Balzac blanc

Balzac blanc is a white French wine grape variety that is grown in the Charente and Charente-Maritime regions of Southwest France where it was once used for Cognac production but now is nearly extinct. The grape was one thought to be a color mutation of Mourvèdre (known as Monastrell and Balzac noir) but DNA analysis in 2000 showed that the two grapes were distinct and that Balzac blanc was a crossing of Gouais blanc and Chenin blanc.
