Saint Emilion, a pretty, medieval town in the Libourne region of France, listed as a UNESCO World Heritage Site, gives its name to the AOC Saint Emilion (created in 1936) and Saint Emilion Grand Cru (created in 1954) whose areas merge together as well as Montagne, Lussac, Puisseguin, and Saint Georges Saint Emilion, which are geographic satellites and also related appellations, if not as prestigious as Saint Emilion Grand Cru itself. This Grand Cru appellation applies neither to a specific terroir nor to a specific grape variety: only the best wines are entitled to the name belonging to the 1855 classification. They are exclusively red wines and must be bottled at the property and then submitted to a double tasting. The classification distinguishes 2 categories of crus: the first Grands Crus classés (A and B) and the Grands Crus classés. Château Ausone and Cheval Blanc are ranked at the top of the A classified growths, while 13 others are ranked B, including Château Canon, Lagaffelière and Fiegac. The other 57 Grand Crus classés represent only 12% of the appellation. Merlot is its king grape variety, complemented by Cabernet Franc and Cabernet Sauvignon. Wines of great class, wines for ageing that should be tasted at least once in a lifetime.
