The vineyards of Clos Saint Jean are primarily located in the region of Châteauneuf known as La Crau. This plateau is the most iconic of the many terroirs of Châteauneuf-du-Pape – iron-rich red clays topped with galets.  While about 60% of the vineyards of Clos Saint Jean are located on this terroir, more specifically in the lieu-dits of Côteau de Saint Jean and Cabane de Saint-Jean, another 40% are located on alluvial clay and sandy soils adjacent to the plateau. They also own a small parcel of Mourvedre in the lieu-dit of Bois-Dauphin near Château Rayas planted on sandy, limestonerich soils.

"The lush, fruit-forward 2016 Chateauneuf du Pape is a good introduction to the domaine's Grenache-dominated style, boasting copious amounts of cherry and apricot fruit. It's full-bodied and velvety in texture, with attractive hints of licorice emerging on the long finish. With its slightly more prominent acidity, it should drink well for longer than the 2015 or 2017 versions." Joe Czerwinski, The Wine Advocate.

A blend of Grenache, Syrah, Mourvedre, Cinsault, Vaccarèse and Muscardin, the Châteauneuf-du-Pape Vieilles Vignes is made from old vines located in and around Le Crau. The Grenache is aged in concrete for 12 months while the remainder is aged in demi-muid.
