How long does an unopened bottle of non-vintage champagne last? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of unopened champagne, store in a cool, dark cupboard, away from direct heat or sunlight.
Champagne is non-vintage if it has been made using grapes from two or more years' harvests; it will not be specifically dated by year on the label.
To maximize the shelf life of unopened champagne, place the bottle on its side rather than standing it upright - this will keep the cork moist and airtight.
How long does unopened non-vintage champagne last? Most non-vintage champagnes are at their best quality within 3 to 5 years of production, although they will stay safe indefinitely if properly stored.
Should an unopened bottle of champagne be stored in the refrigerator? For best quality, unopened champagne should not be refrigerated until 1-2 days before drinking.
How to tell if champagne has gone bad? The best way is to smell and look at the champagne: if champagne develops an off odor, flavor or appearance, it should be discarded for quality purposes.
