The red grape variety comes from Turkey. Synonyms are Ada Karasi, Adakarassy, Avsa Adasi, Avsa Island, Balikesir, Erdek and Noir des Îles. It should not be confused with the Calkarasi, Horozkarasi, Kalecik Karasi or Papazkarasi varieties, despite synonyms or morphological similarities that seem to indicate this (but it is assumed that some of them may be identical). The late ripening, high-yielding vine is susceptible to powdery mildew and needs plenty of sunshine. It produces colourful, aromatic red wines with soft tannins and ageing potential. The variety is mainly cultivated on the island of Avsa in the Sea of Marmara. There are also smaller stocks in the two provinces of Balkesir and Tekirdag in the Marmara region. In 2010, a total of 69 hectares of vineyard area were designated in Turkey (statistics Kym Anderson).
