The red grape variety (also Rogers 39) is an interspecific new variety between Carter x Black Hamburg(Muscat d'Hamburg). It contains genes from Vitis labrusca and Vitis vinifera. The hybrid was crossed in 1885 in Salem/Massachusetts by the private breeder E. S. Rogers. It is used in the USA as a wine grape. In 2016 no stocks were reported (Kym Anderson).

As honorary chairman of the Domäne Wachau, it is the easiest and quickest way for me to access the wein.plus encyclopaedia when I have questions. The certainty of receiving well-founded and up-to-date information here makes it an indispensable guide.
