Significance & conditions
Is a significant variety in Burgenland.
For winegrowers, however, Scheurebe can prove challenging in the vineyard. It is very demanding in terms of location (warm, sheltered from the wind) and soil (good supply of water and nutrients). During flowering, it is particularly sensitive, often resulting in low, irregular yields. It can only tolerate a low lime content in the soil and is especially prone to chlorosis when the weather is cool and wet.

Characteristics of the wine
Depending on ripeness, can yield full-bodied yet mild wines with a delicate muscat flavour. Extremely ripe grapes can produce mild, very smooth Prädikatswein, which pairs excellently with sweet dishes.
