The Story

Château Mouton Rothschild winemaker Lucien Sionneau and Robert Mondavi’s son Timothy made the partnership’s first vintage at the Robert Mondavi Winery in 1979. The following year the partners officially announced their joint venture.

In 1981 a single case of the joint venture wine sold for $24,000 at the first Napa Valley Wine Auction – the highest price ever paid for a California wine. In 1982 Robert Mondavi and Baron Philippe de Rothschild began label design. The partners agreed to choose a name of Latin origin for the joint venture, allowing for easy recognition in both English and French. Baron Philippe announced his choice, “Opus,” a musical expression denoting the first masterwork of a composer. Two days later he proposed an additional word: “Opus One”.

The 1979 and 1980 vintages were simultaneously unveiled in 1984 as Opus One’s first release. Opus One then became known as America’s first ultra-premium wine, establishing a category of wine priced by the bottle at $50 and above.

Following Lucien Sionneau’s retirement in 1985, Patrick Léon joined Château Mouton Rothschild as winemaker and Timothy Mondavi as co-winemaker of Opus One.

Three years later, Baron Philippe de Rothschild died in France at the age of 85; and Baroness Philippine de Rothschild took the reins of the family wine business. This same year Opus One exported a share of its 1985 vintage – and became the first ultra-premium California wine to be sold in France, the United Kingdom, Germany and Switzerland. International demand for the wine continued, and in 1999 Opus One celebrated its 20th anniversary by holding vertical tastings and gala dinners in Oakville, New York, Paris and London. In 2001 the release of its 20th vintage – the 1998 – was met with gala events in Tokyo and Hong Kong.

The winery’s board of directors appointed David Pearson CEO in 2004, the first person singly responsible for Opus One. Michael Silacci was thereafter named winemaker, the first to assume full responsibility for viticulture and winemaking.

Constellation Brands, Inc. purchased Robert Mondavi Corporation and assumed 50% ownership of Opus One in 2005. Baroness Philippine de Rothschild and then Constellation Brands President and COO Robert Sands announced the Opus One Accord between Baron Philippe de Rothschild, S.A. and Constellation Brands, Inc. Opus One assumed operating independence in three key areas: vineyard management, domestic and international sales, and administration.
