Saint-Joseph or St.-Joseph is a French wine Appellation d'Origine Contrôlée (AOC) in the northern Rhône wine region of France. Though the appellation covers the largest amount of land, it is second in actual size under vine to Crozes-Hermitage, an appellation with which it shares much regarding style and prestige. While St.-Joseph is primarily a red wine region based on the Syrah grape, there may be up to 10% Marsanne and Roussanne.
