So I've been tossing around the idea of using the freely available freezing cold air outside to my advantage, to do some lagering. My interest was dramatically increased when I realized that I can fit two cornies in my fermentation cabinet which, for obvious reasons, has been in disuse since autumn.
I'm thinking I could build some kind of simple air duct, that would go in a window, to draw in cold air from outside using fan controlled by a thermostat, through some tubing, into the cabinet.
My biggest question is - is stable temperature critical for lagers, or does it mainly just have to be "cold enough"? I live in Maine, so it's usually pretty cold and thus maintaining a stable temp should not be hard, but it's certainly possible to have a warm day here and there. I imagine that there'd be no real threat of it ever getting above maybe 50-something, but I don't know for sure.
Any thoughts?
