Rouge du Pays
Variety of grape
Rouge du Pays, also known as Cornalin du Valais or Cornalin, is a variety of red wine grape.[1] It is primarily grown in the Valais region in Switzerland, where it is often called Cornalin, and the total Swiss plantations of the variety in 2009 stood at 116 hectares (290 acres).[2] It produces deep-coloured wines that typically need aging, and is something of a speciality of Valais.[3]
Cultivating Rouge du Pays requires a fairly warm climate, and the viticultural research institute at Changins has been involved in finding out how its yields can be made more regular than was previously the case.[3]
DNA profiling at UC Davis has established that Rouge du Pays is a cross of Petit Rouge and Mayolet, two varieties from the Aosta Valley in northwestern Italy, close to Valais.[1] Furthermore, Cornalin d'Aoste was established as an offspring of Rouge du Pays.[4]
