How Long Is Whiskey Good For Unopened?
Unopened whiskey can last indefinitely if stored properly. The alcohol content of whiskey acts as a natural preservative, and as long as the bottle is kept in a cool, dark place and is not exposed to heat or sunlight, it should maintain its quality and flavor for many years. However, it’s worth noting that some whiskey enthusiasts argue that certain types of whiskey may actually improve in flavor if allowed to age for several years in an unopened bottle.
