O'Neill Vintners & Distillers is a family-owned and operated winery that has grown to become one of the largest varietal wine and brandy producers in California with a reputation for producing high quality wines from the North Coast, Central Coast and Central Valley. Through our extensive vineyards and modern production facilities, O'Neill provides premium winemaking services to the industry as well as our own growing portfolio of national brands (Line 39, Harken, Austerity, Robert Hall etc.), control labels and private labels. Unlike brokers and middlemen, O’Neill Vintners is a primary source winery with comprehensive vertical integration – meaning we make and control all of our own wines from grape to bottle to shelf. We believe this point-of-difference allows us to deliver the quality, consistency and service that customers demand – all at competitive pricing thanks to our economies and efficiencies of scale.
