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.

This white Châteauneuf comes from soils dominated by sandy clay, south-facing. Harvested in the early morning so as not to have to cool the harvest, the grapes are pressed and spend the night in static cold débourbage. Some of the Roussanes (about 10% of the total) will be aged in new barrels and the rest in stainless steel vats. The Roussanes are particularly expressive, showcasing aromas of exotic fruit, peach and apricot.
