The red grape variety is an interspecific new variety between Cabernet Sauvignon x Cynthiana (Norton). The part of the name "Crimson" (dark red, blood red, purple, carmine) refers to the colour of the wine. It contains genes of Vitis aestivalis x Vitis vinifera. The hybrid was crossed in the USA in 2001 by Lucian W. Dressel. In 2016, 1.3 hectares of vineyards were recorded in the US state of Kentucky (statistics Kym Anderson).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
