Xinomavro (Greek: Ξινόμαυρο, English translation: "sour black") is the principal red wine grape of the uplands of Naousa in the regional unit of Imathia, and around Amyntaio, in Northern Greece. Various writers have compared Xinomavro to Bordeaux, Burgundy, and Barolo. 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.
