The white grape variety originates from Italy. Synonyms are Austera, Guarnaccia, Varnaccia, Vernaccia, Vernazza, Vernazza Veronese and White Vernatsch. It is one of the many varieties with Vernaccia in its name. Nothing is known about the ancestry (parentage) or possible genetic connections. It used to be cultivated in Trentino, but is no longer important. No stocks were reported in 2016 (Kym Anderson statistics).
As honorary chairman of the Domäne Wachau, it is the easiest and quickest way for me to access the wein.plus encyclopaedia when I have questions. The certainty of receiving well-founded and up-to-date information here makes it an indispensable guide.
