Topic: HGDB technique (4 msgs / 127 lines)
1) From: Julie Tieszen
Hi all,
I need some help from those of you who have "mastered" the HGDB method. I have been doing this for a few months and enjoy the coffee quite a bit more than when I used an unmodified popper. I usually roast about a cup and a half of greens at a time and it takes 7-8 minutes to get to 1st crack. However when I put more intense heat on it when 1st crack starts it seems to bring on 2nd crack too quickly. How do I get more space between them? How long should  I encourage 1st crack before pulling back the heat?
I've done some research on the archives but couldn't find anything to specifically help with this issue.
Thanks! 
Julie

To get more gap between 1st and 2nd, pull the nozzle back a bit from
the beans and let it catch "more air" with the hot jet from the
nozzle.  And STIR,STIR,STIR,STIR,STIR. I take the HG and rotate it
around the outside edges of the batch, too.  Every so often I'll bring
the nozzle back down and then back out again trying to coax out a
final outlying first crack. After a while the smoke will sharpen in
smell and get more voluminous.  2nd crack is very close at that point.

I have not mastered it yet, but overall I am getting better results than
when I started.  Still lots to learn.
You might try putting the "more intense heat" on after they have dried and
are turning brown.  When 1st starts to end, I lower the temperature of the
gun by opening the air shutter on the 751 look-alike gun.  I try to keep the
bean temperature climbing, but at a slower rate till finished.  I have used
a thermocouple to help find gun setting and positions, but a little trial
and error should work just as well.  I find the coffee is sweeter when the
time between 1st and 2nd is extended over several minutes.

Thanks Justin and John. That's the kind of help I need! And John, you =
answered the question I forgot to ask......how the coffee is different =
when there is a longer time between 1st and 2nd.
