Côtes de Bourg is one of the oldest Bordeaux AOCs (“Appellation d’Origine Contrôlée”). It is situated 35 km north-west of Bordeaux on the Right Bank of Garonne and Dordogne rivers around the town Bourg-sur-Gironde.
First “vitis biturica” in Côtes de Bourg were planted by the Romans. The combination of rich soil (range of gravel, alluvium, clay and limestone), climate and exposition of the east bank were ideal for cultivating the grape. In the Middle Ages Bourg was a major port for wine and the vineyards grew around the town.
