Gray Portuguese

from Wikipedia, the free encyclopedia

Grauer Portugieser is a white wine variety . The variety Grüner Portugieser evolved from it, probably through mutation . The almost forgotten grape variety came back into focus when Ferdinand Regner et al. proved in 1997 that the new cultivation of the Jubilee vine originated from a cross between Grauer Portugieser and Frühroter Veltliner . In 1922, Fritz Zweigelt looked intensively into the possibilities of the variety.

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is only hairy like a cobweb. The green young leaves with bronzed areas are shiny
  • The large, medium-green leaves are three-lobed to five-lobed. The stem bay is open in a U-shape. The sheet is serrated to a point. In comparison to the grape varieties, the teeth are set narrow to medium-wide. The leaf surface (also called blade) is smooth or only slightly blistered.
  • The cylindrical grape is medium to large in size and has dense berries. The round berries are small to medium-sized and red-gray in color.

The grape variety that emerges early ripens about 6 days after the Gutedel and is therefore considered to ripen early within the white grape varieties, so that it can also ripen in relatively cool locations.
