The white grape variety originates from Italy. It should not be confused with one of the many varieties with the Bonarda part of the name. According to DNA analyses carried out in 2013, it originates from a presumably natural cross between Triumphtraube x Schiava Grossa. However, this is based on only 20 DNA markers (see Molecular genetics). No stocks were reported in 2016 (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".
