The estate lies in the heart of Gigondas where 15 hectares of vineyard grow in the shade of the Dentelles de Montmirail mountain. In addition to the estate-grown wines labeled “Château de Saint Cosme,” Louis Barruol buys grapes from contracted growers, labeling these “négociant” wines simply as “Saint Cosme.”

Saint Cosme Châteauneuf-du-Pape comes from three climats, the most famous of which is the plateau of La Crau with its distinctive galets over clay, bringing power and structure to the blend. The climats of Valori and Christia are on sandy soils, giving the wine its perfume and freshness. The wine is a blend of Grenache Mourvèdre, Syrah, and Cinsaut, made with whole cluster fermentation from indigenous yeasts, is aged for 24 months in old 228-liter barrels, and bottled without fining or filtration.
