Origin: Southwest France
History: Jurançon Blanc is a near-extinct white wine grape variety from Gascony, Southwest France. Even at its peak, the variety was never widely grown, and by the turn of the 21st century, it was planted in only a few tiny pockets of vineyard in Southwest France. Despite its name, Jurançon Blanc is not grown in the Jurançon region, 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.
Appearance: Medium-sized clusters of pale green grapes.
Growing Traits: Jurançon Blanc has moderate vigor and an erect growth habit, allowing for short pruning. It is very susceptible to downy mildew and gray rot, requiring careful vineyard management. The grape ripens mid-season, about three and a half weeks after Chasselas.
