Ampelographers consider Prié blanc one of the oldest grape varieties in the Valle d'Aosta. Through a complex pedigree it appears to have some genetic relationship with most every other grape variety in the region. Recent DNA analysis has connected the grape to the Spanish wine grapes of Lairén in Andalusia and Albillo in Ribera del Duero and province of Ávila, but it is not yet known if the grape originated in Spain and traveled to Italy or the inverse.[1]
