The white variety is amongst the oldest cultivated vines in Europe, and is known as the Sylvaner in Austria and Switzerland, and Silvaner in Germany. The crossing is Traminer x Österreichisch Weiß, and is often called the 'Österreicher', or Austrian.
Origin
Sylvaner is one of the oldest autochthonous grape varieties in Austria. From here, the variety made its way to Germany, where it was once known as “Österreicher”.
Vineyard area
Sylvaner was still a significant variety in Austria in the mid-20th century. However, it has considerable disadvantages compared to the Grüner Veltliner, such as low resistance to winter frosts and a high susceptibility to Peronospora, oidium and botrytis. The variety’s growth also proved too weak for Lenz Moser’s high vine training system, which gained widespread use with the more-favoured Grüner Veltliner. Between 1999 and 2020, the already small area under this variety decreased further in size.

Significance & conditions
The variety has very little significance in Austria, though it plays a more important role in Germany. Sylvaner requires very specific conditions in the vineyard and is especially susceptible to chlorosis if the soil is too high in lime.
