Thanks, everyone, for the wonderful responses to my question. I learned
a whole lot.
At this point, I have roasted about 30 times with my iRoast-2. I started
with the eight half pound samples that came with it from SM and have
since purchased enough coffee so my husband is beginning to think that
we could open a shop.
My first coffee buying decision was to buy a whole lot of one kind of
bean that sounded interesting, and then to play with my new machine, and
my fairly elementary knowledge, and see what would come from it.
The bean I chose was the Horse Lot 19. I ordered 10 pounds of it and I
am going through it in a sorta methodical way, using one profile that I
felt was long enough so that I could try various things with it. So far,
This morning, I am drinking some very good Horse, roasted to what I
would call Full City/Full City Plus, and rested for 4 days. I am trying
different roasts all along the time line, from 1 day of rest through
seven. I'm looking forward to seeing what Day 5 will bring.
For this, urmmm, cycle, I stopped the roast with 45 seconds left of the
11 minute profile. Because Horse roasts unevenly, I ended up with about
5% of the beans that looked dark enough that I expected them to have oil
on them, but they didn't, 90% nice evenly roasted darkish, but not dark,
beans, and about 5% noticeably lighter ones. In my 130 gram batch, I
tossed out about a half dozen beans that never really roasted much at
all. This is noticeably different from what I saw during the last
"cycle" when I stopped the roast 30 seconds earlier.
I know that as people answered my post, there was a fair amount of
criticism of the machine itself--related to the 350 degree
pre-programmed start. I bought this machine because it was affordable
and the venting system made it practical for indoor roasting. Roasting
outdoors just can't happen here about six months a year.
I've had 30+ years of buying appliances that aren't exactly top of the
line, and learning to work around their limitations. This roaster seems
to be much the same. I know that I am seeing a definite relationship
between changes of the variables that are under my control and the end
results. For now, that is enough for me to feel good about the machine.
If we win the lottery, I'll get one of those neato sample roasters and
have an appropriate exhaust system installed in the house. But until
that happens, I'm betting that by learning as I go, I can nudge some
very fine coffee out of the iRoast-2 and my KMB pot.
Did I mention that I am loving' the cup I am drinking now?
