Recently while visiting my father I stumbled across some really old beers he had stashed below his bar. Two in particular I have the urge to crack open and try. One is a St. Pauli Girl imported dark beer. It doesn't have any date on it but may be as old as the 70's. The other one is a Dark Henninger Bier, imported from Germany which also could be that old. He has about six others or so but I figured the dark beers would have the best chance of aging well. My only other hope is the fact that it has been in a completely dark bar where virtually no light has touched it. Dare I crack open that old of a beer or simply hang on to the full beer bottles as kind of a be at little find. My personal philosophy is if you have beer, mine-as-well drink it. Can someone please help me out. Cheers!
