Why shouldn't I buy a wine fridge?
Are you only an occasional wine drinker? Are you happy enough shopping for bottles from the bargain bin rather than buying expensive drops and then ageing them to perfection? If so, a wine fridge will simply be a waste of money and space.
Like a lot of other appliances, a wine fridge is something we may want, but that few of us actually need. They take up precious space, they can be expensive and they're often energy intensive. If you're not a bona-fide wine enthusiast, or if you simply don't have enough room in your home, you're better off saving your money.
