First off, hi Jason, from another high altitude Lutheran (WELS) pastor/brewer
. I'm at about 7,000'. I have not made any adjustments for high altitude. And I appreciate your sig line.
I'm curious about IowaStateFan's assertion about hops utilization at high altitude. I'm absolutely no expert, so I have no basis to contest it. However, I asked a similar question a while back on a different homebrew board, and the answer given, which seems plausible to me, was that hops utilization is effected by the agitation of the boiling water, not the temperature. If that's true, then altitude and temp should not impact hops utilization at all.
Any thoughts on that?
