After opening a bottle of white wine, its freshness and flavor will gradually decline over time, even when stored properly in the refrigerator. Typically, you can expect an opened bottle of white wine to remain enjoyable for about 3 to 5 days. However, this duration can vary depending on multiple factors, including the type of white wine, the storage method, and how much air exposure the wine has experienced.
Lighter white wines such as Sauvignon Blanc and Pinot Grigio tend to lose their vibrant qualities sooner, often within 2 to 3 days, whereas fuller-bodied varieties like Chardonnay or Viognier may retain their desirable characteristics for up to 5 days or slightly more.
To maximize freshness, always reseal the bottle tightly with its original cork or a specialized wine stopper immediately after pouring. Store the bottle upright in the refrigerator to minimize surface contact with oxygen, which helps slow down oxidation and preserves the wine’s integrity for a longer period.
