In 1908 Louis Calas bought 3 hectares of vines and a winegrower's house in Pouzolles to settle his son, also called Louis. Nearby the house in Pouzolles there was The Castel of Saint Preignan which existed for approximately 12 centuries, and it was for a long time the property of the bishops of Bézier. The Castel was built on a swamp, so the soil consist of blue clay which allows the roots of the vines to dive deep and find some water when it is a drought everywhere else. The Calas family bought the Castel in 2005, and now Philippe and Pierre Pastor, the 5th generation, are using the some house near by to produce their wine,
