Opus One was founded in 1979 as a partnership between Baron Philippe de Rothschild of France and Robert Mondavi of Napa. 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 1985 it became known as America’s first ultra-premium wine. Then in 1988 Opus One became the first ultra-premium California wine to be sold in France, the United Kingdom, Germany and Switzerland. Michael Silacci is the winemaker, and is responsible for both viticulture and winemaking. For more information see http://www.opusonewinery.com.
We will also visit the Robert Mondavi vineyards. The Robert Mondavi winery was built in 1966 and was the first major winery to be built in the Napa Valley after Prohibition. (Prohibition was a United States constitutional amendment that banned the sale, manufacture, and transportation of alcohol; it was passed in 1920 and repealed in 1933.) Robert Mondavi helped introduce to California such fine winemaking techniques as the use of cold fermentation, stainless steel tanks, and French oak barrels. He also popularized Fume Blanc, a name he coined for dry-fermented, barrel-aged Sauvignon Blanc. For more information see http://www.robertmondavi.com
