Topic: Longest Time Between 1st and 2nd Crack (5 msgs / 139 lines)
1) From: Jeremy DeFranco
Mike,
     You mentioned that Stumptown uses a 5 minute lapse between 1st and 2nd
for Hairbender blend. Is this from beginning of 1st to beginning of 2nd OR
end of 1st to beginning of 2nd? Thanks for your help. So far Hairbender
style has worked well on GC, but I used a 5 minute lag between END of 1st
till beginning of 2nd. I'm wandering if, instead, I make it a 5 minute delay
from BEGINNING of 1st till beginning of 2nd might make for a bit more
complex cup. Cheers!
---I don't recall the time start of 1st of end of roast but early in my
profile
roasting days I did two roasts to test FrankenFormer Caffe' Rosto profile
capability extremes. A 5 minute French and on the opposite end of the
spectrum a 25 minute Cinnamon roast! IIRC that Cinnamon roast (of Panama
Songbird) was something like 12 to 15 minute start of 1st to end of roast.
To long a roast will indeed kill brightness regardless how light the final
roast level:-) Later profile experimenting found not only 1st through end of
roast affecting brightness but too slow a ramp tanning to start of 1st also
can/will flatten the taste.
The beauty of home roasting with total profile control you can experiment
with the same bean different lengths of roast and different profiles for
various lengths of roasts and compare results finding what you like best.
Now seldom will my roasts be shorter than 10:30 minutes nor longer than 16
minutes, seldom will tanning to start of 1st stage be slower than 20f/min
nor faster than 30f/min ramp, seldom will start of 1st to end of roast be
shorter than 3 minutes or longer than 6 minutes, seldom will pre-tanning
warm-up equalization stage be shorter than 3min or longer than 4min.

Don't recall saying that but it's been some time since I've been over and
watched Stumptown roast. I do know for years my timings have always been
stated from start of 1st. I also don't state timings 1st to 2nd as a rule
but rather start of 1st to end of roast. As I stated earlier post this
thread my profiles seldom faster than 3:30 nor longer than 6 minutes start
of 1st to end of roast, regardless the degree of roast. Best thing you can
do is experiment with various profiles and compare them yourself. I'm no
expert just do what I've worked out to be working well for me.

OK, Mike, I found the original post. Now I understand... Next time I
will try 5 1/2- 6 minutes from beginning of 1st to end of roast, and I
will stall it at finish temp as well. Looks like from what you said, a
slower ramp to than normal to first may enhance espresso roasts as
well?
Thanks, Jeremy
---Also very very important roasting for espresso shots is adequate profile
time. This is where stock air roasters fall short. I'd roast it pre-blended
to touch of 2nd in a leisurely 15min Rosto profile, 5&1/2 to 6min start of
1st to end of roast. Also "stall" the roast at finish temp for 20 to 30
seconds. So actually not touch of 2nd but more 20 to 30 seconds into 2nd
WITHOUT roast temp increasing from that point. (FWIW same/similar type of
finish Stumptown uses on their Hairbender.)

I do indeed use a "slightly" slower ramp tanning to start of 1st for
espresso blend target for shots. (Also to tame wild Kenyas) But only
slightly slower. My "norm" or base profile or stock profile is 25f/min
straight ramp start of tanning to start of 1st, espresso roast 20f/min. This
straight ramp "curve" is not the norm for an air roaster but rather more the
norm for a drum which I force upon air roasters primarily via direct heater
control:-) 
Gott run.

Thanks for your help, Mike. Off to the roast lab!
