Topic: varac....Mike (2 msgs / 39 lines)
1) From: Ron Ehsani
I too have a Caffe' Rosto and the same variac as Mike.  I drink primarily 
espresso and leave the variac at 115 volts during the roast for an approx. 
13 - 14 min. roast at 70F.  My question is how do you suggest I vary the 
voltage (and when) during the roast to achieve a good profile for better 
roast and thicker body for espresso?
BTW, I'v been a full time lurker and part-time poster for some time now.  
I'm Ron Ehsani from Dallas.  I use a MM grinder and a Gioto.
Thanks Ron E.

"Better roast" is open to debate and individual taste. For a longer roast
yielding more body you can simply reduce your voltage. You didn't say how
dark you're roasting but if your roast was maxing out temp wise with 115v
you'll need to up the voltage as you approach 2nd crack (from the new
reduced voltage). The only way to find out what works best for you is to
play with it! I find slowing the roast from just before 1st crack to begin
of 2nd gives better body (targeting 6min or so for this ramp stage)
