About William Hill Estate Winery
William "Bill" Hill, a Stanford-educated Oklahoma native who caught the wine bug traveling through Burgundy, moved to Napa Valley in 1974 and founded his namesake winery in 1978 on 200 acres of the Silverado Bench. In a landmark 1983 blind tasting at San Francisco's Mark Hopkins Hotel, William Hill's 1979 and 1980 wines outscored First Growth Bordeaux estates including Château Mouton Rothschild, Château Latour, and Château Lafite-Rothschild.
Hill sold the winery in 1992, and it has since changed hands several times; Gallo has owned the property since 2007. As of June 2024, the William Hill tasting room has permanently closed, though production of William Hill wines continues; Bill Hill himself still owns nearby Broken Rock Vineyard, supplying fruit to his family's Prime Solum label.
