Château Magnol's winegrowing history goes back to 1842 when Monsieur Delisse, an experienced agronomist, consolidated the vineyards surrounding the former Château du Dehez. The estate was purchased under the name "Château Magnol" in 1978 by Barton & Guestier, who undertook major investments in the vineyards and cellars. The efforts were crowned with successs when Château Magnol was classified Cru Bourgeois in 1987.
