César Troisgros, born 5 November 1986 in Roanne, is the eldest son of Michel and Marie-Pierre. He trained at the Institut Paul Bocuse in Écully from 2004 to 2007 before continuing his culinary apprenticeship in major houses such as Michel Rostang in Paris, the Roca brothers in Girona, Spain, Thomas Keller in California in the Napa Valley and a few months with his uncle Claude Troisgros in Rio de Janeiro. In 2011, he decided to go to work in Japan, but the disaster of Fukushima made him postpone his departure. He remained in Roanne to work alongside his father and became involved in family projects, notably in the move to Ouches. Concerned about ecology and biodiversity, the young man cited among his sources of influence the documentary film "Tomorrow (Demain)" and the peasant-philosopher Pierre Rabhi. In 2017, he joined "Vivre bio en Roannais" in the preservation of a bean variety, "the Auvergne bean".
