FOOD STORAGE — HOW LONG CAN YOU KEEP...

• Re-cork the champagne — if a stopper is not available, cover opening with plastic wrap and place a rubber band around the bottle neck to seal plastic tightly.
• Depending on the champagne variety and method used to re-close the bottle, opened champagne may go flat before the time shown above, but will remain safe to drink; consuming the champagne as soon as possible after opening will result in the best taste and appearance.
• Keep refrigerated until ready to drink.
