I've officially been roasting coffee for over a year - my first roast was on December 22, 2020, so my last roast prior to this one was before the year mark, although then I went so long without roasting that this one came at 13 months on the day. No matter. It's been a fun experience so far and I look forward to continuing it for many years to come! This was the last new roast out of my Burman order from October, and it's an origin that looms large in the history of coffee - according to legend, at least, the first person to bring coffee out of Yemen was a Sufi Muslim pilgrim from India who snuck a handful of beans back to his homeland. And indeed, said pilgrim was from Karnataka state on the southwest coast of India, from where these beans come. I think I've only had Indian coffee once before and I didn't love it, but that was also from The Roasterie, a popular Kansas City roaster whose output I never really warmed up to for whatever reason. So let's see how it goes when produced by my favorite roaster: me!
This wasn't an island coffee, but at a medium elevation I was expecting it maybe not to be a super dense bean, so I started the roast on P4 instead of P5, 75% power to the heating element. I also gave myself 20:00 to work with. Manual control, of course.
Chamber Temperature
19:00 - 77
18:00 - 107
17:00 - 140
16:00 - 168
15:00 - 192
14:00 - 212
13:00 - 230
12:00 - 219
Pretty much what you would have expected, I think - the 13:00 temperature, the last before the exhaust vent opened, was 54 degrees hotter than the Puerto Rico roast that I started on P3, but 57 degrees less than my most recent roast that I started on P5. Right in the middle. For these lower-temperature roasts I haven't been waiting until the beans start to yellow to alter the heat profile; when the vent opened at 12:30, I increased the drum speed. They were getting into the yellowing phase about a minute later.
Exhaust Temperature
12:00 - 177
11:00 - 255
10:00 - 293
9:00 - 314
8:00 - 327
7:00 - 338
6:00 - 345
5:00 - 354
4:00 - 363
3:00 - 372
2:00 - 379
At 7:00 left, with the beans just starting to turn brown, I upped the heat to P5 for four minutes, then dropped it back to P4 at 3:00 with the A temp having gone over 370 and first crack just starting. This was a lengthier first crack than I frequently get, about 75 seconds. I had originally intended to wait 2 full minutes from the start of first crack before sending the beans to cool, because I wanted to roast this batch to the full side of medium, but with 1:15 left the A temp was over 380 and the beans were smelling pretty done - I certainly didn't want to get near second crack, and 45 seconds can be a lot of time at this point in the roast. So I sent the roaster into the cooling cycle at 1:15. The A temp peaked at 388, then dropped; I opened the door after 90 seconds as usual.
Complete Roast Time: 18:45
Post-Roast Weight: 196 grams
Loss Percentage: 14.8%
That's right about what I was shooting for - as I've noted often in the past, you can't always tell just based on the number, but it should come out as a full medium.
