The white grape variety originates from asd Italy; it occurs under different names in Corsica (France) and Sardinia (Italy). Synonyms are Brustiano, Brustianu, Calitrano, Calitranu, Colitrano, Licronaxiu and Licronaxu Bianco. The parentage (parenthood) is unknown. It must not be confused with the varieties Brustiano Faux, Retagliado Bianco or Vermentino, despite the fact that synonyms or morphological similarities seem to indicate it. DNA analyses carried out in 2007 showed that the Sardinian Licronaxu Bianco is identical, and Licronaxu Nero is a colour mutation. The high-yielding vine is susceptible to powdery mildew. In 2010 (neither under Brustiano nor Licronaxu) no stocks were reported (Kym Anderson).
