The modern era for Cos d'Estournel really began in 1917, when the estate was acquired by Fernand Ginestet. From Ginestet it passed through the hands of his daughter, Arlette, who married into the Prats family, to her three children, Jean-Marie, Yves and Bruno Prats. Until very recently the Prats family in particular Bruno and then his son Jean-Guillaume have been in charge at Cos, although there have been some subtle changes in ownership. In 1998 the family sold up, and the estate was acquired by the Merlaut family who, as owners of the Taillan Group, are more readily associated with names such asChasse-Spleen, Gruaud-Larose, Ferrière, La Gurgue, Citran and Haut-Bages-Liberal. Nevertheless the Prats family remained heavily involved in the running of the estate, as they were two years later when ownership once again changed, as the estate was acquired by industrialist Michel Reybier. Jean-Guillaume Prats stayed on as president of the property, and he continues to hold this position today.
