Topic: AlpenRost outdoor roast in Fall temps and re-roast experiement.. (34 lines)
1) From: coffenut
Well, I think I've discovered the outdoor temperature where my Alp doesn't
perform well with outdoor roasts.  Got up this morning, the outside temp was
54 deg and started a roast of Harar Horse.  At higher outdoor temps 65+, the
Harar usually hits 1st crack around 13 minutes on my "hot calibrated" Alp.
Today, at 15 minutes into the roast, I still had no distinctive 1st crack.
The whole roast was very weird from the standpoint of hearing cracks.
Anyway, I let the roast go 17 1/2 minutes and went to manual cool down;
which was about 2 minutes longer than I would normally roast Harar to
achieve a full city level.  The roast result was barely a city level and
noticeably under-roasted.  Munching on a bean told me there was still some
grassy taste left too.
So, I waited until the outdoor temp came up to 64 deg and tried another
batch of Harar.  This time, the beans behaved normally and the roast result
was a very nice full city level.  While the Alp was still pretty warm from
this roast, I tossed the previous under-roasted Harar beans back into the
drum and started a re-roast.  I figured, "what have I got to lose" and it's
a good time to see what happens with a re-roast experiment.  At 8-9 minutes
into the re-roast, I could see the roast was back underway and getting some
good smoke levels.  No 1st cracks were left in the beans, but I got a
distinct 2nd crack level at 10 minutes into the process.  I allowed 2nd to
continue for about 40 seconds and went to manual cool down.  The result was
a nice full city color and a dark, dry bean.  Munching on a bean told me
that I had gotten the roast to the level I usually like with Harar.  I'm
going to let the re-roast batch rest for 3 days and see if its anything
close to the usual wonderful Harar flavor.
Just thought I'd share this experience with the group.  Guess I need to get
cracking on building my indoor smoke-chamber for the Alp before it gets too
cold to roast outdoors.
