Viader Vineyards is on the slopes of Howell Mountain. It was founded in 1986 by Delia Viader, who was born in Argentina and educated in Europe before earning graduate degrees in the U.S. The estate’s 23-acre vineyard is planted to Cabernet Sauvignon, Cabernet Franc, Petit Verdot and Syrah. Viader is known for its Bordeaux-style blends. Viader typically receives complimentary reviews and scores in the 90s. California Wine Writer James Suckling has noted that at Viader “quality is very high; the wine is distinctive, complex and elegant.”
