if they are three years old or more there maybe some hard baggy notes from where the fats have absorbed things from the atmosphere and the lipids and bean structure have started to break down. 

You may get away with the Sumatran roast with the more earthy notes masking it but I think the fruitier coffees may not be as forgiving. At worst you have practiced your roasting technique on the new turbo oven, spring cleaned clearing out the old beans and had some time for yourself. Win win  :thumb:.
In the end as always see what happens in the cup.

Title: Re: What Coffee are you roasting this week
Post by: Lacehim on 24/03/2015, 09:04 AM
Yeah that's what I though Chester.  If it doesn't work out no loss I'll use after cleaning my machine and move on to the next bag.  Or Palm it off to the neighbour who drinks supermarket preground. Haha.  He's always happy with free coffee.

I'm trying to roast a little lighter for a change but as you know when your roasting if your not 100% concentrating things can go very wrong very quickly.

I am loving roasting again but I think I might have to grab another bag of your yirg that you did for Craig if you have any.  It was really nice.

Interesting though, as I thought a cold filter would have to be a lighter roast than the norm for espresso.

Currently roasting some Yirg Konga Sedie, and Sidamo Sasaba.   The Konga is a balanced mix of sweet cherry with a little citrus, and an unbelievably creamy mouthfeel. 

The Sasaba is cane sugar & date sweetness, with a looong fruity ripe melon aftertaste and plenty of acidity.  This one was Q graded at 90 and I can see why... :)

One thing I've been noticing is how the acidity is so much more pronounced when brewed on the old lever vs current hi-tech (and very expensive) machines.  Not sure if it's solely related to differences in the temps or due to the actual machines themselves.

2.5kg each of colombian pilatilo, indian tiger mountain, png sigri peaberry and tanzanian aaa on the KKTO and coretto.
Been extending drying phase to 7.00 minutes and has made a difference to the sweetness and body.

Post by: LeroyC on 29/10/2015, 04:40 AM
As I'm still very new to this game I grabbed a kg each of a couple of basic standards. A Colombian and a Kenyan. The Colombian is a Supremo and the Kenyan is an AB I think. I roasted 120g each in my popper for blending with each other. I've also tried them on their own. The Colombian is good both on its own and in the blend, but there's not enough oomph to cut through milk so I'll need something else to blend in for milk coffees. The Kenyan is no good on its own, but adds a nice touch to the blend.

Title: Re: What Coffee are you roasting this week
Post by: LeroyC on 09/11/2015, 08:47 PM
So just for the hell of it I thought I'd go the other way and increase the batch size. I'd read that Breville poppers could handle up to 170g of certain beans as long as you use a can chimney. So I weighed out 165g of Colombian Supremo and added them until the almost stopped moving in the popper. I then stirred them for the first couple of minutes. I heard a couple of pops at about 2.5min, but FC didn't start for real until just after 3min and it went for a good 60-80sec. I then roasted well into SC and dumped the beans at about 6min10sec.
After cooling the beans and tidying up a bit I followed the same procedure with some Kenyan AB and had similar results, but got to about 6min45sec before dumping the beans. Both batches look ok so I'll be interested to see how they taste. Both batches ended up being about 150g to start and 125g after roasting which equates to about a 16.5% loss. So I'm hopeful they'll be ok. The last lot of Colombian I did is too light for espresso, but isn't too bad through the Aeropress so I'll be able to use them fortunately. Anyway, here's tonight's results -

Yep, they tasted great. They took about 5 or 6 days to really come good and were best with milk, but the Colombian wasn't bad as a short black. The Kenyan was ok on its own but was better blended with the Colombian. I tried a few ratios and ran out before I really nailed a blend, but something like 2:1 Colombian:Kenyan seemed to work well.

I roasted some more last night and I think I'm really getting the hang of it. 129g of Colombian gave me 108g post roast and 125g of Kenyan gave me 102g roasted. Roast times were virtually identical to last time.

What times til first crack?

For larger roasts like 1kg to 1.2 kg
I preheat for a min 2 cycles of the TO @ 250 deg
Add beans
Roast at 250 deg all the way to finish
On this roast -  first crack was 14 minutes - And cusp of second crack was @ 18.5 min and then cooled

Photo tells the roast was roasted even and looking good

I,ll try mine without the heat guard next time.
Currently first crack is 20 min for 1 kg and 25-26 min til start second C.

