How to Keep Prosecco Fresh After Opening?

by Kaia

Prosecco, with its effervescence and delightful taste, is a popular choice for celebrations and casual gatherings alike. However, once the cork is popped and the celebration ends, preserving this sparkling wine’s freshness becomes a priority. Learning how to keep Prosecco fresh after opening is crucial to maintain its flavor and effervescence. From proper storage techniques to innovative preservation methods, here’s a comprehensive guide to help you extend the life of your opened Prosecco.


Understanding Prosecco: Factors Affecting Freshness

Before delving into preservation methods, it’s essential to understand why Prosecco loses its freshness after opening. Several factors contribute to its degradation, notably oxidation and loss of carbonation. As soon as the bottle is uncorked, oxygen begins to interact with the wine, causing chemical reactions that can alter its taste and aroma. Moreover, Prosecco’s effervescence, derived from carbon dioxide, gradually dissipates once exposed to air, leading to the loss of its signature bubbles.


Proper Sealing and Storage Techniques

Preserving the effervescence and flavors of Prosecco starts with proper sealing and storage. After opening the bottle, resealing it tightly is crucial to limit its exposure to air. Using a specialized sparkling wine stopper that fits securely in the bottle’s neck helps maintain pressure and prevent excessive oxidation. Alternatively, if a sparkling wine stopper is unavailable, tightly covering the bottle’s opening with plastic wrap and a rubber band can serve as a temporary seal.


Furthermore, storing opened Prosecco properly is essential. Keep the bottle upright in the refrigerator, as this position reduces the surface area exposed to oxygen. Avoid storing it on its side, as this can accelerate oxidation and compromise its taste. Ensure the temperature remains consistent, ideally between 35 to 45 degrees Fahrenheit (1.6 to 7.2 degrees Celsius), to slow down the wine’s aging process and preserve its freshness for an extended period.


Utilizing Vacuum Sealers and Stoppers

Vacuum sealers and stoppers designed specifically for sparkling wines offer an effective way to maintain Prosecco’s freshness after opening. These devices work by removing excess air from the bottle, creating a vacuum that minimizes oxidation and preserves carbonation. Simply place the stopper on the bottle’s opening and pump out the air using the vacuum sealer, creating an airtight seal that helps retain the wine’s quality.

Several options are available, ranging from manual pump-style sealers to electric vacuum pumps designed explicitly for sparkling wines. Investing in a high-quality vacuum sealer tailored for sparkling wines can significantly prolong the freshness of your opened Prosecco.

Avoiding Temperature Fluctuations

Temperature fluctuations can adversely affect the quality of opened Prosecco. Exposure to varying temperatures, especially warmer conditions, accelerates chemical reactions within the wine, leading to faster deterioration. To prevent this, refrain from leaving the bottle outside the refrigerator for extended periods. Additionally, avoid sudden temperature changes, such as moving the bottle from a chilled environment to room temperature, as this can impact the wine’s taste and effervescence.

Maintaining a consistent temperature by storing the Prosecco in the refrigerator and minimizing temperature fluctuations helps preserve its freshness for a longer duration after opening.

Utilizing Inert Gas Sprays

Innovative preservation methods like inert gas sprays offer an effective solution to extend the life of opened Prosecco. These sprays displace the oxygen in the bottle with inert gases like argon or nitrogen, creating a protective layer that prevents oxidation. By spraying a layer of inert gas into the bottle before resealing, you can significantly reduce oxygen exposure and maintain the wine’s freshness.

Inert gas sprays are available in convenient aerosol cans equipped with a thin nozzle to easily inject the gas into the bottle. While this method may require a specific tool, it’s an excellent investment for those seeking advanced preservation techniques for their favorite Prosecco.

Using Preservation Capsules

Preservation capsules, often made of stainless steel, are another innovative solution to preserve opened Prosecco. These capsules are designed to cover the bottle’s opening and create a tight seal, reducing oxygen exposure and retaining carbonation. The airtight seal formed by the preservation capsule helps slow down the wine’s oxidation process, keeping it fresher for longer periods.

To use a preservation capsule, remove the bottle’s cork, place the capsule over the opening, and fasten it securely. This method effectively maintains the wine’s quality and can be beneficial for preserving Prosecco when consumed over multiple occasions.

Re-corking with Fresh Corks

Replacing the original cork with a fresh one after opening can be an effective way to preserve Prosecco. Fresh corks help create a tighter seal, reducing oxygen exposure and preserving the wine’s carbonation and flavor. Specialized sparkling wine corks are available, designed specifically for resealing opened bottles of Prosecco.

To re-cork the bottle, remove the original cork and replace it with a new one designed for sparkling wines. Ensure the cork fits snugly in the bottle’s neck to create an airtight seal. This method can be beneficial for maintaining Prosecco’s freshness, especially when proper stoppers or preservation devices are unavailable.


Enjoying Prosecco doesn’t have to be limited to a single occasion. By employing proper sealing techniques, storage practices, and innovative preservation methods, you can extend the freshness of your opened Prosecco. From vacuum sealers to inert gas sprays and preservation capsules, various options are available to cater to different preferences and needs. Implementing these strategies ensures that each glass of Prosecco maintains its delightful effervescence and flavors, allowing you to savor its taste across multiple celebrations or casual gatherings. Mastering the art of preserving opened Prosecco elevates the drinking experience, ensuring that every sip is as delightful as the first.
