The red grape variety probably originates from the USA. Synonyms are Black Herbemont, Bottsi, Brown French, Devereux, Dunn, Herbemont's Madeira, Hunt, Kay's Seedling, Madeira, McKnee, Neal Grape, Neil Grape, Thurmond, Warenton, Warren and Warrenron. It should not be confused with the new variety Hunt because of the synonym. According to DNA analyses carried out in 2021 by Dr Jeronimo Rodrigues (PhD Biochemistry, UCT) in South Africa, it originates from a cross between Chasselas x unknown partner. The US botanist Thomas Volney Munson (1843-1903) assigned the father variety to the species Vitis bourquina. Accordingly, it would contain genes from Vitis aestivalis, Vitis cinerea and Vitis vinifera.
