"Wander into the vine-draped courtyard of the Confrérie Saint-Etienne d'Alsace in Kaysersberg, France and you’ll have no idea of the amazing secrets that lie beneath the 14th-century castle and its stone walls—some 65,000 bottles of Alsatian wines, collected from 1948 to modern day. "Every wine in our cellar is unique," says Guillaume Bauer, general manager of Château de la Confrérie Saint-Etienne d'Alsace." - Jillian Dara
