The act of drinking
a beer that
you did not believe you'd ever tasted before, only to realize at some point while drinking
you have, in fact, had that
beer before. This is not to be confused with drinking
a beer blindly and realizing what it is. It is the act of tasting a beer, with full
knowledge of what kind it is, but with the belief that
it was one you'd never had before.
This happens frequently to beer geeks who either keep poor tasting notes, are forgetful, or who just drink too much beer.
sounds good, let me try that. (sips) Holy beerja vu! I've had this beer
before, it's one of my favorites! Wow, how did I forget about this
