O'Brien Estate is a family owned and operated estate winery located in the Oak Knoll Appellation of the Napa Valley. Set on 40 acres, it is a self-contained estate.  Located on the property is the winery, vineyard, home and gardens. 

Our artisan, handcrafted wines are only sold at O'Brien Estate - they are not available at retail stores anywhere in the world due to the limited quantity we make each year and the amount of wine allocated to our members.

Our wines reflect the soil, air, and sunlight of Napa Valley. Traditional winemaking techniques and aging in small French oak barrels allows our wine 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!
