Château Lagrange was known in the Middle Ages as the Noble House of Lagrange Montei. Records of the successive owners go back as far as 1631. In 1842, the ex-Home Secretary to King Louis-Philippe, Count Duchatel, left his mark on the property and the Médoc by introducing a drainage system in the vineyard. In December 1983, the Japanese group Suntory bought it from the Cendoya family, owners since 1925.
