The variety Gouais Blanc (France) is genetically identical to Weißer Heunisch (Germany), although the development of the two varieties has been different.
Many of the synonyms were partly used "crosswise" for several Heunisch varieties. The German name Heunisch dates back to the early Middle Ages and was allegedly first mentioned in the 11th century with "hunisce druben". It associates with the Huns and that it was supposedly brought to Europe by them. However, this hypothesis is difficult to prove. For many centuries, the terms "Heunisch" (for "coarse") and "Fränkisch" (for "fine") were the only wine or quality designations and did not refer to a specific variety. A reliable mention was made in 1546 in the famous "Kreütter Buch" by Hieronymus Bock (1498-1554: "Die großen feiste (dicke) Hynische Drauben, welche umb (wegen) ihrer schnelle würckung willen, von etlichen scheiss Drauben genandt werden". The varieties of the Heunisch group:
There are many hypotheses about the origin of the French name. The most likely assumes a naming commune, with the following being possible: Gouaix...
