It was Mondavi who proved to the rest of California that great wines could be made from Sauvignon. Called Fume Blanc by Mondavi, whether it is his regular, fruity, melony, medium-bodied Fume, or the more oaky, honeyed, lavishly rich Reserve, they are wines to search out. Super-flexible with food, they are at least very good. The 1991 Reserve is a beauty - rich, full, and vibrant. Drink it over the next year.
