Topic: Behmor and dark roasts (3 msgs / 67 lines)
1) From: Vicki Smith
In a recent weblog comment, this is what Tom said:
"true - it has limitations in doing extremely dark roasts, but as far as 
i define it, it definitely DOES espresso roasts. In fact, I can go 
darker with the behmor than we chose to go on the probat roaster (our 
commercial machine) when we do our roasted blends, ie Liquid Amber, 
Monkey Blend, etc … So unless you want a heavy, rolling 2nd crack French 
roast, the behmor is fine. The greater issue is that you have to stop 
the roast before your target “degree of roast” because (like all drum 
roasters) it has momentum and continues to roast a bit into the cooling 
cycle. So it takes some experience to do this …"
I'm sure we'll know more then we get to read Tom's observations once he 
posts his own guide to the machine.

The coffee beans go exothermic towards the end of a Vienna+ to French 
roast.  This makes control very difficult in an automatic device, not 
impossible, just difficult.  Does not the manual tell you that 1/2 pound 
batches will go to French OK?

It is a matter of not getting it too dark or out of control.  When I 
first tested one, I was not comfortable going very dark, i.e. 30 
seconds into 2nd.  For all of the profiles, the heaters are on 100% 
at the end, so coasting is not really possible.  You are plowing on 
at high speed.  Now with many more roasts under my belt, I could well 
take a roast that dark without much fear of losing it.  But I would 
be sitting there with my figure on the cool button just waiting for 
the right moment.
Also, you aren't going to be able to take 1 lb of bean to french on 
all of the profiles.  P1 and P2 for a lb would be my 
suggestion.  Finally, the Behmor 1600 has a smoke suppression 
system.  From the man himself (Joe) it was not designed and is not 
capable of good smoke suppression at a full heavy rolling 2nd.  You 
DO get smoke at that level.
And with all roasters, but IMO most especially this new 1 lb 
capability roaster (there is a lot of energy in 1 lb of coffee), 
don't you dare even think about walking away from the roaster and 
letting it shut the roast down itself.
