The red grape variety is a new variety between Madeleine Angevine x Teinturier (Teinturier du Cher) according to DNADNA analysesDNA published in 2012. The parentage Blauer Portugieser x Teinturier stated by the breeder turned out to be incorrect. Synonyms are Froelich V 4-4, Farbtraube Froelich and Purpur. The cross was made by the breeder Gustav Adolf Froelich (1847-1912). The variety remained unnoticed for many decades and was used as "Froelich V 4-4" in breeding centres. In the 1930s, it was ampelographically processed at the Geisenheim Research Institute and was given the name Dunkelfelder by Dr Helmut Becker (1927-1990), alluding to its unknown origin and dark wine colour.
The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
