Pure Cabernet Franc exclusively from vines over 40 years of age in the commune of Ingrandes de Touraine—part from the sandy gravel terraces of the lieu-dit Louys, and part from hillside plantings in the clay-limestone of Mont Sigou.

This cuvée undergoes alcoholic fermentation in tronconic oak casks with a 10-day maceration, then spends a year in large, very old 25-hectoliter foudres.
