It was a 1973 Stag’s Leap Cabernet Sauvignon that came in first at the now famous 1976 Paris Tasting, the blind tasting of Bordeaux and California Cabernet Sauvignon set up by the English wine merchant Steven Spurrier. The story of the tasting, made into films and books, is now part of the coming-of-age story of Napa Valley wines, and Stag’s Leap will forever hold the title of the little California winery that could. Today the estate is also known as a leader in organic and sustainable winemaking, and it continues to win prestigious international awards for its wines. (Chateau Montelena’s 1973 Chardonnay won the first-place award for white wines at the tasting, meaning that in a blind tasting by French judges California wines won first place in both the red and white wine categories.) Founded in 1972 by Warren and Barbara Winiarski, the winery is in the Stags Leap district of Napa Valley. In 2007 the Winiarski family sold it to a joint venture of Chateau St. Michelle in Washington state and Marchesi Antinori of Italy. It is also partly owned by Altria, the tobacco/food conglomerate.
