Hi everyone, I’m having issues to match light roast in both sides of the beans. When i measured the whole bean im getting 60 agtron level and ground bean 80 agtron level. I thinks There’s a big different so anyone can chare some tips how to avoid it?
Maybe I’m preheating to high? Maybe i need more airflow? Drum speed?
My batches sizes is 350gr 220c ph P0 (soaking for a minute)P6 f2 d9
I’m sharing my last roast.
I’m doing filter grind (23 clicks on the el comandante grinder). Last day I was reading rao and he was saying to grind fine for the test. I did las time and now I have 95 agtron level, so I have more difference than before
Hey-not being critical here.
I’ve found that I need a little more momentum in the roast to bring the interior and exterior colors closer together. So, what I would do would be to charge say 5C hotter or go to 7H, stay there 5-10C longer then make cuts. Goal is a little steeper slope. FWIW, I aim for a 7C-8C FC delta at 14%-16% for a light roast.
Also FWIW and FYI, just in case you weren’t aware, the bean mass probe reads a lot differently at really small batch sizes. You’re roasting about 1/3. I understand you’re probably working out samples for production but it’ll change as you scale up. Good luck.
