Château Sixtine has been owned and operated by the Diffonty family since 1900, when Félicien Désiré Diffonty bought property between Orange and Avignon. The family had been farming in the region since the late 17th century. But in the 20th century they became vignerons, and today the 38-acre estate is run by Jean Marc Diffonty, great-grandson of the founder. Sixtine owns parcels in legendary vineyards, including La Crau, and grows the grapes of the Châteauneuf-du-Pape appellation: Grenache, Syrah, Mourvedre, Roussanne and Clairette. The estate’s wines frequently win awards at French wine competitions and American reviewers often rate the wines in the low to mi-90s.
