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).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".Prof. Dr. Walter Kutscher
