The Vicomte and Vicomtesse Alain de Baritault du Carpia, heirs of the Le Blanc de Mauvesin, cede the property on August 4, 2011 to Lilian and Michel Barton-Sartorius. For eight generations, the Barton family has owned the Crus Classés Langoa and Léoville Barton located in the Saint Julien appellation.
Being equipped with vats of different sizes allows each plot to be vinified separately and thus to have greater possibilities when blending the wines. The vats are thermo-regulated and allow very precise temperature control throughout the fermentation phase. The aging period for the wines is spread over 12 months in French oak barrels. A third are new barrels from 3 different coopers, another third comes from barrels which have already received 1 wine, and finally the last third comes from barrels which have received 2 wines (2 years) from Léoville Barton. Château Mauvesin Barton's wine benefits from all the expertise of Mélanie Sartorius and Bruno Petit associated with the team of consultant oenologist Eric Boissenot.
