Potentially centuries if it is good quality originally.

Alcohol does not expire when it is unopened.
If the bottle is unopened then it can last as long as you want it to, but I personally wouldn't drink it after having for more than 9 months or so.
If you open the bottle, you need to keep it refrigerated and it will last for a month. If it is an unopened bottle it should last for about a year :)
An unopened bottle of Pennsylvania Dutch egg nog will be good for up to seven months. This variety of egg nog contains alcohol.
Alcohol doesn't spoil
It should last indefinitely if kept in a cool, dark place.
It was last for decades if unopened.
I have a bottle of Cointreau that was first opened 16 years ago and it still tastes fine!
Chardonnay is good for about 7 years unopened.
My research showed that an unopened bottle of Pimm's would last for a year or two. Once it is opened, it starts to lose flavor after a week or so.
An unopened bottle of Jack Daniel's can last indefinitely if stored properly, as the high alcohol content acts as a preservative. However, for the best quality, it’s recommended to consume it within 5 to 10 years. Keeping it in a cool, dark place away from direct sunlight can help maintain its flavor and integrity over time.
