We're not talking about your average beer with a mere shelf life of 3-6 months, tops -- before quality begins to degrade. We're talking about beers that beg for maturation and strict storage like vintage beers, barleywines, imperial stouts, Belgian strong ales, lambics, old ales and so on. Ideally, any type of beer that can be laid-down for a year or two, or even more, in order to build a slew of complexities and thus further its character in a positive way." at Beeradvocate
