The white grape variety originates from France. Synonyms are Brachetto Bianco, Braquet, Braquet Blanc, Dame Blanc, Dame Blanche, Jurançon, Notre Dame, Plant de Dame, Plant de Dame Blanc, Plant Debout, Plant Dressé, Quillard, Quillat and Secal. It is not a mutation of the red variety Jurançon Noir. According to DNA analyses carried out in 2013, it comes from a presumably natural cross between Folle Blanche x Prúeras. The medium-ripening vine is particularly susceptible to downy mildew and botrytis. It produces white wines of simple quality that are used for the distillation of Armagnac and Cognac. It is not allowed in the white wines of Jurançon. It was a crossing partner of the new Select variety. At the end of the 1950s, the variety still occupied almost 6,000 hectares of vineyards in south-west France, but is now threatened with extinction. For in 2016, only two hectares of vineyards were reported (Kym Anderson statistics).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
