I am really new to roasting world, and aillio bullet v2 is my first ever roast machine. I am currently learning to roast by reading books like the coffee roaster’s companion by Scott Rao and modulating the flavor profile of coffee by Rob Hoos.
For me both books are incredibly informative. But I find Rob’s book is more applicable as he explains clearly about the variables on the profile and how those affect the outcome. As he explained that playing with the length of MAI and Development will yield different results, I am more comfortable to plan the time lenght by targeting a constant RoR to reach FC from yellow point in MAI phase, or to reach end temperature from FC in development phase.
But as Scott rao mention in his book, that RoR needs to steadily declining from yellow point to the end of the roast. That makes me confuse on planning the profile. Do I have to calculate the declining RoR with derivative formula so I could get RoR targets on my time interval? Or I’m just too busy with math?
I found an article (I forgot which one) says that the declining RoR happened naturally only with bigger machine. What do you guys think about it? Does it really matter if I roast with aillio bullet v2?
As far as I try with straight RoR, I couldn’t detect any baked or flat flavor (I could find it on too long dev. phase though) . But I couldn’t just believe my tounge now as my cupping skill is not that good.
I’m more than pleased if you could share your experience and thoughts here…
