Hello,

I always get tipping on my Guatemala roasts. Even if I reduce the PH temperature a lot (I started with 220 deg C). Can someone help me to roast the Guatemala washed bean to a City plus roast with chocolate/ nut flavour?

Thanks a lot!

I use that preheat temp (220C or 240C) for 800 gram roasts. You’re doing 150g? Probably too hot. (edit: oh, I see you did 165C PH. that seems appropriate for a small batch)

150g can be hard to dial in on the bullet, because the bean probe not touching a lot of beans.

My first suggestion would be try a larger batch size (250? 300?)

Thanks a lot, do you guys have a roasting profile for a 300g or more batch size?

Starting at P9 for 150g batch will scold your beans no matter what pre heat setting you have. Try starting at a gentle power setting for that batch size
