[QUOTE=greggwiggins;9794528But cellaring is a bad idea for beers like pale ales or IPAs because one of the things that happens as a beer ages is that the flavor of the hops mellow and become less prominent.[/QUOTE]

It's interesting that the IPA style was developed specifically to prolong the life of the beer on long ocean voyages (e.g., from England to India, hence India Pale Ale). Since we now have refrigeration and faster modes of transportation than sailing vessels, the IPA style is now appreciated for its own flavor, rather than its ability to resist spoilage. Perhaps the sailors of old thought the IPA tasted best at the end of the voyage, when the hops had mellowed and it tasted more like a "normal" ale to them.
