I bought a fresh 4 pack of O.K. Beer which is considered a European Lager, coming in at 5.6% ABV. I enjoy this beer and frequently purchase it. The last 4 pack had an old date on the bottom of the cans. About six months old. However, when I compared it to a relatively fresh can, there was zero difference in taste. As for Pilsners and IPA's, I try to purchase them less than 8 weeks of canning or bottling. Do lagers basically hold their own when it comes to age?
