Topic: more on outdoor HWP roasting (5 msgs / 50 lines)
1) From: Prabhakar Ragde
Tried a second roast outside. It was cooler, overcast, with a higher
relative humidity -- I could see my breath. Set the machine on 5.5, my
usual setting, with 3 oz Espresso Monkey, held my watch in my hand,
and listened intently. First crack at around 5:30, machine shut off at
8:00 without going into second crack. I restarted and gave it three
more minutes before I heard second crack. Gave it a few more seconds
and then stopped it. 
Quite different behaviour from the last roast I did outside, which
went too fast. Now I'm really confused. --PR

Ambient temps make a big difference, PR.  I live in the same part of the
world as you, and the difference in roast times a ten degree change in temp
can produce can be rather dramatic.

Ya! Watch things go out of control the other way when you hit that 90 degree
heat outdoors.

Okay, but I don't understand how it can burn one roast and undercook
the next. --PR (manfully resisting puns on "Solaas" and "solace")

Ever hear of wind chill factor, PR?  
P.S. the Italian side of the family is Solis.  Don't resist!
