Here is an American Gruyère, made in Wisconsin that's as good as any produced in France or Switzerland, Roth Käse’s Grand Cru Gruyère Surchoix. I think of Gruyère as "the other Swiss cheese". Swiss-style cheeses tend to be either like Emmentaler (big holes, easily melting, mild flavor) or Gruyère (pungent, firmer, packed with flavor). Together they make a perfect, traditional fondue.
Aged at least nine month's Gruyère Surchoix ("surchoix" means "top choice" in French) is a great tasting cheese. It has a bit of funk to it and I mean that in the best possible way. Some cheeses tickle the roof of your mouth with pungent flavor without being sharp like an aged cheddar. This cheese does that. There are some other flavors I can only describe as tannic, but also in a good way.
It is wonderful with apples or fresh bread, walnuts or arugula salad.
