Because of the influence of the Gironde the appellation 'Blaye-Cotes de Bordeaux' benefits from a micro climate particularly favourable to the cultivation of the grape.
The qualities of this terroir, ideal for the production of fine wine, have been recognised since Roman times.
The proximity of the estuary gives the terroir its typical characteristics. Wines profit from a clayey gravelly soil of moderate richness with high macro porosity.
The play of these factors ensures that the grapes ripen well.
