You will barely come across another region on our planet where so many different types of soil are to be found in such close proximity. While you find various types of schist soil between St. Paul de Fenouillet and Cases de Pène, the vines surrounding the village Latour de France grow in calcareous clay soil, which also hold heavy ferrous parts all together called Terra Rossa soil. Following the course to Rasiguères there is a wild mix, depending on its alignment, of schist, granite, and lastly turning into sandy gneiss soil when you reach Caramany and Cassagne. These diverse terroirs, in connection with old vines to almost not be found anywhere else make this region one of the most interesting ones for viniculture in the years to come.
