Located about 50km north of Bordeaux, St-Estèphe is home to some of the left bank’s key châteaux. Although the appellation has long been on the premium wine map, recent cellar innovations at top estates such as Château Calon-Ségur, Château Montrose and Château Cos d’Estournel have re-kindled interest in this traditionally rustic corner of the Médoc.
