Sparkling Wine: Sparkling wines generally last 1-3 days after opening. Their bubbles quickly dissipate, even if stored with a sparkling wine stopper, which helps prolong their freshness slightly.
Light White, Rosé, and Sweet Wines: These types of wines can last 5-7 days in the fridge with a cork. Over time, the wine will oxidize, leading to subtle changes in taste.
Full-Bodied Whites: Full-bodied white wines, such as Chardonnay, last about 3-5 days in the fridge with a cork. Their structure and flavors start to degrade more quickly than lighter wines.
Red Wines: Red wines can generally last 3-5 days after opening when stored in a cool, dark place and sealed with a cork. Refrigeration can extend this to up to a week, though they should be brought to room temperature before drinking.
Fortified Wines: Fortified wines like Port, Sherry, and Madeira last significantly longer after opening, typically up to 28 days, due to their higher alcohol content which acts as a preservative.
Storage Conditions: The longevity of opened wine greatly depends on storage conditions. Keeping the bottle tightly sealed with a cork and storing it upright to minimize exposure to oxygen can extend the wine's shelf life.
Signs of Spoilage: Indicators that the wine has gone bad include off smells (like vinegar or wet cardboard), a significant change in color, and a sour or flat taste. If any of these are present, it’s best to discard the wine.
