How long will an unopened bottle of whiskey last?

[00pumpkin]

I’ve stockpiled a few bottles (limited supply) that I wish to save for years down the road. But I got to thinking the other day about the possibility of the whiskey going bad? Can this happen?

My wife and I opened a bottle of champagne that was dated 1985 (purchased 4-5 years later I assume) at our wedding and it tasted perfect. I assume whiskey could last even longer.
