Hello Everyone
I’d like to ask you about recipes. For example, if Rob Hoos’ recipe is for 150g, if I want to roast 300, 500, or 1kg of coffee beans, what variables should I adjust?
Depends what you’re trying to achieve but I would start with a higher charge temp and power.
I roast 200g often but have been experimenting with 350g and 500g recently. I noticed I have to implement fan towards the end of the roast for +350g batches.
The best way to figure out is through trial, I think. Start by matching end color of the beans, development percentage, and lastly first crack timing. Make a roast profile plan, execute, evaluate, and make single adjustments to variables.
Check the screenshot attached. It’s from the Aillio BulletR1V2 official manual:
Hope that helps.
