I currently make and store my wine in the basement. It is a walkout basement so the walls on the back of the house are above grade. I live in the Northeast USA and the temperature in my basement during winter is 61 degrees and 72-75 in the summer (max out at 78-80 degrees). My wife got me a 72-bottle shelving unit for Xmas which is fine for now. I'm concerned about the summer months when the temp can reach 80 degrees. Would I be better off buying a large capacity wine cooler or framing out a small closet in my basement? I have the typical small basement windows (example below) and was thinking about putting one of my portable air conditioners in the closet and running the exhaust hose to the basement window. Not sure which makes more sense...the cost of building and cooling a closet or spending the money upfront for a high capacity wine cooler.
