:Hi Marc,  

 I think you are correct, that the 1996 info I was relying on is now out of date. Any help you could provide regarding an authoritative source showing that Gruyère got either EU or French AOC (Or explaining why a Swiss-issued AOC would be binding on France) in 2001 would be much appreciated. (I didn't find that in the English portion of www.gruyere.com; it's possible I missed it.) In the meantime, I'll change the article to indicate your information. —
