The white grape variety comes from Italy. Synonyms are Spargoletta Bianca, Spergolà, Spergolina and Spergolinàis. It should not be confused with Sauvignon Blanc or Sémillon, despite the fact that they seem to be synonyms or morphological similarities (Spergola was even an official synonym for Sauvignon Blanc in Italy in the past). The originality was confirmed by DNA analyses carried out in 2001. This also revealed a close genetic relationship to the variety Pignoletto. According to personal information from Dr. Erika Maul(Julius Kühn Institute), the Vernaccia di Oristano variety is identical.
The variety was first mentioned in 1811 under Spergolina. It was one of the most important varieties in Emilia-Romagna in the 19th century. The medium-ripening vine produces acid-rich white wines, which are well suited to sparkling wine production. It is, for example, permitted in the DOC wine Colli di Scandiano e di Canossa. In 2010, 110 hectares of vineyards were designated in Italy (Kym Anderson).
