As a beer-drinker, I whole-heartedly agree. No Bud, Miller, or Schlitz.
There are plenty of good American beers, but they are local. The nearest thing to a wide selling American beer that’s good is Sam Adams.
If I were doing the contract with her, I’d say, fine, your choice. And then maybe afterwards try to introduce her to a few good American beers.
Oddly enough, I can get a 12-pack of Beck, Heineken, or Stella Artois at the supermarket here in Vermont for the same price as a good local beer or Sam Adams, so I sometimes do.
