The genesis of great wines is great vineyards. Our Oso Vineyard, located between Sugarloaf Mountain and Howell Mountain in the great Napa Valley, is a truly special labor of love. In 2004, our family planted this spot with cuttings from one of the best known root stocks of Sauvignon Blanc with origins tracing to the esteemed Château d'Yquemand which first made its way to California via Charles Wetmore, renowned wine pioneer of the 1880s. Ten years after planting and using the same trellising methods from the 19th century, we made our first vintage of Sauvignon Blanc. Since then, our Heritage Block has delivered beautiful Sauvignon Blanc, vintage after vintage.
