But tap handles aren't labeled with contract info as far as I have seen (not CA or TX). I'm sure the keg collar is labeled, but how would a person at the bar know. I've never seen "Lone Star, brewed locally by Miller in Fort Worth, owned by Russians" on a menu or tap handle.
It doesn't matter if the seller busted his back making it or not. Do you think Jim Koch gets down and dirty on thousand barrel batches? Hell no, he has employees. In my opinion, contracts can be seen the same way.
Chimay, Westy, duvel and the like are not going away anytime soon. They shouldn't be so scared.
