The white grape variety comes from Italy. Synonyms are Bianchetta Montecchiese, Greco delle Marche, Greco Maceratino, Maceratese, Matelicano, Montecchiese, Ribona, Uva Stretta, Verdicchio Marino and Verdicchio Tirolese. According to DNA analyses, there is no relationship with the varieties Grechetto di Orvieto, Greco, Greco Bianco and Trebbiano Toscano, although some synonyms seem to suggest that this is the case. However, there is a close relationship with the Verdicchio Bianco variety. This medium to late-maturing, high-yielding vine produces acidic wines of straw-yellow colour with an almond aroma. It is cultivated in the Marche region in the provinces of Ancona, Ascoli and Macerata. Among other things, it is authorised in the DOC wine Colli Maceratesi. In 2010, the area under cultivation was 177 hectares, with an upward trend (Kym Anderson).
