The historic Château de Saint Cosme in Gigondas has the site of a Gallo-Roman winery, complete with vats cut into the rock, in its grounds. The property has been in the same family since the end of the 15th century and 15 generations of wine makers have followed on from each other. Today, the vineyard comprises 22 hectares of old vines (more than 60 years old) and yields low volumes of grapes. The vines enjoy a cool climate that gives the wines their balance, finesse and freshness. The domain was following the principles of organic farming as far back as the 1970s and today it avoids herbicides, chemical fertilisers, pesticides and synthetic products completely. The Château supplements its own output with a négoce business, working with winegrowers who are passionate about their trade. Wines from this domain are fairly representative of their appellation and have plenty of depth.

The very old Grenache vines have benefited from a limestone hillside terroir in the Le Poste locality. This parcel is unique within the domain, thanks to the surrounding broom, mulberry, thyme, hawthorn, fennel and rosemary vegetation. It is in this most beautiful place that the grapes grow and are harvested by hand. Vinification is performed in whole bunches, and the wine is matured for 12 months in pièce barrels. The wine is bottled without filtration. Tasting reveals a seductively intense bouquet of red berries and flowers such as violet. The palate is silky, with a very pleasant saline sensation at the finish. A very attractive wine; the usual advice is to lay it down for many years.
