Ch?teau de Saint Cosme is the leading estate of Gigondas and produces the benchmark wines of the appellation. The property has been in the hands of the Barruol family since 1570. Louis Barruol took over from his father in 1992 making a dramatic shift to quality and converting to biodynamics in 2010. 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 ?Ch?teau de Saint Cosme,? Louis Barruol buys grapes from contracted growers, labeling these ?n?gociant? wines simply as ?Saint Cosme.? Saint Cosme C?;tes-du-Rh?;ne is produced from 100% Syrah and is from the rocky and cool vineyards of Vinsobres and the stony Villafranchian terraces of the Gard. Vinsobres brings freshness and complexity while the terraced vineyards of the Gard contribute color and power. The wine is partially destemmed, fermented with natural yeasts, and vinified in concrete vats.
