So, how long does Prosecco last in the fridge after you pop the cork? Generally, an opened bottle of Prosecco will keep its lovely sparkle for about 1 to 3 days when stored properly in the fridge. The main challenge is keeping the fizz! Without a good seal, that delightful bubble goes away quickly.

Grasping Why Prosecco Loses Its Fizz
When a bottle of Prosecco is closed, there’s gas trapped inside. This gas is called carbon dioxide, or CO2. It’s the same gas that makes soda bubbly. This gas is under pressure, forced into the liquid. That’s why you hear that satisfying ‘pop’ when you open the bottle – the gas is rushing out because the pressure outside the bottle is much lower.
Once the bottle is open, the gas inside starts to escape into the air. It keeps leaving the liquid until the amount of gas in the liquid is balanced with the amount of gas in the air above the liquid. Since the air above the liquid in an opened bottle has much less CO2 than the wine does, the gas keeps bubbling out of the wine and floating away. This process is what makes your Prosecco lose its fizz, or go “flat.”
The colder the liquid is, the slower this gas escape happens. This is why keeping opened Prosecco in the fridge helps. The cold temperature makes the gas less eager to leave the liquid. But even in the fridge, the gas will still escape over time, just at a slower rate than if it were left out at room temperature.
Think of it like blowing up a balloon and then letting the air out slowly. The fizz is the air, and the open bottle is like the balloon with the neck open. The tiny bubbles are just the gas making its way out of the wine. Keeping the bottle cold and sealed well slows down how fast that gas escapes.
Deciphering the Duration: How Long Can Prosecco Be Kept?
Knowing that the fizz is the main thing to protect, we can talk more about the typical opened prosecco shelf life. As mentioned, the general rule is 1 to 3 days for keeping some level of sparkle. But let’s break down what that means day by day.
Day 1 After Opening:
If you open a bottle of Prosecco and put a good stopper on it right away and put it in the fridge, it should still be quite bubbly on day 1. The fizz might be just slightly less strong than when you first opened it, but it will still feel very fresh and lively. This is when the opened sparkling wine duration feels closest to a new bottle.
Day 2 After Opening:
On day 2, you will likely notice a clear difference in the bubbles. There will be fewer of them, and they might not rise as quickly or feel as sharp on your tongue. It might still be pleasant to drink, especially if you don’t mind a softer fizz. Some people might find it perfectly fine, while others might feel it has lost too much sparkle for their liking. This is where the ‘how long can prosecco be kept’ question starts to depend more on your personal preference.
Day 3 After Opening:
By day 3, most opened bottles of Prosecco will have lost a significant amount of their fizz, even with a good stopper. The bubbles might be few and far between, or almost gone completely. At this point, it’s often considered “flat” for drinking as is. However, the wine itself is usually still fine to consume from a safety standpoint, it just lacks the defining characteristic of sparkling wine. It’s often still good for mixing in drinks where the fizz isn’t the star, or for cooking.
Beyond Day 3:
After day 3, the chances of there being any noticeable fizz are very low. The wine will taste flat, like a still wine (wine with no bubbles). If it has been stored correctly in the fridge with a stopper, it might still be safe to drink for another day or two as a flat wine, but the flavor might start to change or become less fresh. The ‘is opened prosecco still good’ question after day 3 usually refers to its taste and freshness as a wine, not as a sparkling wine.
It’s important to remember that these are general guidelines. The actual opened prosecco shelf life can be shorter or longer depending on several important factors.
Factors Influencing Prosecco Freshness In Fridge
The 1-3 day timeline is an estimate. How long your opened bottle of Prosecco actually stays enjoyable and fizzy depends a lot on certain things. Let’s look at what makes a difference in prosecco freshness in fridge.
Amount of Prosecco Left in the Bottle
This is a big one. If you have only poured one glass and the bottle is still mostly full, it will keep its fizz much better and for longer than if you have only a little bit left at the bottom.
- Mostly Full Bottle: When the bottle is full, there is less empty space between the wine and the stopper. This means there’s less room for the CO2 gas to escape into. The gas pressure above the liquid stays higher, which helps keep the gas dissolved in the wine.
- Half Full or Less Bottle: With more empty space, the gas from the wine has a larger area to fill. The pressure above the liquid drops faster, and more CO2 escapes from the wine to try and fill that space. This makes the wine go flat much faster.
