Clairette is an old variety that likely originated in southern France often used to produce simple and crisp dry white wines or as a component in a blend such as Châteauneuf-du-Pape blanc. White wines from Clairette have a tradition at Saint Cosme, specifically at Le Poste, where Louis Barroul’s grandfather produced famously long-lived Le Poste Blanc. Limestone soils give Le Poste Blanc a flavor of gunflint and the ability to age for twenty years or more.
