A native of the Médoc region, Jean-Guillaume has been president and CEO of Cos d’Estournel for 14 years. During this time, he created Cos Blanc from scratch, and also brought innovation to the estate, notably with the creation of the new vat room. Then, Jean-Guillaume Prats left Bordeaux and for more than 5 years, he was president of LVMH wines worldwide: 17 estates in total. An extraordinary adventure during which he relaunched Cheval des Andes in Argentina and created Ao Yun in China, then among others Chandon in India and China and Te Wahi in Central Otago. Later, Jean-Guillaume Prats was President of Domaines Baron de Rothschild (Lafite).
Today, Jean-Guillaume Prats has joined forces with Stéphane Courbit, former President Nicolas Sarkozy and his wife Carla Bruni to buy Château d’Estoublon in Provence. The estate gathers 200 hectares, of which 20 are planted with vines and 120 with olive trees. The estate produces red, rosé and white wines under the Baux-de-Provence appellation. The team has also created a Provençal rosé called Roseblood and they produce a top-of-the-range olive oil (the only oil listed as part of the Comité Colbert).
In parallel, Jean-Guillaume Prats remains in Bordeaux alongside Jean-Hubert Delon, owner of Domaines Delon: Châteaux Léoville Las Cases, Potensac and Nénin. His appointment as Vice-President of Domaines Delon accompanies the creation of the new vat room and cellar overlooking the great enclosure of Las Cases in Saint-Julien.
