Hah, back from the dead, but I was thinking about this same thing earlier. I want to brew an Oktoberfest and lager it until Sept. I can lager it in the keg in my keggerator, but fermentation is the main issue. The cellar is about 58*F right now and will only get warmer. I was considering a swamp cooler, a tub of water with the fermenter in it, replacing jugs of ice every 12 hrs. OR, using a Cali or San Fran Lager yeast, which can ferment warmer. I think I may try the swamp cooler. I just hope the temp doesn't fluctuate too much.
