But is the beer any good? If it is, then who cares where it originated?* If this stunt promotes craft beer, let it! And if the beer sucks, don't buy it. My guess is that few true "craft" drinkers will be swayed by the pop star status of the creators anyway. I'd be happy to review a bottle. If it's good, I'll say so, and if it sucks, I'll say so.
*within reason, of course. Obviously I'm not looking to buy charles manson's new homebrew blend
