Bruno Prats (Cos d'Estournel) and Paul Pontallier (Chateau Margaux) decided to look for high quality land in Chile to plant a new vineyard. Their third associate was their Chilean friend, agronomist and oenologist Felipe de Solminihac. In 1990, they acquired 45 acres in the 'Quebrada de Macul' - historically the heart of the Maipo Valley vineyard. Viña Aquitania was born. In January 2003, Ghislain de Montgolfier (CEO of Bollinger), became the fourth partner.
