Founded in 1990 by Betty O'Shaughnessy, this Angwin estate spans three prestigious Napa appellations—Oakville, Howell Mountain, and Mt. Veeder—crafting Cabernet Sauvignon and Bordeaux varietals with care. Under winemakers Sean Capiaux, Aaron Elam, and Mara Couch Fitzgerald, O'Shaugnessy focuses on quality from vineyard to glass, including fruit from Betty's vineyard.
