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.

  • Mark Davis

    Mark Davis grew up in Maryland, just outside of Washington, D.C. (not exactly wine country). After graduating from the University of Maryland with a degree in chemical engineering, his love of fermentation science (and boredom at his government job) brought him to California to see what winemaking was really like, outside of a small home-based hobby he had dabbled with.

    Mark quickly fell in love with the whole winemaking process: from tasting grapes to check for ripeness, to pumping over tanks, to shoveling out grape skins, and generally getting your hands dirty making great wine. After his first vintage, Mark applied to the world-renowned UC Davis viticulture and enology program. He was accepted and spent two years learning as much as possible about everything having to do with growing grapes and making wine. Mark graduated with high honors in 2010 and also received the honorary department citation for outstanding achievement in viticulture and enology.

    After several vintages across northern California as well as in Australia and South Africa, Mark eventually was given the opportunity to start his own label and in 2012 Cobden Wini Wines was born. As well as handling every aspect for the Cobden Wini label, Mark is also the winemaker at O’Brien Estate Winery in Napa. Mark continues to learn every day and strives to make the best wines possible while still making sure to have fun every step along the way.
