A bottle of opened white wine can generally be kept in the refrigerator for about 3 to 5 days before its quality starts to deteriorate and it loses flavor
- Lighter white wines and sweet whites may last slightly longer, up to 5 to 7 days, due to their higher acidity and sugar content which help preserve them
- Full-bodied whites such as oaked Chardonnay or Muscat tend to oxidize faster and are best consumed within 3 to 5 days after opening
- Sparkling white wines like Champagne or Prosecco should be consumed within 1 to 3 days after opening, ideally sealed with a sparkling wine stopper to maintain their fizz
To maximize freshness, reseal the bottle tightly with the original cork or a stopper and keep it refrigerated immediately after opening. Using a vacuum pump or transferring the wine to a smaller container can also help reduce oxidation
. Unopened white wine, when stored properly in a cool, dark place, can last from 1 to 3 years or longer depending on the quality and type of wine
. In summary, opened white wine is best enjoyed within a few days (3-5 days typically), stored in the fridge with a proper seal to maintain its flavor and freshness.
