How Long Can You Keep An Unopened Bottle Of Champagne?
An unopened bottle of champagne can last for several years in a cool and dark place, such as a wine cellar. Generally, champagne can be stored for up to 3-5 years without any significant changes in taste or quality. However, some high-quality champagnes can age well for a decade or even more, depending on the producer and vintage. It is vital to make sure that the cork remains moist and tight to prevent the oxidation of the wine.
