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.”

Château de Saint Cosme Gigondas is a blend of Grenache, Syrah, Mourvèdre, and Cinsault. The shade and elevation at Saint Cosme provides a cooler micro-climate than the rest of Gigondas. Whole clusters are fermented with indigenous yeasts and vinified in 15% new barrels, 50% used barrels, and 35% concrete tanks. The wine is bottled without fining or filtration.
