Saint-Émilion one of the historic and major wine towns of Bordeaux which is also an appellation located 35km east of Bordeaux on the 'right bank' of the Dordogne River, listed as a world heritage site by UNESCO. It is named after the Saint Benedictine monk Émilion (Aemilianus) and according to legend, he lived here in the 7th century in the forest of Combes in a cave which is now on the grounds of Château Laniote. The town is also a stop on the Pilgrim's Way to Santiago de Compostela and it is one of the oldest wine-growing regions in France, as the Romans planted the first vines here. The predominant grape is Merlot followed by Cabernet Franc and Cabernet Sauvignon. The appellation is responsible for one of the most famous, longlived and expensive wines of France including Château Cheval Blanc, Château Ausone, Château Angélus, Château Figeac and Château Pavie. The Saint-Émilion area is covered with a thick molasse layer of calcareous, sandstones, shales and conglomerates of shallow marine deposits. The appellation consists of 5 main areas based on their type of soil: Côte Sud, or South - Graves de Figeac - the West coast - the North coast and the plateau of St-Martin. Saint-Émilion also has four satellite areas including Lussac-Saint-Émilion, Saint-Georges-Saint-Émilion, Puisseguin-Saint-Émilion and Montagne-Saint-Émilion all of them covering distinct, slightly smaller areas immediately northeast of Saint-Émilion. There is a classification system since 1955 which is updated every 10 years or so (last being in 2012), and consists of the following levels: Premier Grand Cru Classé A, Premier Grand Cru Classé B, and Grand Cru Classé - 18 Premiers Grands Crus Classés and 64 Grands Crus Classés.
