Bordeaux wines that do not fall under a specific appellation are labeled "Appellation Bordeaux" or "Appellation Bordeaux Superieur." The majority of wines made in Bordeaux fall into one of these categories. Wines from these two classifications are made with grapes that come from any appellation within Bordeaux – white or red. Most of the wines are white, and much of the red comes from Entre Deux Mers, where only white wines can bear the namesake appellation on their label. Bordeaux Superior has slightly stricter regulations than the Bordeaux AC.
These two appellations are just across the Gironde river from the Haut-Medoc – a bit northwest of St-Émilion and its satellites. Bourg is the smaller appellation, nestled under the much bigger Blaye. Both have AC status, Cotes de Bourg AC and Cotes de Blaye AC. One step up on the AOC chain is the Premieres Cotes de Blaye AC, producing excellent red wines. Both regions rely primarily on Merlot, blending with Cabernet Sauvignon and some Cabernet Franc. Whites are allowed here too – usually Sauvignon Blanc, creating dry and pleasant wine.
