The white grape variety originates from Italy. Synonyms are Greco Bianco, Greco Bianco di Cirò, Greco del Cirotano, Guardavalle di Passuli, Montonico di Rogliano, Passulara, Uva da Passito, Uva Greca and Vardavalli. It must not be confused with the Greco, Greco Bianco or Mantonico Bianco varieties, despite the synonyms or morphological similarities that seem to indicate it. This late-ripening vine produces slightly astringent white wines with a nutty aroma. It is named after the town in the province of Catanzaro. The variety is mainly cultivated in the province of Reggio Calabria, Calabria, where it is allowed in the DOC wine Bivongi. In 2016, a total of 16 hectares were designated (Kym Anderson).
