For many years, Grands Vins de Gironde, and, before that, Maison de Luze and De Rivoyre, have held exclusive partnership relations with wine estates in every appellation in Gironde. This partnership means that the château and the company work together, exchanging technical information, collaborating on the blending process and advising each other. The château undertakes to supply its entire production to Grands Vins de Gironde, which is then responsible for distributing it to its customers.
