Chateau de Saint Cosme is the leading estate of Gigondas and produces benchmark wines. Wine has been produced on the site of Saint Cosme since Roman times, evident by the ancient Gallo-Roman vats carved into the limestone below the chateau. The property has been in the hands of Louis Barruol�s family since 1570. Henri and Claude Barruol took over in 1957 and gradually moved Saint Cosme away from the bulk wine business. Henri was one of the first in the region to work organically beginning in the 1970s. Louis Barruol took over from his father in 1992, making a dramatic shift to quality, adding a n�gociant arm to the business in 1997, and converting to biodynamics in 2010.Sauvignon Blanc brings acidity to the blend while Viognier provides fleshiness and attractive notes of stone fruit and flowers.
