What is the most difficult roast to master?

What level of roast is the most difficult to master, because it has a tiny margin of error?

I think roasting really light is challenging due to trying to get to first crack with enough momentum, but then slamming on the brakes to get a proper development time. For example, if 1st crack starts around 385F and you have a desired drop temp of 394F, you really have to get that ROR down to achieve that end temp with 2-3 min of development time.

Roasting light is relatively easy. Roasting dark well is much tougher because chemistry is most reactive at heat and the roast moves much faster between 420F and 430F than it does between 390F and 410F. It takes real skill to preserve acidity and sweetness at darker roast levels.

The lighter you roast is easy....the 2nd crack roasts and beyond are more difficult just because time is everything....sometimes it’s just seconds before it burns.... or shall we say French Roast.

Roasting is an art. Yes, you are right that there is a little margin of error and if you go too far your bean will get on fire. So, please be very careful, since our rostering company had been few times in this situation. The most difficult is the dark roast coffee, which requires the perfect point between being dark roasted and or being burn. If you need some assistance, you may contact us.
