PBR

Duh!

But if you insist:  
American Style Premium Lager
Pabst Blue Ribbon is a premium lager brew crafted with a hefty infusion of 6-row barley in its ingredient package, a carefully balanced carbohydrate profile from corn syrup, and a unique combination of Pacific domestic hops blended with an imported Yugoslavian variety.  Fermented with a pure culture of yeast and aged at high gravity, PBR is cellared and finished to the smooth, robust likeness of a fine Pilsner.
