RARE GRAPE VARIETAL RESOURCE

The grape variety "Schwarzblauer Riesling", named after the Ampelograghen Galet, had been widespread in Champagne, Lorraine-Alsace and in the middle and upper Rhine Valley (Palatinate, Electoral Palatinate) since the early Middle Ages. Using the synonym "Noir Menue", its origin can be derived from Lake Van, which is now in Turkey, and from there to northern China and the Indus. The black-blue Riesling was a victim of the Little Ice Age and survived with two copies in one of the oldest Riesling vineyards on the Middle Moselle and was considered extinct until 2008.
