Lucien Sionneau, winemaker of Chateau Mouton Rothschild, and Timothy Mondavi, son of Robert Mondavi, produced the first wine since their cooperation in 1979. The following year, they formally announced the establishment of a joint venture.

In the first Napa Valley wine auction in 1981, a single case of wine produced by this joint venture sold for $24,-the highest price of wine produced in California. In 1982, Robert Mondavi and Baron Philippe de Rothschild began to design trademarks. They agreed to choose a word from Latin as the name of the joint venture, so that anyone who speaks English or French can understand it. Baron Philip announced that his choice was "Opus", the composer's first masterpiece, in music. Two days later, he added another phrase "Opus One".

1979 and 198 standard wines were launched as the first products of Opus One in 1984. Opus One became famous as the first super-premium wine in the United States, and established a wine classification with a price of more than $5.

After Lucian Sinu retired in p>1985, Patrick Léon joined Mutong Winery as a winemaker, and Timothy Mondavi became the winemaker of Opus One.

Three years later, Baron Philippe died in France at the age of 85. Baroness Philipping took over the family wine business. In the same year, Opus One exported some of its 1985 products to France, Britain, Germany and Switzerland-the first super-premium California wine exported to these places. Opus One received a steady stream of international orders. In 1999, it celebrated its 2th anniversary, and held vertical wine tasting and celebration dinners in Oakville, new york, Paris and London. In 21, Opus One released the 2th vintage-The 1998, and held celebrations in Tokyo and Hong Kong.

in p>24, the company's board of directors appointed David Pearson as the CEO, as the first manager who was solely responsible for Opus One. Subsequently, Michael Silacci was appointed as the winemaker, and he was the first person in charge of grape cultivation and winemaking.

In p>25, Constellation Brands, Inc acquired Robert Mondavi and held 5% shares in Opus One. Baroness Philippe and Robert Sands, President and Chief Operating Officer of Constellation Brand Company, announced that Opus One is jointly controlled by Baroness Philippe rothschild Co., Ltd. and Constellation Brand Company.
