On May 24, 1976, a British wine merchant named Steven Spurrier organized a blind tasting in Paris that would reshape the global wine industry forever. The event was conceived as a celebration of the American Bicentennial - a friendly comparison between the finest wines of France and a selection of upstart California bottles that few in Europe had ever tasted. Spurrier invited eleven French judges, all respected figures in the French wine establishment. Only one journalist attended: George M. Taber from Time magazine. No one expected the results that followed.

The tasting pitted four white Burgundies against six California Chardonnays, and four red Bordeaux against six California Cabernet Sauvignons. The judges swirled, sniffed and scored each wine without knowing its origin. When the results were tallied, the room fell silent. In the white wine category, the 1973 Chateau Montelena Chardonnay - crafted by Croatian-born winemaker Mike Grgich - took first place. In the reds, the 1973 Stag's Leap Wine Cellars Cabernet Sauvignon, made by Warren Winiarski, defeated some of the most celebrated Bordeaux estates in the world.
