Opus One: A California First Growth with Bordeaux Elegance
Opus One, a world-renowned wine, was born from the visionary collaboration of two iconic figures in the wine world: Baron Philippe de Rothschild, the legendary owner of Chateau Mouton Rothschild in Bordeaux, and Robert Mondavi, a pioneer of Napa Valley winemaking. In the 1970s, these two giants merged their expertise and ambition to create a wine that would rival Bordeaux’s First Growths, while capturing the unique essence of California's Napa Valley. This monumental collaboration marked the birth of Opus One, a Bordeaux-style Grand Vin that has since risen to global prominence, standing among the finest wines in the world.
The Origins of Opus One: A Meeting of Two Worlds
The idea for Opus One came about in the early 1970s when Baron Philippe de Rothschild and Robert Mondavi began to explore the possibility of creating a world-class wine in Napa Valley, combining the traditions of Bordeaux with the potential of the New World. By 1979, their dream took shape with the first vintage of Opus One, made from the best parcels of Mondavi’s estate, including the 35-acre Q Block of the prestigious To-Kalon vineyard. The very first release of Opus One in 1984, priced at $50 per bottle, made it the most expensive wine from California at the time, drawing unprecedented international attention to Napa Valley and placing it on the map of global fine wines.
This early partnership between Rothschild and Mondavi brought together two very different winemaking styles. Lucien Sionneau, winemaker at Château Mouton Rothschild, favored structure and a more traditional approach, while Robert Mondavi’s son, Tim Mondavi, preferred a rich, well-rounded style with an openness to experimentation. The result was a harmonious blend that defined Opus One—a wine that reflects both the elegance of Bordeaux and the bold character of Napa Valley.
A Unique Terroir: Oakville AVA, Napa Valley
Opus One’s exceptional quality stems from the unique terroir of the Oakville AVA, an Eden for Cabernet Sauvignon in the heart of Napa Valley. The wine is produced from four different parcels of land: two famous plots in the 40-hectare To-Kalon vineyard and the River and Ballestra Parcels, which surround the Opus One winery. Together, these plots create a total of 28 hectares. These vineyards benefit from the perfect blend of soil, climate, and elevation, contributing to the wine’s complexity and character.
While the blend varies slightly from vintage to vintage, Opus One is typically dominated by Cabernet Sauvignon, with additional contributions from Cabernet Franc, Merlot, and Malbec—varietals that are classic to Bordeaux’s Left Bank. The wine undergoes vinification in stainless steel tanks before being aged in French oak barrels for 18 months. After barrel aging, it spends another 15 months maturing in the bottle before being released each year on October 1st. This careful process results in a wine that expresses the purity of its terroir, with a refined balance of power and elegance.
A New Era and Continued Excellence
Opus One was originally crafted at the Robert Mondavi Winery, but by 1991, production had moved to a state-of-the-art facility in Oakville, designed specifically to accommodate the growing demand for the wine. With modern winemaking techniques and improvements in vintage quality following a five-year drought, the 1990s marked a turning point for Opus One. The wine's quality reached new heights, further establishing its reputation on the global stage.
In 2000, Michael Silacci, a winemaker from Stag’s Leap Wine Cellars, was brought on as head winemaker. Working alongside Philippe Dhalluin, the new winemaker at Mouton Rothschild, Silacci introduced diverse vine clones, which brought even greater complexity to the wine. Their efforts reinforced Opus One’s signature style of restraint and elegance, setting it apart from many of the riper, more opulent Napa Valley wines.
Opus One continued to evolve under the management of both families until Robert Mondavi sold his namesake winery to Constellation Brands in 2004, along with his 50% share in Opus One. Despite this transition, the Rothschild family remained deeply involved in the project, ensuring the wine's continued legacy of excellence.
Winemaking at Opus One: Tradition Meets Innovation
Today, Opus One is crafted from its four iconic vineyard parcels, where traditional viticulture practices like manual harvest are still employed. However, the winery also incorporates modern techniques when they enhance the quality of the wine, striking a perfect balance between innovation and tradition. Each wine plot is vinified separately in stainless steel tanks before being aged in new French oak barrels for about 18 months. Afterward, the wine is further refined by aging in the bottle for another 15 months before being released to the market.
The result is a wine that is designed to express the unique character of its terroir and vintage, without unnecessary intervention from the winemaker. In contrast to the often jammy, rich wines typically associated with Napa Valley, Opus One offers a sophisticated elegance and structure, reminiscent of Bordeaux’s finest estates. As approximately one-third of Opus One’s production is exported, the wine is crafted with a global audience in mind, appealing to palates beyond just the American market.
Overture: A Second Wine with Grandeur
In addition to its flagship wine, Opus One began producing a second label in 1993 called Overture. This non-vintage blend is made from the same five varietals as Opus One—Cabernet Sauvignon, Cabernet Franc, Merlot, Malbec, and Petit Verdot—but offers a more accessible price point while still maintaining the elegance and complexity of the estate's main wine.
A Legacy of Two Visionaries
Even after Robert Mondavi’s passing and the sale of his winery, Opus One continues to be a symbol of the visionary partnership between Baron Philippe de Rothschild and Robert Mondavi. Today, the wine is regarded as one of the finest in the world, embodying the best of both the Old World and the New World. The blue label on every bottle tells the story of this iconic collaboration—a merger of dynasties that gave birth to one of the most prestigious and highly sought-after wines globally.
