The red grape variety originates from the Balkan region; probably Bulgaria or Greece. Synonyms are Ceaus, Ceren, Chambata, Chefka, Cheren Chaush, Chevka, Chondromavro, Gordo Cheren, Kara Tchaoush, Mavrouti, Nazlikara, Nazlun Kara, Nichefika, Nichefka, Nicheftka, Nichevka, Shevka, Sefka Nichevka, Sefko, Sephka, Sephko, Sevka, Slivenska Cherna and Sramezhlivo Grozde. The ancestry (parentage) is unknown. Despite the synonym, it should not be confused with the independent variety Chondromavro. The biologist Dr. José Vouillamoz distinguishes two varieties, namely Sefka with origin Greece and Shevka with origin Bulgaria. They are similar in DNA profile, but in his opinion they are not identical. Only one variety is listed in the VIVC catalogue. It is used as a winepress and table grape.
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
