The wine region of Saint-Émilion centres on the commune of the same name. There are several villages around the region that share the Saint-Émilion name, such as Montagne-Saint-Émilion and St-Georges-Saint-Émilion, and are permitted to label their wines under the same name. The area is bordered to the west by Pomerol. Merlot is the dominant grape in this area, followed by Cabernet Franc. The climate and damper, cool soils of the area makes it difficult for Cabernet Sauvignon grapes to fully ripen and as such is less often used. The wines take a little longer to mature than the ones in Pomerol but are still able to be drunk relatively young for a Bordeaux (4–8 years). In favorable vintages the wines have a good aging potential.
