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 Condrieu is produced from fully-ripened Viognier which Louis Barruol believes is essential to achieving the variety’s full potential. “But ripeness must not imply excessive alcohol,” says Barruol, “We seek balance.” The wine is matured for eight months in used 228-liter barrels, and undergoes full malolactic fermentation on fine lees for 12 months.