If the beans are harder the times can be longer to first crack

Some high grown and dry grown African beans will take longer to first crack and some also rush to second crack quicker due to stored heat energy

It's been a while since I roasted because I have been moving and I finally dusted the KKTO off last week.  I roasted 600gm Columbia and 600gm Tiger Mountain and they both turned out great. :)  No fires or anything.  I had no cooler because I dismantled my old tolley with built in fan, so grabbed a cardboard box and made one out of that.  Worked like a charm, and it brought back old Memories!  That was how KK and I made my first cooler years ago!  :laugh:

Both roasts were roasted to just on the first few snaps of second crack, which is a bit darker than all these hipster roasts I've been buying.  It's amazing how much easier it is to control on the machine during pours when the roast is home roasted.  The grind doesn't need to be as fine, the is less blonding, and the pours just look better on the nakid etc.  Maybe it's just me, but I really notice the difference.

I'm sure the $180 of green that I just ordered from Brendan will help me get into the swing of things anyway! :)

Good stuff Lace!!  I roasted 1kg natural processed Brazilian.  I'm not a huge fan of Brazilians as a single origin but these are supurb.  They were sourced from DiBella of all places who had some interesting greens on hand.

I find different places have different types of beans so worth having a nosey about.  You never know what you might find.

Would be nice if we had local places here that sell green.  BG's prices have increased by the look of my last order.  Most beans were in the $17+/kg range, and no more bargain basement beans for blending :(  Remember when it was free freight over $50... those days are gone!  :coffee:

Yes!  The price of coffee as a commodity has risen hugely.  I have been buying and trying beans from a range of suppliers because if you're going to spend up you may as well get to know what's out there.  Mostly I've been really impressed especially with Ashton's Aussie Beans.  Price and taste they are just wonderful!

Great to hear BC!  I've always been reticent in recommending beans as I was burned early on on another forum when I couldn't wax lyrical about beans that folks were raving about but I thought were pretty ordinary!  Actually, compared to most other offerings..... No, nothing..... Go about your business.....

Beangreen prices are certainly more expensive but I have never once had beans from them that I felt were ordinary!!

My favourite blend at the moment is a mix of

60 per cent Peru Ceju de Salva, and
40 per cent Burindi Musema

Roasted to first signs of second crack

Its delicious with honeysuckle floral, and peanut brittle flavours - great as an espresso or with milk

still getting used to the humidity in Queensland when it comes to my roasts, find that I have to either give the roaster a preheat or factor in a longer (than usual) initial roast time for the first roast, seems to work fine after that

I also find myself roasting often at night when its cooler, and when there's no distractions or disturbances!

Greetings from the Sunny Coast!

I put 5 or so batches through the Behmor in the first week of March and have been away a couple of times since then and am only just getting back to it now. I just ran out of home roasted stuff this morning so I calculated quite well.
I roasted a 300g batch of Timor FTO last night as it's easy to roast and is fairly versatile. I've still got some Colombian Excelso greens which I'll use up this week, but I bought some Brazil Paracatu last week that I roasted today. I've never roasted a Brazil before and was wary that it'd require a different approach. So I started on P3 auto and stuck with it even though it seemed to be heating up very slowly. The exhaust fan does knock the chamber temp back a bit when it kicks in so I went to P4 manual at that point to make sure it didn't stall, then just nervously watched and waited while the temp seemed to crawl upwards, desperately resisting the urge to crank it.
Anyway, I think it seemed to go ok. 1C wasn't particularly loud, but that's not unusual for a Brazilian I believe. I heard a couple of snaps of 2C before I hit cool. Here's photos in natural and artificial light.

Well I've been quite busy roasting on the Behmor lately. Since the 23rd of May I've roasted the following:

• 250g Brazil Ipanema Estates 'Espresso'
• 250g Mexico Oaxaca (light filter roast by accident)
• 200g Mexico Oaxaca (espresso roast)
• 250g Brazil Ipanema
• 250g Peru Norte
• A pre-roast blend of 95g Peru Norte, 55g Congo SOPACDI, 50g Timor
• 250g Burundi AA
• 320g Timor

It's all gone quite well (except for the first Mexican) and I feel like I'm really getting a handle on it. The Brazil Ipanema and the second Mexican batch have been beautiful coffees to drink.

Here's a couple of pics:

Well done.

Better be careful admitting to preblend roasting however, as you lay yourself wide open to criticism from people that dont know much, despite the only relevant questions are "did it cup well / taste good?, "were you happy with the roast?" and "did you achieve what you wanted?"   ;D

Haha! Too true FC. To be honest I won't pre-blend very often myself as I don't think it makes sense on a Behmor. But I'm certainly not against it altogether as its another way to experiment with profiles and associated flavours.

I bet it does! LOL.

IMO the Behmor lacks the precise control of other roasters (including the KKTO and Corretto, not to mention pro level roasters) to be able to get really involved in the process. That and I lack the experience to make up for it. Plus I'm still only monitoring and recording everything manually, so until I get a better and more automated monitoring system I'll be keeping things relatively simple.

