The white grape variety originates from Italy; it is one of the many varieties of the large Trebbiano name group. Synonyms are Greco Bianco 1, Trebbiano della Fiamma, Trebbiano di Romagna and Trebbiano Romagnolo Bijeli. The parentage is unknown. It must not be confused with the varieties Trebbiano Modenese or Verdicchio Bianco (Trebbiano di Lugana, Trebbiano di Soave), despite seemingly suggestive synonyms or morphological similarities. The early to medium ripening, high-yielding vine is susceptible to various fungal diseases except powdery mildew. It produces straw-coloured, neutral white wines with fresh acidity, which are also suitable for the production of distillates. This very old variety was already mentioned in 1303 by Petrus de Crescentiis (1230-1320) in the province of Ravenna.
