Daniel Baron is an American winemaker. He is best known for his work with the Duncan family-owned Silver Oak Cellars and Twomey Cellars, and was Director of Winemaking for both. After his retirement in 2017, he launched Complant Wine with his son, Sam Baron, to produce small production, artisanal, single vineyard wines. Originally a field worker for John Rolleri at Chateau Montelena, he gained experience in the Bordeaux region of France and was mentored by the likes of grape geneticist Professor Harold Olmo, and winemakers Jean-Claude Berrouet and Justin Meyer. He became general manager of Christian Moueix's Dominus Estate in the 1980s. He became winemaker for Silver Oak, an exclusive Cabernet Sauvignon producer, in 1994, and was trained by Justin Meyer to follow in his footsteps as Silver Oak's winemaker before Meyer’s retirement in 2001. In 1999, Baron was instrumental in persuading the Duncans to establish Twomey to pursue Merlot, Pinot noir, and Sauvignon blanc after discovering high quality Merlot grapes on Silver Oak’s Soda Canyon Ranch Vineyard. He has served on boards such as the American Society of Enology and Viticulture and the Napa Valley Wine Technical Group.