Think of it like a soda bottle. A nearly empty soda goes flat way quicker than a new bottle you just took a sip from. The same idea applies to opened sparkling wine duration.
The Type and Effectiveness of the Stopper Used
This is perhaps the most important factor in keeping prosecco bubbly. The regular cork that came with the bottle is designed for a one-time seal under high pressure. Once you pull it out, it expands slightly and doesn’t fit back in tightly enough to hold the pressure and gas in effectively. Putting the original cork back in, even upside down, does very little to stop the fizz from escaping.
This is where a good prosecco stopper effectiveness comes into play. Special stoppers designed for sparkling wine create a much tighter seal around the bottle neck. These stoppers usually have a rubber seal and a clamp mechanism that holds them firmly in place against the bottle opening.
- Good Sparkling Wine Stopper: These stoppers are specifically made to create an airtight seal, trapping the CO2 gas inside and maintaining the pressure. Using one of these can significantly extend how long your Prosecco stays fizzy, helping you reach the 2 or 3-day mark with decent bubbles.
- Original Cork: As mentioned, this does not seal well. If you just put the original cork back in, your Prosecco will likely be noticeably flat by the next morning.
- Other Improvised Stoppers (e.g., plastic wrap and rubber band): These are generally not effective enough to keep the fizz in. They might prevent spills, but they won’t create the pressure seal needed to preserve the bubbles.
Investing in a good quality sparkling wine stopper is the best thing you can do if you often don’t finish a bottle in one go. It directly impacts the keeping prosecco bubbly success.
Constant Low Temperature
Keeping the opened bottle in the fridge is essential for storing opened prosecco. As explained before, cold temperatures slow down the rate at which the CO2 gas escapes from the liquid.
- In the Fridge (around 35-40°F or 2-4°C): The cold helps keep the gas dissolved in the wine. This is the proper way for storing opened prosecco.
- Left Out at Room Temperature: If you open a bottle, pour a glass, and then leave the bottle sitting on the counter for hours before putting it back in the fridge, you will lose a lot of fizz during that time. The warmer the wine gets, the faster the gas escapes. Even with a good stopper, temperature changes matter. Try to get the bottle back into the cold fridge as soon as possible after pouring.
- Putting it Back in the Fridge Door: While it’s cold, the fridge door is opened and closed more often than the main shelves. This means the temperature there can change slightly more. For the best prosecco freshness in fridge, a spot on a main shelf towards the back (but not so far back it freezes!) can be ideal, as long as the bottle fits safely.
Original Quality and Amount of Fizz
Some Proseccos naturally have more dissolved CO2 than others when bottled. This can be due to how they were made (Charmat method variations) or the specific style (e.g., Conegliano Valdobbiadene Superiore might have slightly more pressure than a basic Prosecco Frizzante, though Frizzante has less pressure initially anyway).
A Prosecco that started with a very strong, lively fizz might simply have more gas to lose before it seems “flat.” It might therefore last a little longer than a Prosecco that had a softer, less intense fizz from the beginning. However, this factor is less important than the amount left in the bottle and the stopper used.
How You Handle the Bottle
Shaking or moving the opened bottle roughly will make the gas escape much faster. When you pour, do so gently. When you put the stopper on, do it carefully. When you put it in the fridge, don’t just shove it in. Gentle handling helps the bubbles stay in the wine.
Keeping Prosecco Bubbly: Best Practices for Storing Opened Prosecco
Knowing what makes Prosecco lose its fizz helps us figure out the best ways for storing opened prosecco to keep it bubbly for as long as possible. Here are the top tips for maximum opened prosecco shelf life.
Use a Proper Sparkling Wine Stopper
This is the most important tip for keeping prosecco bubbly. Forget the original cork or any makeshift solutions. You need a stopper designed for the job.
- What to Look For: A good sparkling wine stopper will have a rubber seal that fits snugly around or into the neck of the bottle. It will also have a clamping mechanism, usually made of metal or sturdy plastic, that hooks under the lip of the bottle and snaps closed over the stopper. This clamp holds the stopper firmly in place, creating a strong, airtight, and pressure-resistant seal.
- Why They Work: These stoppers trap the escaping CO2 gas above the wine, increasing the pressure in the small space between the wine and the stopper. This higher pressure pushes back down on the wine, making it harder for more gas to escape. This significantly improves prosecco stopper effectiveness compared to other methods.
