Hi everyone, new owner of an R1 v2 (new to me!) and am trying to learn the roaster. I’ve been watching some of Morten’s videos and was wondering if others had already adapted his 1kg R1 standard roast profile to 350g.
HIs 1kg being: 300C Preheat, Charge P9, D9, F3 → 150C P7 → 190C P5 for a 9 min ish first crack and an AG75 drop at 3 minutes of development.
Would 250C Preheat, Charge P7, D9, F3 → 150C P6 190C P4 get you in the ballpark? Need to order more greens but figured I’d post in case.
I’ve been experimenting with this exact same issue. Trying to use his general approach but on 350 g batches. I’ve settled generally on a much lower preheat (210 or 215), then I start at p6 f3 until I hit 150 degrees and then step down from there. Seems to put me generally in the right ballpark on first crack and the development time.
Did you try the Aillio recommended recipe from their owners manual? It’s set for 350g.
R2 Pro Roast Recipe Example: 350g
The following roast should finish in about 7-9 minutes or less.
Roast Level: Light
Weight: 350 grams
Preheat: 220°C
Charge Settings: Power 7, Fan 2, Drum 9
Infrared Bean Temp120°C Power 6, Fan 3
Infrared Bean Temp165° C Power 5
Infrared Bean Temp190° C Power 4
Infrared Bean Temp200° C Fan 4
<First Crack Begins196-204°C>
45-90 seconds after First Crack: End the Roast
Try that recommended recipe above. I would probably not touch the fan settings until post FC though. Depending on how your exhaust sytem is set up, it can crash RoR causing the roast to stall especially if the batches are small. Only use fan if you see smoke building up.
Let me know how it goes as I want to experiment with ~350g batches as well.
I roast under a large kitchen hood with a small alluminum tube attached to the bullet. I mostly roast 200g with the following for a dense Guatemala:
210 preheat, 30C ambient temp, 45% ish humidity
Charge P6, D9, F2 → 120C P5 → 180C P4 → 200C P3 → 214 P2 → 3min dev time
