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, our founders set out to create a single wine dedicated to the pursuit of uncompromising quality. This singular mission shapes every vintage, today and for generations to come.
The estate vineyards of Opus One, comprised of 4 parcels, sit in the western portion of the famed Oakville AVA. Two parcels, totaling 100 acres, are within the renowned To Kalon Vineyard. These are complemented by the combined 70 acres of the Ballestra and River parcels, which envelop the winery. 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
