The white grape variety originates from France. Synonyms are Caca d'Oie, Cacabois, Cacabouet, Grosse Jacquère, Persan Blanc (but it is not a colour mutation of the red Persan variety), Saint-Péray and Saint-Péray Blanc. Despite seemingly suggestive synonyms, it must not be confused with the varieties Grosse Jacquère (no longer cultivated) or Molette. According to DNA analyses carried out in 2012, it is a presumably natural cross between Gouais Blanc x Grain. However, this is based on only 20 DNA markers (see molecular genetics). In addition, a parent-offspring relationship to the Italian variety Avanà (Hibou Noir in Savoie) was found. The medium to late maturing vine is susceptible to both powdery mildews. It is grown at the southern end of Lac du Bourget in Savoie. However, no stocks were recorded in 2016 (Kym Anderson statistics).
The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
