What Coffee are you roasting this week

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

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?

Simon

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 🙂

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 KK

Ah nice KK sounds delish 🙂. Let us know how it turns out tastewise!

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.

Brett_H

Looks great!! I love those canisters too!!

Cuir_Beluga

Thanks Brett. I have only just started using them.

why not use fresh roasted coffee?
