Blauer Portugieser is probably a crossing between Sbulzina and Sylvaner. It is identical to the “Português Azul” variety in Portugal.
Vineyard area
Grows mainly in Niederösterreich but is significantly declining in importance. The total area planted with this variety increased steadily between 1999 and 2020.

Characteristics of the wine
Characteristics of the wine
Higher yields result in simple, pale red wines that mature quickly and age prematurely. In good vintages, yield restriction enables Blauer Portugieser to deliver dense, extract-rich red wines.
