Topic: Roasting Decafs in Behmor (was: Anyone attempting to Mod a Behmor for a bean mass reading?) (2 msgs / 214 lines)
1) From: Bonnie Polkinghorn
Hello David, Kevin, friends,
I got my Behmor for Christmas and already have about 28 roasts on it, mainl=
y
all decaf, because that is what I drink, please don't throw tomatoes at me.
I also roast regular coffee for friends and to learn about what you all are
always talking about.
I have had great success roasting decaf in the Behmor, easily getting C+ an=
d
FC roasts.  I have lately been roasting with 12 oz of beans, settings P2, 1
lb.
Lately, I have been using the P2 profile and playing with the times to
lengthen or shorten the time the roast is in the lower temp. at the end of
the profile.
I like the P2 setting because it lowers the roasting temp at the end of the
roast, in my mind easing into 1st crack, making it a longer time between 1s=
t
and 2nd, more important with the decaf.
It's explained in the manual, and I have just come to understand what it
means.
On P2, if you do nothing until the end of the roast, for example, it has 1
minute left and you have not yet heard first crack, and so you add time, yo=
u
are lengthening the end of the profile with the lower temp.
If you want to lengthen the time it's in the higher temp section of the
profile, add time before hitting start, then subtract time after it starts.
For example, there are 5 minutes left and you hear first crack, you would
need to subtract time until you see about 1 minute (for C+), or just listen
and hit cool when you want, you have, in effect, shortened the time at the
lower temp. of the profile.
If you do the opposite, say the program P2 comes up for 18 minutes, and you
subtract time before hitting start (lets say changing it to 15 minutes) and
you add time after it begins, you have in effect shortened the beginning
(high temp) and lengthened the end (lower temp) of the profile.
To summarize, for my decafs, I want to be sure that when I start to hear
first crack, I have only about 1 minute left in the program, I listen and
hit + to add 15 seconds, keep hitting + until that moment I want to hit
cool, which is normally about 30 seconds after first crack stops.
This is a moment on my learning curve, I may be way off, I'm still learning
and trying to understand, so take what I have to say with a grain of salt,
if I'm off base, let me know, I won't be offended, and TIA,
Bonnie in Santa Rosa
