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 Côtes-du-Rhône is produced from 100% Syrah and is from the the stony Villafranchian terraces of the Gard. The vineyards are known for their limestone sand, red clay, and pebbles, which give a freshness and intensity to the Syrah grapes. The wine is partially destemmed, fermented with natural yeasts, and vinified in concrete vats.
