The vines of Château Mauvesin Barton are situated in the appellation “Moulis en Médoc”, halfway between Margaux and Saint Julien. It is the smallest appellation in the Médoc with 610 hectares. It does however combine exceptional soils with pure graves hills, clay and a checky subsoil.
At Mauvesin Barton, the soil is a mixture of clay and limestone, ideal for the Merlot grape ; then a part of fine gravel and sand more suitable for Cabernet Sauvignon.
The parcels of vines which covers 50 hectares were planted at different periods and the average age is at present about 35 years. This means that production is limited with greater concentration and better quality. The modification of certain parcels began in 2012 with the plantation of 6 hectares of vines and the uprooting of one parcel.
When the harvest starts special care is taken to obtain maximum quality.
A vibrating container is used in order to ovoid disturbing the crop when unloading, without compressing the bunches.
An additional step to maintain the quality of the crop is the investment in an optical sorting machine which eliminates the grapes of lesser quality, retaining only the best quality. This optical sorting system is not yet generally adopted in this appellation.
