Jurançon Blanc is a near-extinct white wine grape variety from Gascony. Even at its peak the variety was never widely grown, but by the turn of the 21st Century it was planted in only a few tiny pockets of vineyard in South West France.
Despite its name, Jurançon Blanc is not grown in Jurançon, and it is not a color mutation of Jurançon Noir. (DNA studies have suggested it is a natural cross of Folle Blanche and the obscure variety Pruéras. The potential is there to confuse the variety with a white wine from the Jurançon region.
Synonyms include: Brachetto Bianco, Notre Dame, Quillard, Sans-Pareil, Secal.
