The red grape variety comes from the Balkan region - probably Montenegro. Synonyms are Kratošija, Prhljavac, Vranac Crmnichki, Vranac Crni, Vranac Ornogorski, Vranac Prhljavac, Vranac Rehuljavi, Vranak, Vranatz, Vranec, Vranek and Vranik. This probably very old variety was already widely cultivated in the Middle Ages. It is probably identical with the Styrian variety Vranek described by Hermann Goethe (1837-1911) in his Ampelographic Dictionary published in 1878. According to DNA analyses carried out in 2004, there is a parent-offspring relationship with the variety Tribidrag (Crljenak Kaštelanski, Primitivo, Zinfandel). This is also the reason why Vranac has often been or is often confused with this mixed cultivar.
The medium ripening vine is moderately resistant to both types of mildew, but is susceptible to botrytis and sensitive to severe frost. It produces deep red wines, rich in extract, tannin and alcohol, with aromas of black and red fruits with excellent ageing potential, which are well suited for barrique ageing. The variety is widely spread in Bosnia-Herzegovina, Kosovo, Croatia (149 ha), Montenegro, Northern Macedonia and Serbia. In 2010, however, only one stock was recorded in Croatia (Kym Andserson).
