Clos Saint Jean is a 41-hectare estate in Châteauneuf-du-Pape run by brothers Vincent and Pascal Maurel. Considered by many critics as the preeminent estate espousing the modern style of viniculture in Châteauneuf, the estate is one of the oldest in the region having been founded in 1900 by the great great-grandfather of Vincent and Pascal, Edmund Tacussel. A short time after the founding of the estate, and well before the appellation of Châteauneuf-du-Pape was created (1923), Edmund began estate bottling wines in 1910. 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, limestone-rich soils.

A blend of Grenache, Syrah, Mourvedre, Cinsault, Vaccarèse and Muscardin. The Grenache is aged in concrete for 12 months while the remainder is aged in demi-muid.
