Genetic studies have revealed that Pinot Noir is probably one of the two ancestors (the other being the humble Gouais) of some of the most important vines cultivated in Europe today. It is certainly a particularly ancient variety, and originally from Burgundy. Pinot Noir, with its associated clones, is found all over Switzerland, but it is only in the eastern region that it dominates production. It is either produced as a varietal or blended with other grapes. These blends are known as Salvagnin in Vaud and Dôle in Valais. Depending on where it is grown, it can produce a wine that is either light and fruity, or rich and full-bodied.
