Yes, Champagne can lose its fizz, freshness and flavor over time. An unopened bottle in good storage changes slowly, and an opened one fades fast. Here is what the producers and the Comité Champagne recommend, and where they disagree.
Does Champagne go bad?
The short answer: Yes, but the producers’ figures are recommended drinking windows, not expiration dates. For a standard non-vintage bottle they run from up to 24 months (Moët, Ruinart) to 3 to 5 years (Laurent-Perrier, Taittinger). The clock starts at purchase, release or bottling, depending on the producer. Vintage gets 7 to 10 years or more. Once opened, use a Champagne stopper, refrigerate and plan on 1 to 3 days. TTB’s mandatory wine label checklist lists no expiration date.

Does Champagne Go Bad: At a Glance
Unopened, non-vintage
Recommended windows differ. Moët and Ruinart: up to 24 months for a 75 cl bottle. Laurent-Perrier: 3 to 4 years. Taittinger: 3 to 5 years from bottling
Unopened, vintage
Moët, Ruinart and Veuve Clicquot: 7 to 10 years after purchase or more. Laurent-Perrier: 5 to 10 or more
Opened
Stopper it and refrigerate. The Comité Champagne says 1 to 2 days, Veuve Clicquot about 2, Ruinart up to 48 hours and Laurent-Perrier 1 to 3 days
Expiration date
TTB’s mandatory wine label checklist lists none. These windows are drinking-quality advice, not expiration or safety dates
Best storage
Cool, dark, steady and humid. Producers give 45 to 65°F (Moët, Ruinart) or 50 to 59°F (Comité Champagne, Veuve Clicquot)
Refrigerator
Not needed for long-term storage. A few hours to chill before opening is fine, and an opened bottle goes in the refrigerator
Signs of trouble
A vinegar or sour smell, a leaking bottle or a protruding cork. A dark color or weak fizz is mostly a quality issue
Key Takeaways
Yes, Champagne loses fizz, freshness and flavor over time, slowly when unopened and fast once opened. Heat, light and temperature swings speed up the change.
Producers give recommended drinking windows, not expiration dates. For a non-vintage 75 cl bottle they run from up to 24 months (Moët, Ruinart) to 3 to 5 years (Laurent-Perrier, Taittinger). The clock starts at purchase, release or bottling, depending on the producer.
Moët, Ruinart and Veuve Clicquot give vintage Champagne 7 to 10 years after purchase or more. Moët says there is no benefit in keeping Champagne longer than recommended, and Laurent-Perrier says older does not always mean better.
An opened bottle keeps its fizz about 1 to 3 days with a Champagne stopper. The Comité Champagne says a spoon in the neck does not work.
Champagne doesn’t need refrigeration for long-term storage, and the Comité Champagne and Laurent-Perrier both say the fridge is a poor place to keep it. Chill it a few hours before serving, and refrigerate an opened bottle.
