Is 10 year old Kahlua too old to drink?

Kahlua, like other liqueurs, does not spoil or go bad in the same way that perishable products do, especially if it has been stored properly in a cool, dark place and the seal has remained intact. While a 10-year-old bottle may not taste as fresh as a newer one, it is generally safe to drink. However, the flavor may have changed over time, so it's best to check for any off odors or unusual appearance before consuming. Always drink responsibly and in moderation.
