Expiration & Storage Tips
When does champagne expire?
Once opened, champagne quickly loses its sparkle and should ideally be consumed within 3 to 5 days. Thanks to the high acidity and carbonation, it could last up to a week, but the taste will noticeably change as it loses effervescence. Unopened, it depends heavily on the quality of the champagne. Non-vintage champagnes can last anywhere from 3 to 4 years and vintage champagnes can last upwards of 5 to 10 years. Always store the champagne in a cool, dark, and stable environment to extend its shelf life.
How do you tell if champagne is bad?
If your champagne is flat, that is the most common indicator it has gone bad as it has likely lost its carbonation. It should have a lively effervescence when poured into a glass. The color may also change to a deeper hue and the taste can become sour or vinegary. Last but not least, if a foul or musty odor wafts out of the bottle when you first open it, it's a clear sign the champagne has spoiled.
Tips for storing champagne to extend shelf life
• Always store champagne bottles horizontally. This keeps the cork damp, which prevents it from drying out and becoming brittle, leading to air and other contaminants entering the bottle.
• Aim to store your champagne in a cool, dark space. Excess heat and light can damage the champagne and accelerate aging, while cool conditions slow down the aging process and helps maintain its unique flavors.
• Avoid storing champagne in the refrigerator for long periods. While it's crucial to refrigerate before serving for a refreshing taste, long-term storage in a dry fridge can dry out the cork.
• Consider a dedicated wine cooler or cellar for storage if you're a serious champagne collector, as these provide ideal conditions for long-term storage.
• If you've opened a bottle of champagne and didn't finish it, immediately recork it and refrigerate. Consider using a champagne stopper which can seal the bottle tightly and maintain the fizz for longer.
