How do you keep can drinks fresh after opening?

Answered by Jesse Garza

As an expert sommelier and brewer, I understand the importance of keeping beverages fresh, especially after they have been opened. When it comes to can drinks, there are a few key steps you can take to ensure they stay carbonated and flavorful.

1. Minimize exposure to air: The main enemy of carbonated beverages is air. As soon as you open a can, the carbonation begins to escape, and the drink starts to go flat. Therefore, it is crucial to minimize the 's exposure to air. One way to do this is by pouring the drink into a glass or another container and immediately sealing it with a lid or cap. This prevents additional air from entering and keeps the carbonation intact.

2. Use airtight containers: If you don't finish the entire can of drink at once, transferring it to an airtight container can help maintain its freshness. A container with a tight-fitting lid will create a seal that prevents air from getting in and preserves the carbonation. Make sure the container is clean and dry before transferring the drink to avoid any contamination.

3. Store in a cool place: Temperature plays a significant role in the shelf life of carbonated beverages. Heat can cause the carbonation to escape more quickly, leading to a flat drink. Therefore, it is best to store opened can drinks in a cool place, such as a refrigerator. The lower temperature helps slow down the carbonation loss, keeping the beverage fresher for a longer period.

4. Avoid shaking or stirring: When you open a can of carbonated drink, it is essential to handle it gently. Avoid shaking or stirring the beverage as this can accelerate the release of carbon dioxide, leading to faster carbonation loss. Instead, gently pour the drink into a glass without agitating it too much.

5. Use specialized preservation tools: There are also specialized tools available in the market designed to keep carbonated beverages fresh after opening. These tools often come in the form of caps or stoppers that fit onto the top of the can, creating a tight seal. They are designed to minimize the contact between the drink and air, helping to preserve carbonation and flavor.

6. Finish the drink within a reasonable time: While taking steps to preserve the freshness of an opened can drink is crucial, it is also essential to consume it within a reasonable time frame. Carbonated drinks, once opened, will gradually lose their carbonation and flavors over time, even with the best preservation methods. Therefore, it is best to enjoy the drink within a few days of opening for the best experience.

In my personal experience, I have found that following these steps has helped me keep can drinks fresh for an extended period. By minimizing exposure to air, using airtight containers, storing in a cool place, avoiding agitation, and consuming within a reasonable time, I have been able to enjoy carbonated beverages as if they were freshly opened. So, next time you open a can drink, remember these tips to savor the carbonation and flavor for as long as possible.
