Opus One Winery

Opus One is a large wine estate in Oakville that produces Bordeaux-style wines from Cabernet Sauvignon grapes across about 108 acres. The limestone building combines European and Californian design, while rows of vines slope across the landscape and a series of interior spaces guide visitors through the production process.

A French nobleman and an American vintner founded this winery in 1980, bringing together two of the world's leading winemakers. Their partnership marked a turning point in California, where European expertise met American innovation and set new standards for premium wine production.

The building blends European and Californian architectural elements, showing how wine here bridges French tradition and American innovation. Visitors feel this combination in every room and understand why this place became a symbol of transatlantic exchange in winemaking.

Visitors should arrange a visit in advance, as tastings and tours happen by appointment and availability is limited. It helps to set aside time for exploring the building and vineyards, as there are multiple levels to see and the views from the top are worth the effort.

The property sits above geothermal springs that naturally warm the soil and create specific growing conditions for the grapes. This underground heat source subtly contributes to wine quality without being visible to visitors, but its effects can be felt in every glass.
