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!

I roasted a mixed and improvised an Afro/PNG mix on the KKTO

600 grams of PNG Kinjibi
300 grams of  Ethiopian Gambala Naturals

Gave about 200grams to the surgeon to do a good operation on me

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

I wont point out who it is for privacy reasons but the KKTO owner has left a testimonial on the Koffee Kosmo Roaster site

took it to first snap of second crack in hindsight I'd like to take it a little darker but there was nothing wrong with the flavour!

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

Just roasted up some Sulawesi Toraja Utara 600g on the KKTO, last lot went pretty quick so can't wait till this settles.

Echo your comments on ease of use KK I love the reliability of the thing, congratulations.

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
