Significance & conditions

The variety thrives on sites of medium elevation, where it buds early as a result. As a “PIWI” (fungus-resistant) variety, its resistance against oidium and Peronospora is very high, but it is prone to grape withering and stem paralysis.

Characteristics of the wine

With their muscat and citrus aromas, the wines are reminiscent of Muskateller. They are dense, rich in extract and have an intense acidity, which makes them good candidates for Sekt production. The high tannin content, however, means that fining is required.
