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, vineyard, home and gardens. Watch a virtual tour.
Our artisan, handcrafted wines are only available at O'Brien Estate and to our members. Our wines are not available at retail stores anywhere in the world, since our limited production is completely allocated to our members.
Our wines 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 the bottle.
We look forward to meeting you in the Napa Valley!
