(Wines&Vines) - In 2002, the Terlato family that owns Chimney Rock Winery planted Sauvignon Gris near Rutherford, Calif. The location is through to be one of only two sites growing Sauvignon Gris in Napa County. But that’s not the only thing that distinguishes Chimney Rock’s Elevage Blanc, a white wine that blends the Terlatos’ Sauvignon Gris with Sauvignon Blanc from the same vineyard.
