Breeder/License holder: Bundesforschungsanstalt für Rebenzüchtung Geilweilerhof,
                                 Siebeldingen/Rheinpfalz

Area planted in England (as at August 2004): large numbers of vines have been planted.
It is among the most important new disease-resistant quality grape varieties world-wide and supplies color-intensive strong red wines.

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

Advantages: Probably the most disease-resistant red wine variety.
A short fermentation on the skins is sufficient for colour extraction.

Disadvantages: Cold and windy sites should be avoided (to minimise coulure).
