If it has refermentation in the bottle yes, otherwise no. They sell beers that have aged 10 - 20 years, just like wines, but not with the pilseners, but with the stronger beers. With the refermantation, some beers almost taste like wines after a few years. It is said that if you age a beer with refermentation on the bottle, the alcohol level goes up 1% every yearDoes beer get better with age? I have a six pack in my Refrigerator that's been there for 6-7 years now.
