The Côtes de Bordeaux appellation was created in 2009 to merge four existing appellations used in the Bordeaux region of France. These four appellations are The Premières Côtes de Blaye, Côtes de Castillon, Côtes de Francs and the red wines of the Cadillac region. The latter were previously under the appellation Premières Côtes de Bordeaux. The changes were a commercially motivated decision, intended to create unity between these important but lesser known appellations.
They were intended to simplify the Structure of the Côtes de Bordeaux appellation. However, the New banner of the four appellations is not entirely original or easily differentiated from the Old one. It can be said that it has added further complexity to the Bordeaux appellations. This is underlined by the fact that the four components of the appellations are geographically extensive.
