Regent is a German grape variety, which originated from a cross of Diana (Silvaner x Muller-Thurgau) x Chambourcin. The crossing was performed in 1967 by Prof. Gerhardt Alleweldt (1927-2005) at the Institute Geilweilerhof in Siebeldingen in Rhineland-Palatinate. After the breed was initially tested under the study number ‘Geilweilerhof 67-198-3’, this breed was introduced under the name Regent. On 4 March 1994 plant breeders' rights were granted in Germany. Community plant variety rights were granted on 15 October 1996.
The breed gives small to medium sized blueberries to small to medium sized slightly compact bunches. The berries mature in the Netherlands from the end of September and become very sweet with a spicy flavor. The sticks grow strongly with a half-upright growth mode. The leaves color in autumn nice red. In windy and cool places, the fruit setting may leave a good taste. The degree of resistance to the real and false mildew fungi is reasonable to good. High infection pressure or adverse conditions may cause deterioration, but this is usually less severe than non-resistant varieties.
In the early years Regent often suffers from discoloration of the leaves due to a magnesium defect, a characteristic he inherited from Chambourcin.
Regent gives very dark tannine-rich wines with aromas’s of forest fruits (wine type Bordeaux). Due to the large quantities of tannins, Regent's wine is often found difficult to access.
