Hey bud, I'm from SoCal too and have been trying to beat the heat as well. I'm worried this heat will make my beer bitter.
I read somewhere that wrapping a damp towel around the fermenter will cool the fermenter. Lose heat through evaporation maybe? I just started it yesterday and am not sure if it's working, but thought it was worth a shot. I'd be interested in knowing what else you guys have been trying.
