L’Argilus du Roi is a human-sized property in the Saint-Estèphe appellation, established in 2004 and taken over in 2010 by Martial Mignet, a passionate viticulture enthusiast. The estate prioritizes a long-term vision, combining respect for viticultural tradition, the land, and the plant, while integrating modern winemaking methods.

With only 5 hectares of vines, L’Argilus du Roi is one of the smallest châteaux in the appellation and produces a limited number of bottles of its single grand cru. Sustainable farming practices are employed, and the selection process is highly selective, to preserve the wine's elegance and quality.

The plots rest on a typical Saint-Estèphe terroir, composed of gravel, pebbles, and sand, close to the Gironde estuary. The estate claims complete control over the production chain, guaranteeing a demanding wine, on par with its great Médoc neighbors.
