Hi everyone, I’ve been doing some experimenting with my roast profiles lately to see what kind of effect they have on the final cup and roast trajectory in general and what I’ve been seeing has been surprising so I’d love to hear your thoughts!
My recipes are typically 775g with preheats between 275/280*C as a baseline. Previously I had beeb charging the roast at P8 then P9 then working my way down with some P + F adjustments but leaving D9 the whole roast.
I’ve now tried on about 6 different beans to charge the beans at P2 for about a minute before jumping to P9 and making adjustments from there to P + F. Drum remains D9 throughout. What’s been surprising to me is that the roasts with a soak carry more heat/momentum into FC than without a soak. Without a soak I rarely/if ever need to get to F4/5 and usually maintain P7 into/through development unless I need to drop to P6. With these roasts utilizing a soak period I actively need to hit F4/P6 around ~190* in order to avoid blowing through FC with RoR around 11/12*
I supposed my shock is that less power early on and that soak time would have stunted my roasts but instead it appears it has accelerated them to some degree. What are your experiences w/ or w/out soak?
