I'm thinking that must smell as good as it looks.  It should be a treat in the V60!!

Haha it truly does smell incredible! Although it think the accidental flash added to its radiant looks! ;D

Still working it out in the V60, but yeah has been soooo long since I've done a filter roast.. so excited bout that!

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%.

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

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

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.
I love coffee. It's as simple as that.

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

I’ve come late to this thread but it certainly hasn’t disappointed.  So much good stuff here.  Simon, are you roasting in your kitchen?

Hehe certainly am, I store the Behmor in the cupboard usually though when it's not being used, coffee stuff is already taking up a fair bit of room hehe

How do your smoke alarms cope?  Do you have a decent Range Hood?

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 :)
