The white grape variety originates from Italy; it is one of the many varieties of the large Trebbiano name group. Synonyms are Greco di Velletri, Rossetto, Rossola, Trebbiano dei Castelli, Trebbiano di Spagna and Trebbiano Giallo di Velletri. It must not be confused with the Greco, Rossetto or Trebbiano Modenese varieties, despite seemingly suggestive synonyms or morphological or name similarities. The medium to late ripening vine is resistant to both types of powdery mildew. It is mainly cultivated in the Latium region, where it is used in the DOC/DOCG white wines Bianco Capena, Castelli Romani, Cerveteri, Colli Albani, Colli Etruschi Viterbesi, Colli Lanuvini, Colli della Sabina, Controguerra, Cori, Est! Est!!! Est!!! di Montefiascone, Frascati, Roma and Tarquinia is authorised. There are other stocks in Lombardy, where it is included in the DOC wine Garda Colli Mantovani, and Emilia-Romagna, where it is used for balsamic under the name Trebbiano di Spagna. In 2016, 2,275 hectares of vines were reported (Kym Anderson statistics).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
