First roast Congo Kivu Kalehe Coop

[abunnell]

Got a sampler from Sweet Maria's and this was my first real roast. Any notes or tips would be amazing and very much appreciated. I have noticed that the majority of my roasts fall flat. I haven't had the over roasted experience but I may be dropping underdeveloped coffee?

First, welcome!
I have about the same comments on this roast as I had on the Brazil Alta Vista roast. I.e. I recommend that you charge at a lower temp, so that the Turning Point (TP) falls at or below 210F. Then you can give the roast more heat during the roast instead of just having to push the brakes all the time.
The time from 1Cs (First Crack start) to drop seems fine. As you were going for a light roast, it's hard to get very long time in that phase without stalling the roast.

Underdeveloped coffee is more astringent, and baked is another descriptor for flat.

It looks like you could shorten up the ramp to 1C after EOD (3-4 minutes); then RD (roast development) 1:30-2:00 after the onset of 1C.

Thank you both! I'm going to try this and see how it turns out. I've been trying out on a sampler from Sweet Maria's but will be getting 20 pounds of one coffee to really try and learn more about controlling it,.
