Subject: +Tipping on beans
Last night i roasted a preroast blend of 2 parts
sumatra volkopo and 1 part harrar FTO.
Roasted in my drum roasted, using the usual profile.
But it seemed that these beans started smoking heavily
right around 1st crack (usually the heavy smoke
doesn't start till into 2nd crack).
Another odd thing, is that it looks like i've "tipped"
these beans. Some of the beans have darker spots on
the tips. I've read this means my ramp was too
fast..but it was no different than it always is. Any
my profile was (bean temps):
2 min 15sec mins to 165
1min 45 sec to 225
1min 15 sec to 265
3 min 15 sec to 330
3 min to 385
1st crack at 390
1min 40 to 410
1 min 20 to 430
30 sec to 435, 2nd crack
1 min to 447, eject.
I roasted some of the Volkopi two days ago and it was a very uneven roast
with lots of tipping. I think part of it is just he nature of this bean.
The Kona I roasted did not tip/
