The shelf life of an unopened bottle of sparkling wine can vary depending on several factors such as the type of sparkling wine, storage conditions, and the production quality of the wine.
In general, most non-vintage sparkling wines (those without a specific year listed on the label) can last up to 2-3 years from the date of production if stored properly in a cool, dark, and dry place with a consistent temperature. Vintage sparkling wines may last longer, up to 5-10 years or more, depending on the quality of the wine and the storage conditions.
It’s important to note that once the bottle is opened, the wine begins to lose its carbonation and flavor, and should be consumed within a few hours or at most, within a day or two.
