Mazeyres is a pretty castle, in the center of the district of the same name, on the outskirts of Libourne. This means that we are here at the south-western limit of the appellation, on soils of sand larded with clay and gravel which, if they often limit the depth and the long-keeping capacity of wines , can give tasty results when done well. This is the case here where the very competent Alain Moueix does an efficient and increasingly remarkable job.
