Roasted up a little Yirg Natural for filter the other night, gonna V60 it tomorrow, super excited

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

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%.

Looking good Simon 👌

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

Ah that's a cool story KK, coffee unites hehe

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

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

This afternoon I have just completed a 1kg roast blend

3 bean blend of equal parts

Ethiopia
Brazil
Guatemala

Should taste like fruit chocolate based on the taste description of the beans
