If you are a serious connoisseur or wine collector, a wine preservation system might be in order. The Wine Saver HOME is a wine-by-the-glass preservation system for home use.

This system is small and easy to use. You can preserve up to three bottles of wine at once. Designed much like the commercial systems used in restaurants, the Wine Saver HOME uses argon gas to preserve bottles of wine for up to three weeks after opening.
