Château l'Arrosée was originally named after an underground spring. For many years, it was owned by François Rodham. In 2002, Roger Caille purchased it and began managing it with his son, Jean-Philippe. Though they made many investments in order to tap into the estate's great potential, in October 2013, they sold it to Domaine Clarence Dillon, the owner of Haut-Brion and La Mission Haut-Brion. L'Arrosée's vineyards are now be incorporated into the neighboring Château Quintus, a property Dillon bought in 2011, which had been formerly named Château Tertre Daugay, and renamed Quintus after the Gallo-Roman tradition of calling their fifth child Quintus.
