The red grape variety (also Jaeger 50) is an interspecific new variety between Jaeger 43 x Herbemont. It was named after the US winemaker Nicholas Longworth (1783-1863). There are genes from Vitis aestivalis, Vitis cinerea, Vitis lincecumii and probably also Vitis vinifera. Incidentally, the same parents also gave rise to the Kiowa variety created by the botanist Thomas Volney Munson (1843-1913). The hybrid was crossed in 1880 in the USA by the breeder Hermann Jaeger (1844-1895). No stocks were reported in 2016 (Kym Anderson statistics).
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.
