I'm looking for some advice on a fermentation chamber.
Current situation: Living in N Minn, Summer gets up to 95, Winter gets -30 (both temps in F), I have no basement, fermenting happens in the house on ground level.
So, my problem is 2-fold. 1) My swmbo doesn't like the 15 gal of beer fermenting in 3 containers around the house. 2) In the summer our house gets to abou 75 F - upper end of yeast fermentation temps. THe best place for the chamber is likely the garage unless i can build something that looks nice like furniture. I also have more room in the garage too.
SO, if i build a box style chamber what are the pros and cons of using a fridge vs window air conditioning unit as i see those are the more popular ways to go. Last resort is that i only brew beer in winter months when the house is a more cosnistant 65-68 degrees.
