Wine Character - colour:
- 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:
- surface undulation:
- petiolar sinus:
The leaves are not attractive to phylloxera, so leaf galls do not develop. It is
comparable with any Vinifera in this respect.
Grape bunch: - size: medium-large
- density: loose
Berries: - size:
- skin colour:
Time of veraison: middle-early
Time of harvest: middle-late; grapes can be left on the vine for a very
Grape yield: very high
Wood ripening: good to very good
Winter hardiness: very good (-20 °C causes no problem)
Wood colour: yellow-brown
Resistance against - Oidium: very high
- Peronospora: very high (in bad years a late infection may be a problem)
- Botrytis: high
- Roter Brenner:
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.
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.
