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 Crozes-Hermitage is produced from 100% Sérine, an ancient and local variety of Syrah that is markedly different from modern selections. It is more oval, with lots of space in the bunch, resulting in a very aromatic wine. It is sourced from the hillside vineyards of Erôme, Gervans, and Larnage in the northern part of the appellation. It is made from 100% destemmed grapes, fermented with indigenous yeasts, aged in 20% new 228-liter barrels, and bottled without fining or filtration.
