Champagne is synonymous with celebration, but what happens when the party ends and you still have some bubbly left in the bottle? Whether you’re saving an unfinished bottle for another occasion or simply curious about how long the sparkling wine remains fresh, this guide will answer all your questions.
We’ll explore everything from how long an open bottle of champagne lasts, the best storage methods, how to tell when champagne has gone bad, and tips for preserving the quality and flavor of your champagne. Let’s dive in and learn how to make the most of every last drop.
How Long Does Champagne Last Once Opened?
Champagne’s shelf life changes dramatically once opened. Unlike still wines, champagne loses its bubbles quickly and can become flat if not stored properly. The sparkling nature of champagne relies on carbon dioxide (CO2), which is released when the bottle is opened. Here’s a general timeline for how long an open bottle of champagne lasts:
Without a stopper: Champagne starts to go flat within a few hours. If left uncovered, an open bottle will lose most of its carbonation by the next day.
With a stopper: When you use a champagne stopper, you can extend the freshness of your champagne for up to 3-5 days. The bubbles will start to diminish after the first day, but it will still retain some effervescence.
Refrigerated vs. Room Temperature: Storing an open bottle of champagne in the refrigerator helps to slow down the loss of bubbles. Room temperature storage accelerates the process, causing the champagne to go flat faster.
Why Does Champagne Lose Its Bubbles?
The key to champagne’s delightful fizz is carbonation. When a bottle is sealed, the carbon dioxide is trapped inside the liquid under pressure. Once you open the bottle, the gas begins to escape, and the bubbles start to diminish. This process accelerates when the champagne is exposed to air.
Air exposure: The more air that comes into contact with the champagne, the quicker it loses its bubbles.
Temperature: Champagne loses carbonation more quickly at warmer temperatures. That’s why it’s best to store it in the refrigerator after opening.
Volume in the bottle: The less champagne left in the bottle, the faster it will go flat. This is because there is more air space, which causes the carbonation to escape more rapidly.
The Importance of Using a Champagne Stopper
One of the simplest and most effective ways to extend the life of an open bottle of champagne is by using a champagne stopper. These specially designed stoppers create an airtight seal that helps preserve the bubbles for a few extra days. Here’s why it works:
Airtight Seal: A champagne stopper locks in the carbonation and prevents excess air from entering the bottle, which slows the process of going flat.
Pressure Maintenance: The stopper helps to maintain the pressure inside the bottle, which keeps the bubbles intact for a longer period.
Ease of Use: Champagne stoppers are easy to use and typically affordable, making them a great investment for champagne lovers.

How to Store an Open Bottle of Champagne
Proper storage plays a critical role in how long an open bottle of champagne will last. Here are some tips for storing champagne to preserve its quality and freshness:
Refrigeration: After opening, always store champagne in the refrigerator. The cooler temperature helps slow down the loss of bubbles and keeps the flavor fresh.
Use a Champagne Stopper: As mentioned earlier, a champagne stopper is essential for keeping an open bottle fresh. The stopper creates an airtight seal and helps maintain the pressure inside the bottle.
Keep Upright: Store your open champagne bottle upright in the refrigerator. This reduces the surface area of the champagne that’s exposed to air, which helps preserve the carbonation for longer.
Avoid Freezing: While it may seem tempting to store champagne in the freezer, this can damage both the flavor and the bubbles. Freezing can cause the liquid to expand, which may result in the bottle cracking or exploding.
Signs That Champagne Has Gone Bad
It’s important to know how to tell when champagne has gone bad, especially if you’re planning to drink from an open bottle that’s been stored for a few days. Here are some telltale signs that your champagne has passed its prime:
Flat Bubbles: If the champagne has gone flat and no longer has its signature fizz, it’s a clear sign that it has lost its carbonation.
Change in Color: Champagne should be clear and golden. If the liquid appears cloudy, dull, or has darkened significantly, it may have gone bad.
Off Smell: A sour or musty smell is a strong indicator that the champagne has spoiled. Champagne should have a fresh, fruity, and yeasty aroma.
Unpleasant Taste: Spoiled champagne will have a vinegary or off-taste. If the flavor is unpleasant, it’s best to discard the champagne.
Can You Drink Flat Champagne?
While flat champagne won’t harm you, it may not provide the same enjoyable experience. The lack of bubbles can make the champagne taste dull, and it may have lost some of its bright, fruity flavors. However, there are creative ways to use flat champagne if you don’t want to waste it:
Cocktails: Use flat champagne as a base for cocktails like a French 75, where the fizz can be replaced with soda water or tonic.
Cooking: Flat champagne can be used in recipes that call for wine, such as risotto, pan sauces, or marinades.
Champagne Syrup: You can create a simple syrup by reducing flat champagne with sugar, which can then be used in cocktails or desserts.
How to Maximize the Life of Your Champagne
If you want to maximize the lifespan of your open champagne bottle, here are a few tips:
Use a champagne stopper immediately after opening the bottle to seal in as much carbonation as possible.
Store the champagne in the coldest part of your refrigerator, ideally between 45-50°F (7-10°C). This will slow down the release of CO2 and help retain the bubbles.
Avoid shaking or agitating the bottle, as this can cause the remaining carbonation to escape more quickly.
Try to finish the bottle within 1-3 days to enjoy the best quality and freshness of the champagne.
Can You Recarbonate Champagne?
If your champagne has gone flat, you might wonder if there’s a way to reintroduce bubbles. Unfortunately, once champagne has lost its carbonation, it’s nearly impossible to restore the original effervescence. However, there are a few tricks that some people claim can help:
Add a Raisin: Some say that dropping a raisin into a flat bottle of champagne can help revive the bubbles. The theory is that the raisin attracts the remaining carbon dioxide in the bottle, which can create a small burst of bubbles. While this might provide a temporary fix, it’s unlikely to restore the full carbonation of the champagne.
Use Soda Water: If you want to add fizz to a flat mimosa, you can pour a small amount of soda water into the glass. This won’t replicate the texture of champagne, but it will add some effervescence.
The Role of Vintage vs. Non-Vintage Champagne in Longevity
When it comes to the longevity of an open bottle, the type of champagne matters. Here’s a brief overview of how vintage and non-vintage champagnes differ in terms of how long they last once opened:
Vintage Champagne: Vintage champagnes are made from grapes harvested in a single year and tend to be more complex and robust in flavor. Because of their fuller body and structure, they may retain their flavor better than non-vintage champagnes after being opened. However, they still lose their bubbles at the same rate.
Non-Vintage Champagne: Non-vintage champagnes are blends of grapes from multiple years. They are typically lighter and fruitier, and may not hold up as well after being opened compared to vintage champagnes.
The Bottom Line: How Long Does an Open Bottle of Champagne Last?
An open bottle of champagne lasts between 3-5 days with proper storage and a champagne stopper. However, the bubbles will begin to fade after the first day, and the champagne may not taste as fresh after a few days. To ensure you enjoy the best quality, it’s recommended to consume an open bottle of champagne within 1-2 days.
If you’re unable to finish the bottle in one sitting, using a champagne stopper and refrigerating the bottle can help preserve the flavor and bubbles for a little longer. Remember that flat champagne can still be repurposed in cocktails or cooking, so don’t let it go to waste!
Enjoying champagne is about savoring the moment, and with the right care and storage, you can make the most of every bottle, whether it’s freshly opened or a few days old. Cheers!