- Where to Buy: You can find these stoppers at wine shops, kitchen supply stores, and online retailers. They are usually not very expensive, perhaps $5 to $20, and are a worthwhile investment if you enjoy sparkling wine but don’t always finish the bottle.
- How to Use: After pouring your last glass, insert the rubber part of the stopper into or onto the bottle neck. Then, bring the clamp arms down and hook them under the lip of the bottle. Finally, snap the top part of the clamp down firmly to seal the stopper. Make sure it feels secure.
Store Immediately and Keep it Cold
As soon as you’ve poured the last glass you plan to drink for the moment, put the stopper on the bottle and put it straight back into the fridge. Don’t leave it sitting out on the counter for a “little while.” The longer it’s at room temperature, the faster the fizz disappears.
Keep the bottle upright in the fridge. This minimizes the surface area of the wine exposed to the air/gas pocket under the stopper. Placing it in the body of the fridge, rather than the door, can help maintain a more constant, colder temperature.
Avoid Temperature Swings
Once the bottle is in the fridge, try to keep it there until you’re ready to pour another glass. Taking it out, letting it warm up, and then putting it back in the fridge causes temperature changes that can encourage the gas to escape. Pour a glass quickly and get the bottle back into the cold.
Minimize the Air Space (If Possible)
While not always practical for everyday use, if you have a very small amount of expensive sparkling wine left, sometimes people transfer it very gently to a smaller bottle (like a clean, dry soda bottle or a half-bottle of sparkling wine bottle) and seal it tightly. This reduces the empty space, potentially preserving fizz a little longer. However, this risks losing fizz during the transfer and isn’t necessary for most Prosecco bottles that will be finished within a day or two with a proper stopper. For typical opened prosecco shelf life, a good stopper on the original bottle is sufficient.
Don’t Rely on Old Tricks
You might have heard old wives’ tales about putting a silver spoon in the bottle neck. This does not work to keep the fizz in. It might cool the neck slightly, but it does nothing to create the necessary airtight, pressure-resistant seal needed to trap the CO2 gas. Save your silverware for eating!
Following these tips, especially using a good stopper and keeping the bottle cold, are the best ways for storing opened prosecco and maximizing its opened sparkling wine duration.
Is Opened Prosecco Still Good When The Fizz Is Gone?
Let’s say you’ve had an opened bottle in the fridge for a few days, and it’s lost most or all of its sparkle. Is it still good? This question often comes up when discussing ‘is opened prosecco still good’.
The answer is usually yes, it is still good from a safety point of view, as long as it hasn’t actually gone bad (we’ll cover signs of spoilage next). The loss of fizz doesn’t mean the wine is unsafe to drink; it just means it has changed its form from sparkling wine to flat, or “still,” wine.
A Prosecco that has gone flat will taste different than a fresh one. The bubbles contribute to the flavor and texture, making it feel lighter and carrying aromas to your nose. Without the fizz, it will taste more like a regular dry white wine. The specific flavors might seem less intense or slightly different without the sparkle.
Whether it’s still “good” in terms of enjoyment is up to your personal taste. Some people don’t mind drinking flat Prosecco. Others find it less pleasant. However, even if you don’t want to drink it flat, it’s still perfectly good for other uses.
This is a key point: losing fizz does not equal spoiling. It’s just a change in the wine’s character.
Signs of Spoiled Prosecco: When It’s Really Not Good
While Prosecco going flat is normal after opening, there are times when the wine actually spoils and should not be consumed. Knowing the signs of spoiled prosecco is important for safety and avoiding unpleasant tastes.
Spoilage usually happens when the wine has been exposed to too much air for too long, or if it wasn’t stored properly (like being left out at room temperature for days). Air can introduce bacteria or allow chemical reactions that turn the wine bad.
Here are the main signs of spoiled prosecco:
- Vinegary Smell: This is the most common sign. Wine can turn into vinegar when exposed to air and certain bacteria (Acetobacter). If your Prosecco smells strongly like vinegar, nail polish remover, or something sharp and sour, it’s spoiled. A fresh Prosecco should smell fruity, floral, or maybe a little like yeast or bread.
- Change in Color: Prosecco is typically a pale straw yellow color, sometimes with greenish hints. If your opened bottle has turned a darker yellow, golden, or even brownish color, it’s a sign of oxidation and spoilage.
