In the Minervois, as in all the French appellations, moreover, the INAO, the national institute of origin and quality, constrains every winemaking estate to respect the nature of the different grape varieties and their respective percentages.

Nothing forbids the winemaker to vinify Mourvèdre, Syrah or Carignan separately and to make separate cuvées from them.

All the soils at Centeilles are clay-limestone on siliceous sandstone, but we can say that these Carignans, more than a century old, are planted in the poorest and stoniest soils of the entire holding.

Because of the types of soil and the age of the vines, the yields are very low, about 30 to 45 hl/ha, and some years, the productions can even become confidential (22 ha/hl around the church in 1992).
