Opus One is the realized dream of two men: Baron Philippe de Rothschild of Chateau Mouton Rothschild in Bordeaux and Napa Valley vintner Robert Mondavi. Together, they set out to create a single wine dedicated to the pursuit of uncompromising quality.

Winemaker Michael Silacci combines intuition and technical acumen with the dual perspective of viticulturist and winemaker.  From tasting berries to careful sorting and extended aging in new French oak barrels, each stage of the winemaking process is afforded the same meticulous consideration and attention.  After 18 months, the wine is bottled and held an additional 15 months until release on October 1st each year.

The estate vineyards of Opus One, comprised of four parcels, sit in the western portion of the famed Oakville AVA. In the vineyards, hand-harvesting and other traditional approaches are taken wherever they work best. When modern techniques benefit the winegrowing process, they are researched, evaluated and integrated into practice.  At the core is their dedication to nurturing their relationship with the land. Opus One has received organic certification, Fish Friendly Farming Environmental Certification, and is certified as a Napa Green Winery. They are currently in the process of replacing lawns with native, drought-tolerant plants, increasing biodiversity, and implementing regenerative farming practices for healthier soils and vines.
