How Long Does Unopened Prosecco Last

Prosecco is a popular sparkling wine that is enjoyed all year round. But how long does it last once it has been opened? Or, if you don’t want to open it yet, how long can you store an unopened bottle of Prosecco? The answer may surprise you. This article will explore the shelf life of both opened and unopened Prosecco, so you can enjoy your favorite bubbly for as long as possible!

Unopened Prosecco can last up to two years if stored in ideal conditions, such as a cool, dark room with a consistent temperature and away from direct sunlight.

Does Prosecco Expire?

Prosecco is an Italian sparkling wine made from Glera grapes. It is one of the most popular sparkling wines in the world and is widely available. But does it ever go bad? Yes, Prosecco does expire and should be consumed within two years of its production date for optimal flavor. After this time, the flavor will start to decline as the carbonation dissipates and the aromas diminish.

Prosecco will remain safe to drink if stored properly, but it will not taste as good after two years. As with any bottle of wine, it should be kept away from direct sunlight and stored at a consistent temperature between 50-60 degrees Fahrenheit in a dark place. Once opened, it should be consumed within four days to avoid spoilage.

One way to tell if your Prosecco has gone bad is to look at the color of the liquid. If it has changed from a light yellow-gold hue to a darker brownish shade, then it’s time to discard it. You may also notice that the bubbles have reduced or become more sluggish than usual.

Another indication that your Prosecco may not be in its best condition is if there is sediment on the bottom of the bottle or along the sides when you pour it into a glass. This could indicate that some of the wine has gone off and is best avoided for safety reasons.

In short, Prosecco does expire and should be enjoyed within two years for optimal flavor and enjoyment. Be sure to store your bottles properly and check for signs of spoilage before consuming any wine beyond this time frame!

Storage Temperature

Prosecco shelf life is directly affected by storage temperature. Prosecco must be stored at a cool and consistent temperature between 8-10°C (46-50°F). If it is exposed to temperatures above 10°C (50°F), the shelf life will be significantly reduced. It is important to store Prosecco away from direct sunlight and other sources of heat, as this will cause it to go off quickly.


Prosecco should be stored in an airtight container or bottle so that oxygen cannot get in and spoil the taste. Properly sealed bottles can keep the Prosecco fresh for up to a year, while opened bottles should be consumed within a few days, as the flavor and quality of the wine will start to deteriorate soon after opening.


Sulfites are compounds found in all wines that help preserve them and prevent oxidation. The amount of sulfites in Prosecco can vary greatly depending on the type of grape used to make it and how it was processed. Generally speaking, Prosecco with higher levels of sulfites will have a longer shelf life than those with lower levels.


Clarity is also an important factor when considering the shelf life of Prosecco. Cloudier wines tend to have a shorter shelf life than those that are clear and bright. It is important to store Prosecco in a dark place, as light can cause it to oxidize faster, resulting in a shorter shelf life.

Effects of Temperature Change on Unopened Prosecco

Prosecco is a type of sparkling wine that has become increasingly popular in recent years. It is typically stored at a cool temperature, and it’s important to understand how changes in temperature can affect its quality. If an unopened bottle of Prosecco is exposed to temperatures above 45°F (7°C), the quality and taste of the wine can be affected. This is because the bottle can become pressurized, which will cause the carbonation to escape and the flavor to change. As a result, it’s important to store any unopened bottles of Prosecco in a cool place and avoid exposing them to temperatures higher than 45°F (7°C).

If an unopened bottle of Prosecco is exposed to temperatures below 40°F (4°C), then it could become frozen. This will cause the bottle to burst due to the pressure from the carbonation, which will lead to a loss of flavor and texture. Additionally, when freezing temperatures are reached, some of the alcohol content may be lost from evaporation. To avoid this issue, it’s important to store any unopened bottles of Prosecco away from freezing temperatures.

In conclusion, storing unopened bottles of Prosecco at temperatures between 40-45°F (4-7°C) is ideal for preserving its quality and taste. Exposure to higher or lower temperatures can affect its flavor and texture, so it’s important to take steps to ensure that your bottles are kept at the right temperature.

Effects of Light Exposure on Unopened Prosecco

The effects of light exposure on unopened Prosecco can be significant, as it is a sparkling wine produced in Italy. Light can cause the wine to become “lightstruck”, meaning that it will have an unpleasant odor and taste. This is due to a reaction between the molecules in the wine and ultraviolet light, which produces a compound called “skunky” thiols. If left exposed for too long, these compounds can cause the Prosecco to have a strong, unpleasant odor and flavor.

It is important to store unopened Prosecco in a cool, dark place away from direct sunlight or other sources of UV light. Even if stored properly, this type of sparkling wine should be consumed within three months after purchase. Beyond that time frame, it is likely that the Prosecco has been exposed to too much light and could potentially develop off-flavors or aromas as a result.

