It really depends on the beer. For the most part, beer does not age well and should be drunk within a year or so of being brewed. There are some stronger stouts that do age well, Bell's Expedition Stout is one such beer, the flavors becoming more complex and rich with time. The standard American Lager does not gain anything by being aged, just more apt to go 'skunky.'
