Topic: HG profiling - rambling (sorry) (48 lines)
1) From: john nanavati
I made a realization last week when I roasted some decaf. I took a slower
ramp up because I heard that it's easy to burn or over roast; so, i took
more time before first crack with the roast than I normally do and found
that it made a really smooth (filtered) brew (Mexico Organic Oaxaca WP
Decaf).
I use a Milwaukee HG (570/1000) and roast half a pound at a time.
Normally, I would take about 15min to achieve FC+
6:00 at 570
9:00 at 1000
I'll reach first crack about 11:00
(btw, those ipoders out there. it has a really nice stopwatch with a lap
feature that i like)
I applied this to a bean that I'm currently drinking (Java Government Estate
Djampit) and started stretching out the ramp-up a little and
roasted 18min to FC+
9:00 at 570
9:00 at 1000
reaching first crack at 14:00
I know that if I stretch out the ramp up too much that I run the risk of
baking the beans. although, i don't think that i'm really close to that.
I started researching HG profiles in the archives and noticed John Moody's
observation last month that stretching out the time between first and second
crack sweetened his roasts. I'll have to give this a go during my next roast
- maybe i'll try 8:00 and 10:00 on my next roast.
I've always been afraid to back off the roast for fear of stalling any
suggestions about how to know that's happening or how to avoid it?
Also, how long can you run a roast without killing the result? I don't mean
burning it. But, let's say (worst case) that I back off my heatgun to 570
and stall the roast. I assume that it will continue to darken and may
produce some smoke around 20 min but never get into second crack.
So, other HG-ers. How do you run your roasting profile?