In addition to avoiding light exposure, unopened Prosecco should also be kept away from heat sources such as radiators or stoves. Heat can cause the bottle to expand and contract, which could potentially affect the pressure inside and lead to cork failure or leakage. It is also recommended that bottles are stored lying down in order to keep the cork moist and ensure proper sealing.

Ultimately, proper storage conditions are essential for preserving the quality of unopened Prosecco. Keeping it out of direct sunlight and away from heat sources will help ensure that it maintains its freshness and flavor for as long as possible before being opened and enjoyed.

Proper Storage Techniques for Unopened Prosecco

Prosecco is a sparkling wine that should be stored properly in order to maintain its quality and flavor. Unopened bottles of Prosecco should be stored in a cool, dry place away from direct sunlight and strong odors. The ideal temperature for storing unopened Prosecco is between 41-46 degrees Fahrenheit. Storing Prosecco in temperatures higher than this can damage the flavor and reduce its shelf life. Additionally, unopened bottles of Prosecco should be stored upright so that the cork remains moist and prevents air from entering the bottle.

It is also important to store unopened bottles of Prosecco away from extreme temperature fluctuations as these can cause the bottle to expand and contract which may cause the cork to become loose or even pop off. To further protect the wine, it can be placed in a cool box or lidded container with an ice pack to protect it from being exposed to direct sunlight or extreme temperatures.

Finally, unopened bottles of Prosecco should not be stored for more than a year as their quality will begin to decline after this period of time. For optimal enjoyment, Prosecco should be consumed within six months of purchase, when it is at its peak flavor and quality.

Canned and Boxed Prosecco

Canned and boxed Prosecco are becoming increasingly popular as an alternative to traditional bottles of the sparkling Italian wine. While canned and boxed Prosecco may offer convenience and portability, there are some unique considerations to take into account when choosing this type of packaging.


Since canned and boxed Prosecco contain a smaller volume of wine than a bottle, these packages are often intended for immediate consumption. If you do plan on storing your prosecco for an extended period of time, be sure to keep it in a cool, dark place away from direct sunlight. Boxed Prosecco also typically has an expiration date printed on the package, so make sure to check that before purchasing.


The quality of canned and boxed Prosecco may not be as high as its traditional bottled counterpart due to the fact that the packaging process is not as gentle on the wine. Canned and boxed Prosecco is often made with lower-grade grapes which can affect the taste. If you’re looking for higher quality prosecco, it’s best to stick with traditional bottles.


Canned and boxed Prosecco is usually more affordable than traditional bottled versions since they often contain lower-grade grapes or use cheaper packaging materials. However, if you’re looking for a more premium product, you may have to pay a bit more for traditional bottles of prosecco.


When it comes to sustainability, boxed or canned Prosecco is typically more eco-friendly than traditional bottles since it uses less material in its packaging process. Additionally, many brands are now using recyclable materials for their cans or boxes which allows for easier disposal after use.

Properly Storing Open Bottles of Prosecco

When it comes to enjoying a bottle of prosecco, the key is to properly store it once you have opened it. To ensure that you get the most out of your bottle of prosecco, proper storage is essential. Here are some tips on how to store opened bottles of prosecco.

How Long Does Unopened Ice Cream Last in the Freezer

First and foremost, make sure that your bottle of prosecco is kept in a cool and dry place. Prosecco should be stored at temperatures below 50 degrees Fahrenheit (10 degrees Celsius). If you don’t have a temperature-controlled wine cellar, try to find a cool spot in your home or refrigerator to store the bottle.

Once the bottle has been opened, it is important to reseal the cork properly. Make sure that you tightly screw down the cork back into place, so no air can enter the bottle and spoil the contents. If possible, use a vacuum sealer to help keep the cork secure and air tight.

Finally, if your bottle does not have a stopper or sealer on top of it, make sure that you place plastic wrap or aluminum foil over top of the opening before putting it back in storage. This will help keep out any moisture or air from entering into the bottle and spoiling your prosecco.

By following these simple steps when storing open bottles of prosecco, you can ensure that you enjoy every last drop!


Prosecco is a delicious sparkling wine that can last for up to three years when unopened. However, it’s best to keep it in a cool and dark place, as exposure to heat and light can cause it to go bad more quickly. It’s also important to note that the quality and taste of the Prosecco will diminish over time, so it’s best to enjoy an opened bottle within a few days of opening.

Overall, when stored correctly, unopened Prosecco can last for up to three years without any issues. This makes it an excellent choice for those who want to stock up on their favorite sparkling wine or have leftovers from a special occasion that they want to save for later.
