Since 1670, Mas de Libian has belonged to the Thibon family. Located on the right bank of the Rhône, at the foot of the Ardèche gorges, this domaine spans 25 ha and has been organic since its creation. Today, the domaine hold biodynamic certification and the soil is worked by horse and plough. The vines receive plenty of sunlight ,necessary for the production of the native varieties (Grenache, Mourvèdre, Syrah, Cournoise, Vaccarèse), and also has the famous “galets roulés”, or pudding stones and red clay soil; Since 2006, Catherine has been gradually expanding the domaine, acquiring new parcels but also giving much of the land over to polyculture (olive trees, beekeeping etc).

This cuvée owes its name to the proximity of the hillsides to the Arlettes limestone massif which allows the formation of special silicas called "chailles". Syrah vines, 40 years old, have been certified organic since 2016 but biodynamic principles have been used. Naturally, the harvest is manual. The fermentation is carried out with indigenous yeasts and the grapes macerate for several weeks in stainless steel vats with two daily rounds of pump-down and pump-over to extract all their substance and colour. Rich and powerful, Les Chaillés is beautifully tense and tangy. This wine can be enjoyed both young and up to fifteen years later.
