'sour black') is the principal red wine grape of the uplands of Naousa in the regional unit of Imathia, and around Amyntaio, in Macedonia, Greece.

[1][2] This grape is primarily cultivated in Naousa, Goumenissa, Amyntaio, Rapsani, Trikomo, Siatista, Velventos, and, on a lesser scale, on Mount Athos, at Ossa, Ioannina, Magnesia, Kastoria and Trikala.

The Naousa Protected Designation of Origin (PDO) was established in 1971 and mandates the use of 100% Xinomavro grapes.

[5] In Goumenissa the grape is often blended with Negoska to produce very fruity wines with high alcohol levels.

[6] In recent years, artificial aging of red xinomavro wines has been a topic of research for several purposes.