- Cloudiness or Sediment: Fresh Prosecco should be clear. If the liquid looks cloudy, hazy, or you see weird floaty bits that weren’t there when you opened it, it could be a sign of microbial growth or other spoilage. A tiny bit of sediment is sometimes possible in certain wines, but widespread cloudiness is a red flag.
- “Off” or Unpleasant Flavors: If you take a sip and it tastes weirdly sour (beyond the normal acidity), bitter, medicinal, or just generally “off” and unpleasant, trust your taste buds. Spoiled wine tastes bad. It might taste vinegary, overly nutty (in a bad way), or just bland and oxidized.
- Lack of Any Pleasant Aroma: Instead of fresh fruit or floral smells, spoiled Prosecco might smell musty, like wet cardboard, or just generally stale and unpleasant.
If you notice any of these signs, it’s best not to drink the Prosecco. While a little oxidation might just make it taste flat and dull (not truly spoiled), a strong vinegar smell or cloudiness means it has definitely gone bad. It’s safer to discard it. The question ‘is opened prosecco still good’ shifts from “does it still have fizz?” to “is it safe and pleasant to drink?” when you see these signs.
Proper storage, including keeping it cold and using a good stopper, greatly reduces the risk of spoilage and maximizes the opened sparkling wine duration for quality.
Beyond Drinking: Using Flat Prosecco
Even if your opened Prosecco has gone completely flat but hasn’t shown signs of spoilage, it’s still perfectly good for other uses. Don’t pour it down the drain! Using flat Prosecco is a great way to avoid waste and add flavor to food and other drinks.
Here are some ideas for using Prosecco that has lost its fizz:
- Cooking: Flat Prosecco can be used in many recipes that call for white wine.
- Risotto: It adds a lovely depth of flavor to creamy risotto dishes. Just add it at the step where you would normally add white wine and let it cook down.
- Sauces: Use it to make pan sauces for chicken or fish. Deglaze the pan after cooking meat or fish with a splash of flat Prosecco.
- Steaming: Use it as a liquid for steaming mussels or clams.
- Poaching: You can gently poach fish or fruit in flat Prosecco.
- Marinades: Add it to marinades for meat or poultry.
- Cocktails: Even without its own fizz, flat Prosecco can be a base for cocktails.
- Mimosas or Bellinis: These drinks are often made with fruit juice and sparkling wine. If your Prosecco is flat, you can still use it and get the sparkle from the orange juice or peach puree blending with it, or even add a splash of sparkling water or club soda.
- Spritzers: Combine flat Prosecco with sparkling water, soda water, or a flavored sparkling beverage for a refreshing drink.
- Punch: Use it as part of the liquid base for a party punch.
- Wine Vinegar: If you’re feeling adventurous, you can leave a bottle of flat Prosecco open and let it intentionally turn into Prosecco vinegar. This requires specific conditions and a “mother” culture, so it’s not as simple as just leaving it out, but it’s a possibility for the truly dedicated!
Using flat Prosecco in cooking or mixing drinks is a smart way to ensure zero waste and still enjoy the flavors of the wine, even when the bubbles are gone. It extends the useful life of the wine far beyond its opened sparkling wine duration for drinking as is.
How Long Can Prosecco Be Kept (Unopened)?
This blog post is mainly about opened bottles, but it’s helpful to touch briefly on unopened Prosecco storage.
Unlike fine still wines that can age for many years, Prosecco is generally meant to be enjoyed young and fresh. The lovely fruity and floral flavors are best enjoyed within a year or two of bottling. Most non-vintage Proseccos (the majority you’ll find) don’t have a specific “best by” date, but drinking them within 12-18 months of purchase is a good rule of thumb for enjoying them at their peak freshness and fizz.
Storing unopened Prosecco correctly also matters. Keep bottles on their side (to keep the cork moist and sealed) or upright if they have a crown cap or synthetic stopper. Store them in a cool, dark place with a constant temperature (like a cellar or a wine fridge), away from direct sunlight or heat sources. Fluctuations in temperature are bad for wine, sparkling or not.
While an unopened bottle won’t spoil in the sense of turning to vinegar after a few years (unless the seal fails), it will likely lose its freshness, vibrancy, and eventually, its fizz. It won’t taste the way it was intended.
