what happens after you age it?
some beers are meant to be consumed as soon as possible: these are your mainstream beers (anywhere from mass produced bud light to your more corporate "microbrews" such as stella artois, etc), as well as any pale ale's, IPAs, wheat beers, lagers. pilsners, etc.
other beers are actually meant to be consumed later, and can be aged in a similar fashion to wine. these are typically darker, bigger beers (barleywines, imperial stouts, belgian strong ales, belgian quads, any bourbon/barrel-aged ales, etc.). when stored properly the beer actually becomes more and more complex over time.
so for example:
- if you come across bottles of pliney the elder, stone ruination, etc. you want to buy and drink immediately (the closer to the "bottled on" date the better).
whereas
- if you come across FSW parobala, the bruery's black tuesday, or alesmith's decadence you want to buy 2 of each immediately. one should be drunken soon, while the other should be stored for at least 12 months before consumed.
