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!
How many lychee cofermented coffees can we have through our doors in 2025? I, for one, would like the number to be in the more-than-two range. 2024 is now a hallmark year for having more than one, but after tasting what they have to offer, I’d be happy to see them more often...
I had a very small sample of this coffee to work with, so I ended up starting very gently with a charge temperature of 455F, P8 power, and F2 fan. I rapidly increased fan speed to F3 at turning point, then reduced heat application to P7 a few seconds later. Due to the smaller batch size, I still hit a peak rate of change of 42F/min, but achieved a nice drop afterwards by adjusting the fan speed to F4. Anticipating a spike in rate of change at 355F, I dropped heat application to P6 and stayed the course until just before first crack. I then increased fan to F5, dropped heat to P5, and got even more air moving at F6 before dropping the (very fragrant) coffee into the cooling tray.
This coffee did want to take off at the end, but the result in the cup didn’t show any roasty or scorched notes, as I dropped at 9:08 / 397F, before they had the opportunity to develop. Lychee, of course, was the predominant note here. Plenty of wild bay leaf fragrance and caramel sweetness came through, but I’d be dishonest to call this coffee a subtle one. This is a super playful and intriguing cup that kept me coming back for more, always finding different notes. Watch the finish of your roast, and brew with confidence!
