How long does champagne last? Keep it chilled!

Champagne is synonymous with celebration and is often popped open to commemorate special occasions. However, it is not always practical to finish a bottle in one sitting. So how long does champagne last? And what is the best way to store it to ensure it remains fresh for as long as possible?

What affects how long champagne lasts?

Several factors affect how long a bottle of champagne lasts:

  • Type of champagne: Different types of champagne have different aging potential. Vintage champagne can last for several decades, whereas non-vintage champagne is best consumed within a year or two of purchase.
  • Storage conditions: Temperature, humidity, and light exposure significantly impact how long champagne lasts. Champagne should be stored in a cool, dark place, away from direct sunlight and heat sources.
  • Bottle size and type: Magnum bottles and champagne with natural cork stoppers tend to age more slowly due to a slower oxygen exchange rate.

How long does champagne last in the fridge?

The best way to extend the lifespan of champagne is to keep it in the fridge. A bottle of non-vintage champagne stored in the fridge at around 4°C can last for up to three days after opening. However, it is important to keep the bottle tightly sealed to prevent carbonation loss.

How long does champagne last unopened?

When stored correctly, unopened champagne can last for several years. Non-vintage champagne should be consumed within two years of purchase, whereas vintage champagne can last for several decades. However, it is worth noting that champagne does not improve with age and should be consumed within its recommended best-before date.

How should champagne be stored?

Champagne should be stored in a cool, dark place, away from direct sunlight and heat sources. A wine cellar or a cool, dry closet are ideal storage locations. Keeping the bottle horizontal helps keep the cork moist which ensures a tight seal and prevents air from entering the bottle.


Humidity is also an essential factor to consider when storing champagne. An overly dry environment will cause the cork to shrink, while an overly humid one will cause the cork to become moldy. A humidity level of around 60-70% is ideal for champagne storage.


Light exposure can also affect champagne’s lifespan. UV rays can break down the wine and cause chemical reactions that negatively impact the taste and aroma. Keep champagne bottles away from direct sunlight, and store them in a dark place.

Can you freeze champagne?

While it is not recommended to freeze champagne, it can be done in a pinch. When freezing champagne, it is essential to take safety measures to prevent the bottle from exploding due to carbonation buildup caused by the expansion of the liquid. Before freezing the bottle, pour a small amount out to create room for the expansion. Also, store the bottle in a sealed plastic bag, and do not freeze for more than two hours.

What are the signs that champagne has gone bad?

Here are some signs to be aware of when considering if your champagne has gone bad:

  • Oxidation: A stale, cardboard-like or musty odor, and taste, is often a sign of oxidation, which can occur when the champagne is exposed to air.
  • Foul Smell: The champagne smells like wet cardboard, vinegar, or rotten eggs.
  • No fizz: A lack of bubbles can be a sign that the champagne has gone flat.
  • Odd color:The wine inside the bottle has an unusual color or appears cloudy.

The Bottom Line

The lifespan of a bottle of champagne is determined by several factors such as the type of champagne, storage conditions, and exposure to light. Storing the champagne in the fridge is the best way to extend its lifespan after opening. Unopened champagne can last for several years when stored in optimal conditions.

As with any foodstuff, use your senses to determine if champagne has gone bad before consuming it.
