I forget why I looked up bock, as in bock beer ‘strong dark German beer,’ but I was startled to see in the Wikipedia article this origin story:
The style known now as bock was a dark, malty, lightly hopped ale first brewed in the 14th century by German brewers in the Hanseatic town of Einbeck. The style from Einbeck was later adopted by Munich brewers in the 17th century and adapted to the new lager style of brewing. Due to their Bavarian accent, citizens of Munich pronounced “Einbeck” as “ein Bock” (“a billy goat”), and thus the beer became known as “bock”. To this day, as a visual pun, a goat often appears on bock labels.
Is that true? I mean, the OED says it’s “< Einbeck, Eimbeck, a town in Lower Saxony, Germany,” so I guess the ultimate origin is correct, but is it true about the Munich accent?
