About the Winery
William & Mary is a small family label built on a family ranch. Mary was born and raised on Shifflett Ranch, and she remembers being embarrassed to say where she was from, since many people then linked Napa with the state hospital. William is a fellow Californian from San Diego. They met through friends over drinks, and a move north, a wedding and a family followed.
The Shifflett family bought the ranch at the end of Darms Lane, just south of Yountville in the Oak Knoll District, in the early 1940s. Over the decades it has run horses, cattle and olives, but grapes now take center stage, and three generations on it is still home to the extended family. The current releases are a 2022 Cabernet Sauvignon and a 2022 Proprietary Red, both from Shifflett Ranch.
The wines are offered by allocation to the mailing list. William & Mary has no tasting room and publishes no visiting program, so it does not receive visitors. The day below stays close to the ranch, with private tastings between Yountville and the city of Napa, including a cave visit and an afternoon in the middle of a working vineyard.
