Prié blanc is a white Italian wine grape variety that is grown almost exclusively in the Valle d'Aosta DOC of northwest Italy. The Valle d'Aosta varietal wine Blanc de Morgex et de La Salle is made from Prié blanc grapes. 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.〔J. Robinson, J. Harding and J. Vouillamoz ''Wine Grapes – A complete guide to 1,368 vine varieties, including their origins and flavours'' pgs 845–848 Allen Lane 2012 ISBN 978-1-846-14446-2〕 ==History== Ampelographers do not yet know definitively the origins of Prié blanc but evidence shows that it is a very old variety that has been growing in the Valle d'Aosta region of northwest Italy since at least 1691 when it was documented as one of the grapes growing in the commune of Saint-Pierre near the city of Aosta. The origins of the name ''Prié'' is unknown but one of the grape's early synonyms ''Blanc du Valdigne'' comes from the Latin name for the upper reaches of the Aosta Valley that extends to Mont Blanc with some ampelographers speculating that grape maybe indigenous to the foothills of the mountain.〔 Another synonym ''Agostena'' which maybe 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. However, the name could also be a derivative from the Italian word ''agosto'' referring to the month of August when this early ripening variety is sometimes ready to be harvested.〔Schneider A., Raimondi S., Torello Marinoni D. ( Prié blanc ) Italian Vitis Database, Accessed: January 9th, 2014 〕 Another potential place of origin for Prié blanc is the Valais region of Switzerland where the grape seems to have grandparent relationship to the Swiss wine grape Rouge du Pays through Prié blanc's offspring Mayolet. In Switzerland, one of Prié blanc's primary synonyms is ''Bernarde'' which maybe a reference to the Great St Bernard Pass connecting the Valle d'Aosta to Valais which would likely be the path that cuttings of the grapevine would spread from one region to the other. However, ampelographers like Swiss grape geneticist José Vouillamoz believe that it is far more likely that Prié blanc spread from Aosta to Switzerland than the other way around.〔 An Italian origin of Prié blanc was long assumed until DNA analysis in 2010 identified plantings of ''Legiruela'' in the province of Ávila in north central Spain were actually Prié blanc. 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. Additionally, the exact relationship between Prié blanc, Lairén and Albillo is not yet fully known as to which grape variety is the parent and which varieties are the offspring, suggesting that potentially Prié blanc could be of Spanish origins.〔 Another grape variety that Prié blanc has an unclear parent-offspring relationship with is the Piedmont wine and table grape Luglienga, of which the two varieties are often confused with.〔 As Luglienga has been growing in the Piedmont region since at least 1329 (although its name has changed) (more than 300 years before the first recorded mention of Prié blanc), it would strongly suggest that Luglienga is more likely the parent variety with Prié blanc the offspring. But the question of how Prié blanc traveled from northern Italy to Spain is still not answered.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prié blanc」の詳細全文を読む スポンサード リンク
