Bia blanc (French pronunciation:[bjablɑ̃]) is a white French winegrape variety that is no longer commercially cultivated for wine production with only a few plantings existing worldwide in viticultural archives and experimental vineyards. The exact origins of Bia blanc are not yet known though ampelographers have noted that the grapevine shares some morphological similarities to the red Isère grape Peloursin, one of the parent varieties to Petite Sirah (Durif).[1]
