It's pretty common for liquor and grocery stores to keep champagne in the refrigerator section and many people buy champagne and store it in their fridge from the moment they get home until they drink it. The problem? Well, unless you drink the champagne within three or four days of putting it in the refrigerator, you're actually ruining your sparkling investment.
The science is sound too. The cold, humidless air in the refrigerator dries out the cork, which might not release enough air to let the bubbles get away, but it does release enough air to oxidize the champagne and change the flavor.
So what are you supposed to do? Either put your champagne in the fridge the day before you're ready to drink it or put it in a bucket of cold ice 15-20 minutes before drinking.
