Designation (also original variety) for a grape variety that is considered the origin (mother or father) of many other varieties within a large group in the grapevine family tree. By their very nature, these are exclusively very old grape varieties. Most of the cultivated varieties grown in Western Europe today can be traced back to a relatively small group of leading varieties and their spontaneous (natural) crossings. The most important is probably Gouais Blanc (Heunisch or White Heunisch), from which well over 100 varieties in many European countries are descended. These include Riesling (Germany), Bourboulenc and Chardonnay (France), Xinomavro (Greece), Blaufränkisch and Silvaner (Austria) and Furmint (Hungary).

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
