Vanessa Wong combines the best of new- and old-world winemaking. She followed up her 1992 U.C. Davis degree in viticulture and enology with studies at Bordeaux’s Institut d’Oenologie and stints at Château Lafite Rothschild and Burgundy’s small Domaine Jean Gros. At Peay Vineyard on the Sonoma coast, Wong, 41, makes technically precise yet personal wines with the artisan sensibility she acquired in France. “The whole family is involved,” she says of Jean Gros. “They eat and breathe this existence.”
