Actually ... no, not unless you buy it by the cask for self-maturing. Whisky matures in wood barrels, but not in glass flasks. As opposed to a bottle of wine (that matures in the bottle), nothing really changes in a bottle of spirits, except for the incredible slow processes of evaporation through the cork.



Yup, that's right. If the sealant is unbroken, you're probably talking about shelf life of centuries, or at least the majority of one century.


But I'm sorry to say that in most opened and partly drunk bottles the flavor will degrade over a few years... which kind of bogs me as I love single malts, but rarely drink enough of it to keep my collection from aging.
