Wow, don't know where you guys have been! I've seen it discussed often through the years.
Yeah, believe it or not I wasn't just yankin' yer .... in the other thread.
The progression was MrBeer, PM, AG, throw a kegerator in there somewhere, and temp control kinda came last.
That said, I am in my unfinished fermenting chamber (basement) which is 58 now and tops out uppper 60's in the dead of summer.
I've seen the son of fermentation chiller threads and the guys with the lightbulb wrapped in tinfoil; but figured those guys are on the extreme ends of fermentation temps; like Alaska and Africa.
