Winegrowers Supplies -  Vine variety information

Orion  (originally known as Gf. Ga-58-30)

Mother: Optima
Father: Villard Blanc (Seyve Villard 12-375)

A white Piwi/disease-resistant variety.

Year of breeding: 1964 (Prof. Dr. h.c. G Alleweldt)
Country of origin: Germany
Breeder/License holder: Bundesforschungsanstalt für Rebenzüchtung Geilweilerhof,
Number of clones: 0

Year of entry into the German Federal Office's Varieties Register: 1994
Area planted in Germany in :        hectares
Area planted in England (as at August 2004): large numbers of vines have been planted

Wine Character - colour: 
                      - bouquet: 
                      - palate: the wine is very easy to drink, with a fresh pleasant soft acidity.
I call it a two-bottle wine, meaning you feel like another glass after the first bottle is empty. The wines ripen quickly and should therefore be bottled early.

Time of bud-burst: middle-early

Strength of growth: strong
Growth of side-shoots: quite strong

Flowering time: a little before Müller-Thurgau
Flowering strength: high

Leaf: - size:                                    - shape: 
        - colour: 
        - surface undulation:                - petiolar sinus: 
The leaves are not attractive to phylloxera, so leaf galls do not develop.

Grape bunch: - size: medium-large        - density: loose
Berries:        - size:                            - shape: 
                   - skin colour: 

Time of veraison: middle-early
Time of harvest: middle-late; grapes can be left on the vine for a very long time.

Grape yield: very high
Must-weight: medium
Must-acidity: medium

Wood ripening: good to very good
Winter hardiness: very good (-20 °C causes no problem)
Wood colour: yellow-brown

Chlorosis resistance: 
Resistance against - Oidium: very high
                       - Peronospora: very high (in bad years a late infection may be a problem)
                       - Botrytis: high               - Roter Brenner: 
                       - Phomopsis                   - Stem-atrophy: 
In the UK in extreme weather conditions (wet followed by hot sun) and with dense foliage, it can be slightly susceptible to Oidium and Peronospora; however, it is one of the most resistant of all varieties.

Preferred soil: 
Suitable rootstocks: SO4 or 5C

Normal stem height: 
Normal row spacing: 1.8 to 2.0m
Vine spacing in the row: 

Winter Pruning: 8 to 10 eyes/buds per sq. metre of land occupied by the plant.

Advantages: Very high yield. Spraying is hardly ever necessary, so ideal for Organic Wine. The wine is very easy to drink, and is ideal for blending with strong muscat varieties such as Schönburger.

Disadvantages: Strong growth of side-shoots. Wines are best drunk young.
