I have a teeeeeeny tiiiiiiiiny roasting businesss and typically, I roast on Sunday. However, I had a client who needed a roast done earlier than my specified cut off time. No biggie. So I’m trying to be cute and just replay the most recent roast that I had for the bean.
Whoops.
The most recent roast was for 450g. I just dropped 900g. Who has two thumbs and doesn’t notice anything unusual? This guy.
Despite being double the weight, There is basically zero difference in the overlay until the first temp drop. I was pretty shocked. Do I need a 300C preheat and p9 for a 900g batch? This (singular) data point says…maybe not,
I guess the point I’m making it you don’t need to live and die by the technique.
Just being curious, but setting aside the curves, did your milestones match? Going by personal experience, your FC should have happened a minute or two later with the bigger batch size than the smaller one. Going with a higher PH would give similar timing for the milestones like FC and SC, IMHO.
