Does sealed champagne have an expiration?

While champagne doesn't technically "expire" in the same way as milk or produce, it does change and age over time. This means that the flavor and quality will change as the champagne ages.

Here's a breakdown:

Non-vintage Champagne:

* Optimal drinking window: 2-5 years from the disgorgement date (the date the yeast sediment is removed).

* After 5 years: The flavors will start to fade and the bubbles might lose their intensity.

* Beyond 10 years: The champagne might become flat and taste more like vinegar.

Vintage Champagne:

* Optimal drinking window: 10-20 years from the vintage year.

* After 20 years: The champagne will start to develop complex, mature flavors and might be better suited for aging.

* Beyond 30 years: It becomes very rare and highly prized, with the potential for exceptional complexity.

Factors that Affect Aging:

* Storage conditions: Proper storage in a cool, dark place with low humidity is crucial for optimal aging.

* Type of Champagne: Some wines, like Blanc de Blancs (made from Chardonnay), tend to age better than others.

* Personal preference: Ultimately, what makes a champagne "good" is subjective. Some people might prefer the youthful exuberance of a younger bottle, while others enjoy the complexity of an aged one.

Bottom Line:

While there's no expiration date on champagne, it's best to enjoy it within its optimal drinking window. If you're looking to age a bottle, be sure to store it properly and be prepared for a significant change in flavor profile.
