Hard liquors last a very long time, especially if the bottle is unopened. Extreme temperature swings and too much light might take a small toll though. The thing to understand is that they certainly do not get any better than the day they were bottled, however. Curiously that is not the case while they are still stored in their original casks and kegs, but as with everything volatile, there is a limit to what good can come of that as well.
