The red grape variety is a new cross-breed between Black Morocco x Muscat d'Alexandrie according to DNA analyses carried out in 2013. The previously assumed paternity of Sweetwater (Chasselas) turned out to be wrong. Synonyms are Emil Royal Chernyi, Lady Downe's, Lady Downe's Black Seedling and Lady Dauns Sidling. The cross was made in England in 1835 by M. Foster. The variety is used as table grape.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!Dominik Trick
