What if I told you there's an entire category of beers whose name is, essentially, a long-running dad joke from the 1600s? Would you be at all surprised that I would want to cover it for Doin’ Beers, the only monthly Minnesota beer column full of bad jokes and decidedly mid tasting notes? No, I don’t think you would. You know better, dear reader, than to underestimate my affinity for dad jokes. The style now known as “bock” was first brewed in a nice little German town called Einbeck in the 1300s.
