The white grape variety originates from Ukraine. It is named after an old name of the town of Sudak in the Crimea. Synonyms are SD-56 and Soldaiya. In Crimea, it is used as a blend in fortified wines, e.g. by the Solnechnaya Dolina (Sun Valley) winery. It is also used as table grape. No population was recorded in 2016 (Kym Anderson).

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
