This is a form of vineyard design (also called mixed set) that was widespread and common in Europe until the 17th century. For practical reasons and to minimise risks, the grape varieties were planted together in a vineyard as a "mixed set" in order to ensure reliability and consistent quality. Therefore, varieties with different ripening times (early to late) and also different acidity levels were mixed. As a rule, up to seven varieties etc. were planted, although these naturally varied according to the wine-growing region. Typical varieties were Chasselas, Elbling, Fütterer, Hanns, Heunisch(Gouais Blanc), Müller-Thurgau, Muskateller, Neuburger, Grüner Hainer, Orléans, Österreichisch-Weiß, Weißburgunder(Pinot Blanc), Spätburgunder(Pinot Noir), Riesling, Silvaner, Traminer, Grüner Veltliner and Zierfandler. The result was often a light red wine, since red wine varieties were also included.
