How many days can keep whiskey open?

Once opened, a bottle of whiskey can be stored for several years. However, the quality of the whiskey may start to decline over time, especially if it is not properly stored. Here are some tips for storing whiskey:

* Keep the bottle in a cool, dark place.

* Avoid exposing the bottle to heat or sunlight.

* Keep the bottle tightly sealed when it is not being used.

* Drink the whiskey within a few years of opening it for best flavor.

If you are not sure whether a bottle of whiskey is still good, take a sip of it. If it tastes off or has a strange odor, it is probably best to discard it.
