OK, apparently I got the story wrong. One of the regulars at Snowbowl works for Big Sky Brewing, and he explained to me that the name Troutslayer (and slogan) was licensed, for a time to Bayern (it was previously attached to a beer from the Lange Ales Brewery), and now is licensed to Big Sky. However the name has nothing to do with the beer which happens to bear its name at a given time (I think this is stupid). That said, I hear that Big Sky's Troutslayer sucks. Dancing trout is still as yummy as when it was labled Troutslayer, but pales in comparison to all but one of their seasonals (the summer hefe, which is quite good too).
