The largest fine-wine region on earth, and the most mercantile: a vineyard organised around a port. Rome planted the first vines, but the marriage of Eleanor of Aquitaine in 1152 opened three centuries of English trade in claret, and the négociants of the Chartrons quay built the machinery — brokers, merchants, la place de Bordeaux — that still sells the wine of thousands of châteaux.
Everything divides along the water. Cabernet Sauvignon on the gravel banks of the Médoc and Graves; Merlot and Cabernet Franc on the limestone and clay of Saint-Émilion and Pomerol; the green hills of Entre-deux-Mers between the rivers, the botrytis mists of the Sauternais to the south. One name, one market — and a dozen countries of wine inside it.
