Topic: HotTop emulation >was Re: + HotTop profiling (66 lines)
1) From: Mike McGinness
I've just finished 5 batches of my usual profile roasting, read and re-read
some list posts and okay John you talked me into it:
I chose to use Panama La Berlina as the subject bean.
My now 'usual' profile is 435f in 11min. slow fast slow:
(Ambient 76f roasting with my 'cooler' Caffe' Rosto)
170 @1min (92v)
230 @2min (91v)
350 @3:30 (127v to 350 then drop to 110v)
380 @5:30 continuing temp/voltage increase @ 10 per minute to 435 11 min
(actual was 11:10, peak roasting voltage after 350 113.5v)
After reviewing the HotTop data John (no longer wandering Texas?) provided I
targeted 355 @14 and 435 @17 actuals follow:
@1:00min 148 @90v
2:00 210  "
3:00 249  "
4:00 270  "
5:00 289  "
6:00 298  " rise seemed too fast, lowered to 88.5v at this point
7:00 302  @88.5v oops, now too slow, upped to 89v
8:00 303 @89v upped to 90.5v
9:00 311 @90.5v upped to 91v
10:00 315 @91v upped to 92v
11:00 319 @92v upped to 93.5v
12:00 325 @93.5v upped to 95v
13:00 340 @95v upped to 99v
14:00 349 @99v upped to 110v
15:00 375 @110v upped to 113v
16:00 400 @113v upped to 117v
17:00 415 @117v upped to 124v
435f @17:47
Not as smooth a temp/voltage increase as hoped for but of course a new
profile would take some dialing in. Times etc. seemed to come out about
right though... Will see how they taste compare in a day or so! My guess is
the long slow build roast will have less highlights but we'll see. I've been
very happy with my modified Black Bear 11min Full City 435f profile so
it'll be tough to beat anyway...
BTW, neither of these two roasts were designed to reach 2nd crack... and
didn't. (duh, up around 446f :-)
