We're moving in January to a house with no basement and i have about 300 bottles of wine to store. This is in Waupaca, Wisconsin, very cold in winter and pretty mild in summer. The house has a room on the northwest corner that will be shaded in the summer, but unless i put in a window air conditioner it will be in the seventies during the summer. In the winter i can close off the heat and keep it cool. the house does have a 4' deep dry crawl space that is heated enough to keep the pipes from freezing, but i can't see putting that much wine in there. so my question is as we remodel the house i could insulate the interior walls of that room and run a small AC unit, but is that going to be expensive if i shoot for about 60 degrees? Or should i try to make a smaller storage area so i don't have to cool the whole room.