Summarizing Opened Prosecco Shelf Life
Let’s pull together the key points about how long opened Prosecco lasts in the fridge.
| Factor | Impact on Fizz & Freshness | Best Practice | Opened Shelf Life (Estimate) |
|---|---|---|---|
| Stopper Used | Original cork = fast fizz loss; Proper stopper = slower loss | Use a dedicated sparkling wine stopper | 1-3 days (with good stopper) |
| Amount Left | Fuller bottle = slower fizz loss; Less wine = faster loss | Finish as much as possible; Use a good stopper | Varies based on fill level |
| Temperature | Cold = slower fizz loss; Warm = faster fizz loss | Store immediately in the fridge (35-40°F) | Cold storage is essential |
| Handling | Gentle = keeps fizz; Rough = loses fizz | Handle bottle and pour gently | Gentle handling helps |
| Original Fizz | Higher initial fizz might last slightly longer | Less control over this, focus on storage factors | Minor impact |
To maximize opened sparkling wine duration and keep your prosecco bubbly:
1. Use a good quality sparkling wine stopper with a tight seal.
2. Put the stopper on immediately after pouring your last glass.
3. Store the bottle upright in the coldest part of your fridge (not the door).
4. Handle the bottle gently.
Even with the best care, expect the fizz to noticeably decrease after day 1 and be largely gone by day 3. The wine itself, however, will usually remain safe to drink as a flat wine for a few days longer, provided it shows none of the signs of spoiled prosecco.
FAQ: More Questions About Opened Prosecco
Here are answers to some common questions about keeping opened Prosecco.
Q: Can I put opened Prosecco in the freezer to keep the bubbles?
A: No, you should never put wine, especially sparkling wine, in the freezer. The liquid will freeze, expand, and shatter the glass bottle, creating a dangerous mess. Keep it in the fridge, not the freezer.
Q: What if I don’t have a proper stopper?
A: Putting the original cork back in is the next best thing, but understand that it will do very little to keep the fizz. Your Prosecco will likely be quite flat within hours or overnight. Plastic wrap secured with a rubber band is also not very effective. For the best results and opened prosecco shelf life, get a proper stopper. If you don’t have one and only have a little wine left, plan to finish it quickly or use it for cooking the next day.
Q: Does adding a spoon really help?
A: No, putting a spoon in the neck of the bottle is a myth and does not help keep the fizz in Prosecco or any sparkling wine. The science behind it is not sound.
Q: Can I use a vacuum pump stopper on Prosecco?
A: No, vacuum pumps are designed for still wines. They remove air from the bottle to prevent oxidation. For sparkling wine, you want to keep the CO2 gas in the bottle under pressure, not remove it. Using a vacuum pump would pull the bubbles out of the Prosecco, making it go flat even faster. Only use stoppers specifically made for sparkling wine.
Q: How long can opened Prosecco sit out at room temperature?
A: Not long if you want to keep the fizz. The warmer temperature makes the gas escape much faster. If you leave it out for even an hour or two after opening, you’ll lose a noticeable amount of bubbles, even with a stopper. It’s best to get it back in the fridge as soon as possible after pouring.
Q: If my Prosecco has lost its fizz but isn’t spoiled, how long can I keep it in the fridge as a flat wine?
A: If it’s just lost its fizz but shows no signs of spoilage (vinegar smell, color change, cloudiness), you can likely keep it in the fridge for another 1-3 days as a flat wine. However, its fresh flavors will start to fade, and oxidation will slowly occur. It’s best to use it for cooking or mixing within a couple of days of it going flat.
Q: Does the price of the Prosecco affect how long it lasts opened?
A: Generally, no. While a higher quality Prosecco might have a slightly finer or more persistent initial bubble, the rate at which the CO2 escapes after opening is primarily determined by the storage method (stopper, temperature, amount left), not the price or specific brand. A good storage method is crucial regardless of how much you paid for the bottle.
Q: Is it okay to drink slightly flat Prosecco?
A: Absolutely! If it has lost some fizz but still tastes good and shows no signs of spoilage, it’s perfectly safe and often still enjoyable to drink. It just won’t have the lively sparkle of a freshly opened bottle. Your preference dictates whether you enjoy it.
Keeping Prosecco bubbly after opening is achievable with the right tools and habits. While its opened sparkling wine duration is limited, knowing how to store it and recognizing the signs of spoilage means you can enjoy every bottle to its fullest, whether bubbly or flat and used in a delicious recipe.
