Behmor Plus Drum Speed Comparison

Behmor Plus Drum Speed Comparison

August 25, 2014

A faster drum in a Behmor means that the coffee gets pulled farther up the back of the drum during roation which exposes the bean mass to more heat from the the upper heat element in the back of the roaster. This actually shortens roast time which might be a good thing for folks dealing with roasters that aren't getting hot enough in the time the Behmor 1600 allows.

We roasted 2 half pound batches of Ethiopia Sidama Dereje Station to a city roast level using the slow and fast speeds. The slow drum batch went into the cooling cycle after 11 minutes and 15 seconds. The fast drum batch started cooling at 10 minutes and 45 seconds.  After 2 days, we compared the grind color.
