Prié blanc

Prié blanc is a white Italian wine grape variety that is grown almost exclusively in the Valle d'Aosta DOC of northwest Italy.

[2] Another synonym Agostena which may be derived from the ancient Latin name for the city of Aosta, Augusta Praetoria, also hints to the grape's long history and potential origins in this region.

Further profiling connected the grape to several Spanish wine grape varieties including a parent-offspring relationship with Albillo from the Ribera del Duero, Ávila in Castile and León and Madrid and the Lairén grown in the southern Spanish wine region of Andalusia, indicating that Prié blanc must have been in Spain for a very long time in order to propagate and interact with other varieties grown so widely apart.

Most vines of Prié blanc are ungrafted due to phylloxera's difficulties surviving in the harsh climate conditions of the Valle d'Aosta.

[2] The vast majority of Prié blanc plantings in the world are found in the Valle d'Aosta region of northwest Italy with 39 hectares (96 acres) recorded in 2000.

[1][6][7][8] Outside of Italy, a scant 0.02 hectares (0.049 acres) of Prié blanc is planted in the Valais region of Switzerland as of 2005[9] where the grape is known as Bernarde.

[10] In Spain, plantings of the grape around found around the commune of San Esteban del Valle in the province of Ávila in the Castile and León region under the name Legiruela.
