The terroir of the Cause is by far the most mystical of all the vineyards in Cahors. For thousands of years, men have found a point of equilibrium between heaven and earth. Not far away in a clearing surrounded by forest stands in silent a prehistoric megalith. The steeple of the village is on the horizon and in the middle, stands the Prieuré which is testament to the sacred spirit of this clearing in the vineyard. Built on the limestone headland which dates from the Jurassic period, the Prieuré de Cénac dominates both the valley and hills of the Cause. Here the land rises to nearly 300 metres above sea level. Although this is not high for Hervé as a winemaker from the Andes, he was immediately impressed by the quality and diversity of the soils. The calcareous base, the main characteristic of the Cause, Argentina, is covered with clay that is very rich in iron and manganese. The walls and facades of the Prieuré itself reveal the richness of this incredible and fascinating terroir.
