Biodynamic. It's drawn from 40-year-old biodynamically managed vines rooted in a range of Mas de Libian's highland Ardèche soils: some galets roulés (rolled alluvial 'pudding stones'), some sandy clay and some lower-lying parcels on limestone soils. The blend is 75% Grenache with 25% Syrah. The varieties co-ferment and mature in a mix of Stockinger foudre and cement vats. Thibon included some ripe Syrah stems in this year's ferment to add freshness and lift.
