Aillio Bullet R1 IBTS Analysis by Evan Gilman
Unless otherwise noted, we use both the roast.world site and Artisan software to document our roasts on the Bullet. You can find our roast documentation below, by searching on roast.world, or by clicking on the Artisan links below.
Generally, we have good results starting our 500g roasts with 428F preheating, P6 power, F2 fan, and d6 drum speed. Take a look at our roast profiles below, as they are constantly changing!
Nearly every year, we get a look at this atypical and phenomenal natural coffee from CoopeDota. Consistency is clearly their strong suit, and this mark has made it to the Crown Jewel menu every one of those years - it never disappoints.
This is also a super dense coffee that I knew would take on plenty of heat, and continue a trajectory past 330F without much prompting. I started with plenty of heat, dropping 500g of this coffee into a 428F barrel, with only F1 fan application. The goal was to get through Green/Drying phase expeditiously, and that definitely happened! At 264F / 2:00 the roast was moving so quickly that I reduced heat to P7 and increased fan to F2, then F3, then F4 going into yellowing at 4:00. “This coffee can really cook!” I thought to myself. So much so that I reduced heat to P6 and increased fan speed to F5 at 365F / 6:40, then P5 at first crack. The crack on this coffee is fairly soft, so keep an ear to the drum to make sure you catch the small pops. In the end, I was able to get a ratio of 39% / 46% / 14% - a healthy amount of time in Post-Crack Development with an end temperature of 403.7F at 10:27. A little on the higher end of the temperature range, but nothing too dark.
All was revealed as I cleaned the chaff canister on the Bullet – it was completely full! What’s more, the chaff screen was completely caked with chaff and oils. I would say that it’s a safe bet to clean your machine before and after roasting this coffee! My troubles with airflow were clearly due to the interaction of chaff on the screen, so your milage may vary using my roast curve above! A word of warning.
That being said, the coffee was still delicious, and a credit to its producers at CoopeDota once again. Dried apricot, and a finish like lemon zest. Guava and dark chocolate came through on this roast as well, but I think the flavors could have been even better with more airflow and a sparkling clean machine. Still, drinking this coffee is always a pleasure and allows me to reminisce on Crown Jewels past. Delectable!
