Having brewed with gas in the Arizona desert presented unique challenges. Sweat and slippery hands aside, one of the most challenging aspects was temperature control. You could get an initial mash temp set fine but after adding the grains the temp starts to go so you turn up the heat and keep chasing it during the entire process. Boil overs were messy and you had to stay with the rig as long as it was flame on. Needless to say, I skewed a few batches due to temps fluxing. The reason I chose gas over electric was cost. We already had energy bills shooting north of $700usd mth (AC and pool pumps).
I'll soon have the chance to build a new brew room and the next brew setup will "definitely" be electric. Looking at the Grainfather G40.
So those on the fence about deciding with gas or electric take note.
