The red grape variety (breeding no. GF 67-198-) is an interspecific new variety between Diana (1) x Chambourcin. It contains genes from Vitis labrusca, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1967 by grower and later head of the Geilweilerhof Institute Dr Gerhardt Alleweldt (1927-2005) in Siebeldingen (Palatinate, Germany). Due to its favourable characteristics, the Regent variety was a parent of the new varieties Cabernet Blanc, Cabernet Colonjes, Cabertin, Calandro, Julius and Reberger.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
