Blauer Portugieser (Português Azul)
Origin: Portugal. This variety was brought from Porto to Vöslau by Baron von Fries at around 1770.
Parentage: Blauer Portugieser is a cross between Blauer Zimmettraube and Sylvaner. The Blauer Portugieser is identical with the variety Português Azul in Portugal.
Vineyard area: 1,263 ha, 2.7 %. Grows mainly in Niederösterreich, but is declining in significance. Its growth area decreased by 31.2% between 1999 and 2009.
Important ampelographic features
Leaf: circular, with five to seven lobes.
Grape cluster: medium-sized; compact berries; conical, shouldered, sometimes with small wings; oval grapes with blueish-black colour.
Ripening time: early- to mid-season
Significance, conditions: The Blauer Portugieser is important in the Thermenregion and the northwestern Weinviertel.Its proneness to winter frost, Botrytis, oidium and peronospora make production difficult.
Wine: Higher yields bring simple, neutral and light-coloured red wines that mature and age quickly. Good vintages and yield limitation allow Blauer Portugieser to deliver strong and extract-rich red wines.
