At the beginning of the 20th century, the Sabon family came into possession of this lieu-dit. The domain was then founded in 1932 by Séraphin Sabon when he married Marie, daughter of Romain Jausset who owned a few parcels, including this one in Châteauneuf. Today, the domain is in its 4th generation and spans 20 hectares (and 10 supplementary hectares in the Côtes-du-Rhône). Grenache is the dominate variety that is blended with Syrah, Mourvèdre and Cinsault and, in smaller portions, Counoise, Vaccarèse, Muscardin, Picpoul Noir and Terret Noir. White varieties include Grenache, Picpoul and Picardin. Old barrels give the wines of Clos Mont Olivet their lightly oaked characteristic. This domain is Châteauneuf at its best thanks to parcels situated in some of the finest areas of the appellation. These wines have immense ageing potential.

The Côtes-du-Rhône of Clos Mont-Olivet comes from about thirty-year-old vineyards located north of Bollène, on the border between Vaucluse and Drôme Provençale. This is the "la Blancherie" locality on a Wurmain alluvial soil. Filled by gravity, concrete vats accommodate alcoholic and malolactic fermentations. Then the wine is aged in foudres and barrels which have held several wines. The aim is to obtain an indulgent and fresh wine, to drink in 3 to 5 years.
