Opus One Winery
>Opus One Winery is a winery in Oakville, California, United States. The wine was called napamedoc until 1982 when it was named Opus One. The winery was founded as a joint venture between Baron Philippe de Rothschild of Château Mouton Rothschild and Robert Mondavi to create a single Bordeaux style blend based upon Napa Valley Cabernet Sauvignon. It is located across State Route 29 from the Robert Mondavi Winery. The creation of this winery venture in 1980[1] was big news in the wine industry; de Rothschild's involvement added an air of respectability to the burgeoning Napa wine region. The first vintage, 1979 was released in 1984 at the same time as the 1980 vintage. For a while it was the most expensive Californian wine, and to date still ranks among the most expensive red wines produced in the Napa Valley, with the 2014 vintage retailing for $325 per bottle.[2] In 1989 a new winery was built just down the road, the first vintage from the new winery was from 1991 and was released in 1994.[3]
