Schiava grossa or Vernatsch) and Riesling. Herold was working at a plant
breeding station in Lauffen in the Wurttemberg region of Germany. This

is today widely grown in Germany, as well as parts of Austria, Switzerland, and
Italy (and to a much lesser extent in Canada, England, and even Japan). In the

can yield very large crops, which can create thin, dilute wines but when properly
managed in the vineyard and if harvested at optimal maturity it can create
exotically perfumed wines that are golden straw yellow in color,
offer up fresh
aromas of tropical fruits such as mango, pineapple and hints of fresh green
apple on the nose. On the palate they have a rich creamy texture with rich
fruity flavors of pears, citrus, apples, red currants, and apricots balanced by
good acidity and a riesling like hint of petrol on the finish
