Is it safe to drink Champagne even if it is more than 20 years old?
Yes it is still very safe to drink. Champagne and sparkling wines that are unopened will mature and age and will remain safe to drink for decades, perhaps even a century in some rare cases. Some types and vintages age better than others, but in general, even basic champagnes can age somewhat over time, provided they are stored properly. Depending on whether or not this is a vintage or non vintage Moët, as well as how it was stored, this particular bottle could have improved in quality or have suffered some serious problems. Factors like the temperatures that bottle was exposed to, as well as the amount of light can determine whether or not the champagne aged properly. Even if the bottle is oxidized or has lost some of it’s sparkle, it’s still safe to drink. However, it might not taste as good as it might have if it had been stored properly.
