Ah, Pabst. Or, depending on when you first encountered it, PBR. Well, I guess it's always been PBR but, when I was in my undergrad, the music and art kids who drank it prominently called it Pabst.
Pabst Blue Ribbon is a staple. I think I've seen it in every bar I've ever been in. Every gas station I've ever visited has has it. It's (anecdotally) as ingrained in American beer and brewing culture as AB InBev, and Miller, and Molson Coors, yet (again, anecdotally) thought of as being on a lower tier. And I've never really gotten that (well, okay, maybe it's deservedly lower than many of Miller and Molson Coors' beers, but it's definitely at least on-par with any Budweiser product).
Today, I'll drink a can and give you my thoughts.
