Grenache gris

from Wikipedia, the free encyclopedia

The white grape variety Grenache Gris comes from Spain (it is called Garnacha Roja there), but is also at home in Australia , Bulgaria , France , Portugal and South Africa .

The variety of Grenache is very old and provides round, lush, fruity wine with raspberry or cherry flavor. Since the natural sugar content of the berries is high, it is mainly used in France in sweet wines from Roussillon , the Vin Doux Naturel such as B. Rivesaltes used. The otherwise strong wine lacks acidity when it is developed as a pure white wine .

At the end of the 1980s, the variety was still very widespread in the south of France with over 10,000 hectares , but has largely fallen victim to the official clearing programs. In 2007, around 1,756 hectares were officially planted.

The INRA Montpellier ( Institut National de la Recherche en Agronomie ) used the variety to cross the new breed Aranel .

Ampelographic varietal characteristics

In ampelography , the habitus is described as follows:

  • The shoot tip is open. It is very hairy whitish with a very slightly reddish tinge. The green, slightly bronze-colored young leaves are slightly hairy.
  • The medium-sized leaves (see also the article leaf shape ) are usually five-lobed and only moderately thick. They are light green in color and very shiny. The stem bay is U-shaped open. The leaf margin is finely serrated. The teeth are small compared to the grape varieties. The leaf surface (also called blade) is smooth.
  • The cone-shaped grape is medium to large in size and has dense berries. The round or slightly oval berries are medium-sized and black in color. The skin of the berry is thick. The berries are juicy; the juice is colorless.

The Grenache drives out relatively early. In damp weather during flowering, the Grenache Gris tends to trickle down .

Grenache is mostly with the goblet method educated . It is quite resistant to powdery mildew . It is susceptible to downy mildew , eutypiosis and raw rot . Therefore, the yields can vary between 20 hectoliters / hectare and 80 hectoliters / hectare.

In France 2 clones have so far been selected and approved for commercial cultivation: clone n ° 147, n ° 148, n ° 149 and n ° 150.
