Duckhorn Vineyards was founded in 1976 in St. Helena, in the Napa Valley. It was started by Dan and Margaret Duckhorn after Dan, a California native, toured the Bordeaux region of France in the 1970s. In 2007 a private equity firm took a significant ownership interest in Duckhorn, though Dan Duckhorn remains in charge of the estate. The winemaker is Renee Ary. The 229-acre estate is known for its big Cabernet Sauvignons and Merlots. Duckhorn was one of the first California producers to champion Merlot, and its Merlots are still highly regarded although today the estate also makes Sauvignon Blanc, Cabernet France and Semillon. About 75,000 cases are produced annually. Robert M. Parker has written that Duckhorn has “a very positive style that represents a hypothetical blend of the ripeness of Napa allied with the elegance of a top Bordeaux.”
Napa Valley AVA is the most famous winemaking region in the United States and one of the most prestigious in the world. With nearly 43,000 acres of vineyards and more than 300 wineries, it is the heart of fine wine production in the United States. Winemaking started in Napa in 1838 when George C. Yount planted grapes and began producing wine commercially. Other winemaking pioneers followed in the late 19th century, including the founders of Charles Krug, Schramsberg, Inglenook and Beaulieu Vineyards. An infestation of phylloxera, an insect that attacks vine roots, and the onset of Prohibition nearly wiped out the nascent Napa wine industry in the early 20th century. But by the late 1950s and early 1960s Robert Mondavi and other visionaries were producing quality wines easily distinguishable from the mass-produced jug wines made in California’s Central Valley. Napa Valley’s AVA was established in 1983, and today there are 16 sub-appellations within the Napa Valley AVA. Many grapes grow well in Napa’s Mediterranean climate, but the region is best known for Cabernet Sauvignon. Chardonnay is also very successfully cultivated, and about 30% of the AVA’s acreage is planted to white grapes, with the majority of those grapes being Chardonnay,
The Merlot grape is such a deep blue that it is named for the blackbird. It’s an early ripening grape and one of the primary varietals used In Bordeaux. Merlot is also grown in the "International style," which is harvested later to bring out more tannins and body.
