9 yrs old whiskey unopened bottle can be used now?

Yes, an unopened bottle of 9-year-old whiskey can be consumed now. Whiskey, once bottled and sealed, stops aging. As a result, the whiskey in the bottle is at its peak quality and will not improve with further aging.

However, it's important to consider that certain environmental factors, such as extreme temperatures or direct sunlight, can affect the quality of whiskey over time. To ensure the best taste and experience, it's recommended to store the whiskey in a cool, dry, and dark place.

If the whiskey has been properly stored and is unopened, it should be safe to consume and will still retain its original flavors and aromas.
