In her mind it was ok for them to use it because she considered New Glarus' usage a sub-title of the beer, so it was used in a different context.
You would think this new brewery could use the same argument, in that it's the name of their brewery and not a beer
Exactly. She shrugs off that the phrase was already being used as part of the name for a New Glarus beer, but gets high and mighty about this. Her rationale that New Glarus was using it "as a descriptor of the style" is pretty weak. It's part of the the New Glarus beer's name. And New Glarus is brewed what, barely 4-5 hours away from Pella? Lame.
