A brief history
O'Brien Estate is a family owned and operated winery on 40 acres in the Oak Knoll Appellation of the Napa Valley. Our self-contained estate includes the winery, vineyards, home, and garden.
The wines of O'Brien Estate reflect the soil and micro-climate of the Napa Valley, as well as our selection of rootstock and clone varietals. Traditional winemaking techniques and aging in small French oak barrels allow our wines to express the nuances of our unique terroir, creating a signature of the vineyard in each bottle. Due to our small production and high demand, our hand crafted wines are only available to our members or when visiting with us at the winery.
