Do you own Bordeaux that you want to cellar for 20 years, white Hermitage you wish to keep for 10?
You better buy a refrigerated wine cellar unit. If you intend keeping a couple of thousand dollars worth of wine, the 200-300 investment is well worth it.
Is your collection whites you are going to drink in a year and reds you are keeping 2-3? Keep the whites in the fridge and don't worry about the reds.
