Over the past year i've collected a handfull of different scotches. Some i like enough (and are moderately priced enough) to drink nightly, others i would like to save for special occasions.

The problem is that when i get a new bottle, i can't help but open and try it--This has resulted in having about a dozen different bottles of opened spirits. Macallan 12yr for example, i drink regularly and am not worried about. However, i also have some older (and more expensive) bottles that i don't want to drink regularly. A Highland Park 25yr for example might only be drank on special occasions such as a new yrs toast....

The question then follows--- how long will an opened bottle of Scotch stay good? Does whisky "go bad" ?

Thanks guys,
