How Long Will Unopened Whiskey Last?
Unopened whiskey can last indefinitely, as long as it is stored properly in a cool, dark place and away from direct sunlight. Over time, the taste and aroma may change due to exposure to oxygen and evaporation, but it will not spoil or become unsafe to consume. However, it is recommended to consume the whiskey within 1-2 years after opening to experience its full flavor profile.
