The longevity of an opened bottle of wine depends on several factors, including the type of wine, storage conditions, and preservation methods. Here’s a general guide to how long different types of wine can last once opened:

1. Red Wine: Opened red wine can last 3 to 5 days if stored in a cool, dark place and re-corked or sealed with a vacuum stopper to minimize oxygen exposure.

2. White Wine and Rosé: These wines typically last 3 to 5 days when stored in the refrigerator. It's important to re-seal the bottle to reduce air exposure.

3. Sparkling Wine: Opened sparkling wine, such as Champagne and Prosecco, can last 1 to 3 days. Using a special sparkling wine stopper can help retain the bubbles longer.

4. Fortified Wine: Fortified wines like Port, Sherry, and Madeira have a longer shelf life due to their higher alcohol content. They can last 1 to 3 weeks if kept in a cool, dark place.

5. Natural Wines or Wines Without Added Sulfites: These wines tend to have a shorter shelf life, generally lasting 1 to 3 days after opening.

Tips for Preserving Opened Wine:

• Refrigeration: Storing wine in the refrigerator helps slow down the oxidation process.
• Vacuum Pump: Using a vacuum pump to remove air from the bottle can extend the wine’s lifespan.
• Airtight Stopper: A good airtight stopper can minimize oxygen exposure.
• Proper Storage: Keeping the wine in a cool, dark place helps preserve its flavor and aroma.

While these guidelines are generally accurate, the taste and quality of the wine may begin to deteriorate within these time frames. The key is to minimize oxygen exposure and maintain the wine at an appropriate temperature.
