The red grape variety comes from Russia. Synonyms are Koumchatzky Noir, Koumshatsky Cherny, Koumchatzky Tcheurny and Kumshatskii Cherny. The parentage (parenthood) is unknown. The variety is grown in the southern part of Rostov near the border with Ukraine and was named after a local town. It is mainly used there for sweet sparkling wines. However, no stock was reported in 2010 (statistics Kym Anderson). There is also a white variety called Kumshatsky Bely.
