Does Champagne Go Bad? - KnowWines

Check out our full review on the Repour Wine Saver, including our field test on a bottle of champagne.

For both the Kloveo and the Repour, bottles should stay standing up in the refrigerator once the enclosure has been placed on the bottle opening.

How do I keep an open bottle of champagne bubbly?

Regardless of the enclosure, the reason we recommend keeping an opened champagne or sparkling wine in the refrigerator is to slow down the loss of carbon dioxide. Carbon dioxide is more soluble in wine (and any other beverage) when temperatures are lower.

Can old champagne make me sick?

Old champagne (or any sparkling wine for that matter) will not make you sick (unless of course, you overindulge). If you are concerned about the quality of an older wine, assess it just as you would a container of milk you’ve had opened a few days in your refrigerator. If it looks unpleasant, smells unpleasant, and a few small drops on your tongue taste unpleasant, then yes, the wine has gone bad but won’t make you sick.

How long can I keep an open bottle of champagne in the refrigerator?

We recommend drinking any remnant champagne within 24 hours. However, when using the Repour Wine Saver (affiliate link), we’ve had some champagne that was still bubbly and fresh enough to drink three days later.

Will champagne freeze?

Yes, champagne (and any other sparkling wine) can freeze.

It is generally not a good idea to place sparkling wines in the freezer simply for the reason that one can forget the wine in the freezer. Upon opening the freezer door the next day, you can be greeted with a wine popsicle - and typically the cork has been compromised or pushed out of the bottle. While one can thaw and drink most still wines, sparkling wines often lose some of their bubbles after being frozen.

How long can I keep champagne or sparkling wine unopened? Does champagne expire?

When purchasing any sparkling wine or non-vintage champagne, a good rule of thumb is that it is still fresh and effervescent a few years after bottling. If you can’t find the year when the wine was bottled on the label, ask the wine bottle shop owner or staff. Some premium and luxury sparkling wines and non-vintage champagnes can be stored even longer than a few years. If your wine is vintage champagne (meaning that there is a vintage, or year, on the front of the bottle) these wines can age 15 years or more.
