The estate was founded by two families, the Chatonnets and the Cantenants. In more recent times, for two centuries, Chateau Ausone was the property of the Vauthier and the Dubois-Challon families. Today it belongs to Alain Vauthier and his sister Catherine, who bought their aunt Helyette Dubois-Challon’s share in 1997. Alain Vauthier runs the estate and makes the wine. Since 2005 his daughter Pauline, a qualified oenologist, has been working with him.

The site is exceptional: divided between the limestone plateau and Saint-Emilion’s calcareous clay slope, facing east-south-east and sheltered on its north and west sides, Ausone was one of very few Saint-Emilions to come unscathed through the terrible frosts of February 1956. The 7 hectares of vineyard, lying in a single plot around the chateau, are planted with 55% of Cabernet Franc and 45% of Merlot. The vines are very old, with an average age of 50 years.
