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 is the flagship cuvée of the domain, made from its best plots, namely the localities of Montalivet, La Crau, Bois Dauphin and Pied de Baud. The very old vines of Grenache are located there. The vats are filled using gravity and the harvest is destemmed at about 60%. Vinification occurs "pre-blending", that is to say that the three grape varieties (Grenache, Mourvèdre and Syrah) ferment together, aiming at creating harmony as soon as vatting takes place. Maximum extraction takes place but the ageing process will aim to make the tannins fresh thanks to the slow oxygenation operating through the pores of the foudres and demi-muid barrels. Thanks to this careful process, ageing potential can reach twenty years. When drinking, the fruit is exuberant, the substance is dense and tannins are robust.
