The Cros-Pujol family, owners of Château Grézan, have been committed to an agroenvironmental approach since the end of the 1990s. This approach has been recognized by the certifying bodies and Château Grézan is now HEV certified, a High Environmental Value operator. This recognition was important in order to validate with consumers our desire to defend sustainable viticulture and the implementation of an action plan in this direction.
