This leads to slower maturation for the plant and a denser coffee bean as a result that’s forgiving in the roaster. These two factors make Burundi coffee a fantastic bean to turn to when starting your foray into roasting.

(about 7 min in), so it’s imperative that I fluctuate heat settings to avoid this. For me, this means dropping the heat setting to P3 (50%) when the chamber temperature reaches 315F.
From there, I basically toggle the heat input between P4 (75%) and P5 trying to stay above 300F but not hitting 325F! It can be a delicate dance, but you get pretty good at keeping roast progression steady with a little practice.
This roast hit 1st Crack at 8:40 seconds in, hitting the cool button 1:40 seconds after the the first audible snaps. I open the door while cooling to aid in stopping the roast process and cool the batch faster. Weight loss was 14%, a little darker than I’d hoped for but a solid City+.

This is a good starting point for this coffee, adjusting for +/- bittersweetness and chocolatey roast tones(of which this coffee can produce plenty!). For those who prefer to use the pre-program modes, try starting with the 1 LB setting for 1/2 LB of coffee or less, and P1 (full power). There should be a noticeable decline in snaps with this coffee marking the end of 1st crack, at which time you can cool the roast (roughly 1 – 1:20 after the beginning of 1st crack)
Roast #2 Full City
I planned to slow the roast down sooner for my darker roast by dialing back the heat when reaching a temp much closer to 300F, extending the latter leg of the Roast Profile refers to the relationship between time and temperature in coffee roasting, with the endpoint being the "degree of roast". Roast profiling is the active manipulation of.... Seemed like the Behmor knew my plan and did it for me! I’m not exactly sure why, but my 2nd pass was about 20F behind roast #1 most of the way through, even though I employed the same roast parameters out of the gate.
However, it’s worth noting that the rate of rise was faster. I did pre-heat the roaster before each batch for 40 seconds on P5 before loading the grid drum with coffee, so there’s a chance this inconsistency comes from lag time on loading the drum and starting the actual roast.
In the end, 1st crack occurred at 9:50 seconds into the roast and I let it coast for 3 full minutes before cooling. There were a couple of 2nd crack snaps in the drum at the beginning of the cooling phase, but opening the front door did a pretty good job of cutting the roast short.
