You have an unopened bottle of 27 yeqr old whiskey is it still good?

Generally, yes. Whiskey does not expire in the same way that food or beverages with significantly shorter shelf lives do. The high alcohol content of whiskey acts as a preservative, preventing the growth of bacteria and other microorganisms that can cause spoilage.

Once opened, whiskey can lose its flavors over time due to oxidation, but this process is very slow and subtle, and it will take years for the quality to deteriorate significantly. However, an unopened bottle of whiskey can maintain its flavors and quality for decades or even centuries.

Factors such as storage conditions and the quality of the whiskey itself can also affect its longevity. Storing the whiskey in a cool, dark place, away from direct sunlight and extreme temperatures, will help to preserve its flavor and quality for longer.

If you are concerned about the quality of your 27-year-old whiskey, you can always open the bottle and taste it. If it tastes and smells good, it is safe to consume.
