The California winery is located in the south of San Francisco in the Gavilan Mountains east of the Salinas Valley in Monterey County
. Its origins date back to 1890, when the Frenchman Charles L. Tamm first planted a vineyard here. In 1964 the property was acquired by the Californian viticulture pioneer Richard H. Graff (1937-1998). Together with the famous celebrity chef Julia Child (1912-2004) and Robert Mondavi
(1913-2008) he founded the "American Institute of Food and Wine". Graff planted new vineyards and studied new winegrowing techniques. He was one of the first in California to experiment with malolactic fermentation for white wines, as well as ageing with imported French barriques. His aim was to produce top wines from Chardonnay and Pinot Noir, following the example of great Burgundies. At the legendary Paris Wine Tasting
in 1976, the Chardonnay took third place in 1974, leaving behind renowned wines from Burgundy and California. Together with partner Phillip Woodward, the rapidly expanding Chalone Wine Group
was founded in 1971. After Graff's death in a plane crash, Dan Karlsen became the responsible cellar master. The Chalone Wine Group was acquired by the giant beverage company Diageo
in 2005. The vineyards of Chalone Vineyard cover 63 hectares, which is the entire AVA area of Chalone. Due to low rainfall, artificial irrigation
is necessary. There are wines from the red wine varieties Cabernet Sauvignon, Merlot, Pinot Noir and Syrah, and the white wine varieties Chardonnay, Chenin Blanc, Pinot Blanc, Sauvignon Blanc and Viognier.