Finished drinking the blend and decided to do a roast for me so into the KKTO went 650grams of Skybury peaberry pulled at 230deg at 17min and am now enjoying beautiful triples.There is still some pre blending to be done with several part bags.

Was only 245g left, Behmor setting 1lb P2A, FC at 9:20, rolling at 9:45, end of FC 11:15, pulled at 12:45, moisture loss of 15.71%.

Fair few beans looked a little mottled after the roast.. but will see how they turned up!

hey Simon

I've got 5kg of similar green beans - Kenya AAA bold - I've been pushing them a bit harder in my roast profile on the behmor

i tend to ramp to first crack then temperature drop at end of FC and coast for 2 mins before applying heat once again and pulling the roast at the first snips of second crack

i don't seem to get enough colour on the beans for my liking otherwise and im loving them as SO espresso and in my cold brew coffee at the moment - sold a truck load of cold brew at the markets last weekend - so can't be doing too badly !

best

Ah awesome, thanks Pat! Yeah a stunning bean hey...

I've only got the old school auto Behmor without manual controls so can't alter those parameters. I still really don't understand all the different manual controls anyway (as in the reason why to ramp up fast, coast a bit then drop heat/apply more heat etc etc), don't understand the reasoning behind all the approaches hence my hesitation in getting the manual control panel to install, but that's great it gets a good brew out of it for ya!

Can't wait to try this one again, has been awhile...

Haha nice! It's weird, I keep seeing it written around that beans like Kenyans can be taken much darker than others, but surely that would mute alot of the amazing acidity and fruity characteristics of the bean?

From a long time admirer of this forum and highly infrequent poster ... my efforts yesterday - 280 g each of Peru Ceja de Selva and Ethiopia Limmu on the Behmor. Both taken just to start of 2C. Roasted the Peru last week and while nice as a latte, thought it would be better with some Ethiopian added. Will mix the two and see how it goes.

This morning:
Some more Costa Rica Tirra Estate Red Honey Process Caturra. This bean is so easy to roast, and responds well to different profiles. A family favourite as a SO espresso, or in a blend.
Panama Maunier Estate Natural process.
Burundi CAFEX. I only have a tiny amount left and have been saving it. Exceptional coffee.

Today’s roast is a is a larger KKTO batch

A unique blend of mostly expensive beans


450 Grams of Kenya Karimi Kirinyaga AB
300 Grams of Tanzania South AA
300 Grams of Sumatra Wahana
150 Grams of El Salvador Cosecha Fine AA

Total weight 1200 Grams or 1.2 KG
I want a chocolate bomb blend and hope this will deliver


The way I roast these larger batches is
Preroast to equalise all beans for about 5 min at 125 to 150 deg C
And start the roast proper at zero time when the preroast is complete

Yum... you'll have to let us know how it goes, sounds awesome. I haven't delved into blending yet, but it would be fun experimenting like that.


Felt like some good oooool India Elephant Hills AA! 300g in (3 separate batches), Behmor setting 1lb P2A

FC and rolling FC
-11/11:25
-11:15/11:40
-12:30/13

(Am assuming a lengthening because of the ambient temperature dropping, was later in the afternoon..)

End of FC:
-12:50
-13
-14:20

End of roast:
-15:20
-15:30
-16:50
(Stopped about 2:30 after end FC, or 1m before predicted start of SC)

Moisture loss:
-16.33%
-16%
-15.5%

Funny that the shorter roasts had the most moisture loss and viceversa hey! Wonder if I know in advance that the ambient temp is gonna drop whether it's worth taking the latter roasts a little further before dropping.. (usually previously they get faster roast after roast even after a fair cooling period)

I've mixed them all together in a big batch anyways ;D(https://uploads.tapatalk-cdn.com/20170928/4f12536974bb0319c33bb98e4e70a1df.jpg)

Currently roasting up some PNG Mt Ambra A (washed), it's been a long time, didn't realise I had so much of the greens left! Changed how I end my roasts and how I record them, instead predicting some 'projected' SC (which may or may not have been accurate), I'm just ending roasts based on time after end of FC. I never take roasts to SC anyway, so thought this would be far more consistent (it's not a massive change, but for consistency sake it really should be! Will see how it goes anyway)

I'm also changing how I approach subsequent roasts when done in a row. If the second/third roast is a bit longer before FC etc occurs (eg FC or end of FC occurs 15s later than prior roast), I'll extend the roast 15s later than the usual planned end time (so instead of exactly ending the roast 1m after end of FC, end at usual PLUS add the difference, ie end at 1m15s). Just to try avoiding some inconsistencies I've had with back to back roast moisture levels (and btw, not based on anything, just giving it a first crack XDXDXD). Dunno if that was coherent haha.

