One reason I never miss a chance to visit Jean Dirler and his family is that the Dirler-Cadé estate in Bergholtz makes outstanding wines from several different Alsace varieties. Its Sylvaner, a grape often treated as an afterthought in Alsatian wine-production circles, is especially noteworthy. I do not feel that I am exaggerating when I describe it as a world-class wine, and the fact that it ages extremely well is an added bonus.
