Hi all,
First post to the list here. In the spirit of this thread I just roasted 
a pound of Columbia Pedregal Agua Blanca microlot to just about C+. 
Dumped the beans 2:45 after the first first crack (bean temp was 415F). 
I always roast for espresso nowadays and this is the first time I 
dropped the beans with less than a 3:15 stretch so this may be a real 
eye opener. Lately I've been doing 3:30-4 minutes stretches and haven't 
gone to second crack in quite a while. Thanks for the inspiration.