Did 3x300g roasts in the Behmor (1lbP3C), ended all roughly 1 minute after the end of FC, moisture losses: 15.16%, 15.16% (not a misprinted, STOKED with that haha) and 15.33%.(https://uploads.tapatalk-cdn.com/20171028/a5b75158ad9bb3dfb736e8000e42c57a.jpg)(https://uploads.tapatalk-cdn.com/20171028/7df780361a19ca215fa41319831ec1dc.jpg)

Last week I had an electrician at my house to fit out the whole of house smoke alarms 🚨
These alarms are - interlinked so if one is activated all will sound the alarm
They are hard wired in and have battery backup
It’s the law in QLD and although we have some time to comply -  I’m am early adopter for safety

Anyway I was roasting some coffee on the KKTO that was a blend heavy with African beans and the sparky and I got into a conversation about coffee ( as you do )

Helped him out with machine selection and roasted him a kilo of beans to take home

A win win for coffee

Post by: Simon on 09/11/2017, 02:01 PM
The Yirgs came out okay, did three batches, the first two 350g1lbP2A, the third at 350g1lbP3C.

With the first two my aim was to pull the first one about a minute and a half after the end of FC, and the second batch a minute after it to see which I preferred. The only thing is the second batch everything happened a bit sooner (30s roughly):

1st batch FC/Rolling FC: 13/13:15
2nd batch FC/Rolling FC: 12:30/12:45

1st batch end of FC: 14:40
2nd batch end of FC: 14:10

Was wondering if anyone had any advice with something, obviously this time I was wanting to pull the roasts at different times, but if I was wanting to get consistent roasts and get that second roast to the exact same depth (and moisture loss) as the first, what could I do? Even if I pulled both roasts a minute after the end of FC, they wouldn't be the same would they, because the roasts happened at different speeds... ?

I don't have any temp probe, but if that's probably the best way to measure it I may have to consider that hehe

Thanks in advance :)

Oh Simon.
I'm afraid your desire for relentless precision in everything you do (or at least, an explanation thereof) is juxtapose with the crudeness of your instruments (the roaster).

Much like the picture of the Cafe Aurora branded cup.

Don't worry Simon, 98% of commercial roasters are unable to achieve accurate back-to-back batches !

Thanks for the reply Jeff, and yeah fair enough. I know it's not possible to get the exact same replica of back to back results, it's not realistic for sure. Although strangely in a recent roast I got exactly the same moisture/weight loss levels in two back to back roasts which was freaky haha, but obviously there are too many variables like ambient temp and slight bean variation within the same green batch..

Am just trying to learn as much as I can and improve results where I can.. I'm sure it will just take more experimenting on my part to know what suits my roaster etc, and I think it's fair to want to improve and learn about getting consistent roasts, and whether anyone had pointers as to what the best approach was if the second batch of the same bean happens to be quicker/slower, but totally understand your point mate and have taken it on board, cheers.

Ps. haha yes very juxtaposed that cup compared with what's in it XD

The fact that the weight loss percentage on two particular roasts doesn’t actually mean that the roasts were the same as it’s only one variable. If you achieved it in exactly the same time at exactly the same temperatures along the whole length of the roast and the result was also the same roast depth when measured against a standard like Agtron then you could possibly say they were a match. Weight loss alone isn’t enough.

Thanks Leroy, yeah that's true, in this case even the timing of when everything happened (FC, end of FC) was spot on the same but am sure there might be other variables that may differ. The only thing is I have limited ways I can measure roast consistency, so tend to use moisture loss as a semidecent one, and am thinking of what I can do to alter subsequent roasts when the timing occurs differently..

Am gonna experiment and if the second roast occurs faster it obviously means things in the bean are happening faster, so I'll pull it a bit shorter compared to the first roast and see how we go. Obviously it can't be replicated down to a T, but it's something

Yeah pretty rarely they go off, but every now and then they will (if I forgot to open up the house a bit). The smoke alarm is in the hallway a bit further away, so all I do is open up the sliding door (and sometimes windows) while roasting and majority of smoke goes out there. It's really the only spot I can roast but it suits well :)

Some Yirgacheffe and some Burundi.

The Yirgys almost ended in disaster. I forgot to drop the temp. at first crack. I realised when things got a bit smokier than normal.
I quickly hit cool and opened the door on the Behmor to get them cooling quickly.
I was worried they would be charred but they look fine to me, a little "glossier" than usual but fine.
