Château Siran has long been recognized as one of the top estates in Margaux. The property has been in the Miailhe family for six generations– a total of 160 years. Today, the property covers 88 hectares, with 38 hectares planted to vines. The other fifty hectares are left as woods and meadows, for their beauty and to promote biodiversity, a priority of the Siran team.

The majority of Chateau Siran’s vines are planted in the commune of Margaux, but they also have a very special 11 hectare parcel on the border, which is classified as Bordeaux Superieur and bottled as “Saint-Jacques de Siran”. The terroir here has clay topsoil over the famous Bordeaux sandy gravel subsoil. The vines are planted at a density of 5,000 vines per hectare and average 25 years old. The Miailhe family has practiced sustainable agriculture since 2000 and the vineyards have been certified sustainable, HVE3 since 2018. Only organic fertilizers are used and they work with grass cover and plowing to control weeds. The fermentation happens in stainless steel tanks and the wine is aged for twelve months in French oak.
