The shelf life of bucks fizz?

Bucks Fizz, a sparkling wine cocktail typically made with champagne and Orange Juice, has a shelf life that depends on its components. Unopened, it can last for about 1-3 years if stored in a cool, dark place. Once opened, it should be consumed within 3-5 days for the best flavor and carbonation. However, if made with fresh juice, it's best consumed immediately or within a day for optimal taste and freshness.
