Stag's Leap Wine Cellars is a winery founded by Warren Winiarski in 1970 and based in the Stags Leap District of Napa Valley, California.

The Paris Wine Tasting of 1976, also known as the Judgment of Paris, was a wine competition organized in Paris on 24 May 1976 by Steven Spurrier, a British wine merchant, and his colleague, Patricia Gallagher, in which French oenophiles participated in two blind tasting comparisons: one of top-quality Chardonnays and another of red wines. A Napa County wine rated best in each category, which caused surprise as France was generally regarded as being the foremost producer of the world's best wines. By the early 1970s, the quality of some California wines was outstanding but few took notice as the market favored French brands. Spurrier sold predominately French wine and believed the California wines would not win.
