Petit Rouge

The red grape variety originates from the border region Italy/Switzerland. Synonyms are Orion Gris, Oriou, Oriou Curare, Oriou Lombard, Oriou Petit Rouge, Oriou Picciou, Oriou Voirard, Picciou Rouge, Picciou Rouzo and Rouge du Valais. The Oriou synonyms are different varieties. It must not be confused with the Cornalin (Humagne Rouge) variety, despite the synonyms that seem to indicate it. It is one of the oldest and most widespread varieties in the Aosta Valley. The parentage is unknown. A presumed descent from Burgundy or a presumed cross between local variety x wild vine is unlikely from a genetic and morphological point of view. In Switzerland, the variety is counted among the Old Growths group of grape varieties. According to DNA analyses carried out in 2003, the variety Rouge du Pays (Cornalin du Valais) originates from a presumably natural cross between Petit Rouge x Mayolet. This late-ripening variety produces dark purple, spicy red wines with soft tannins and pronounced acidity and redcurrant aroma. It is the main ingredient in the DOC red wines Valle d'Aosta Chambave Rosso, Valle d'Aosta Enfer d'Arvier and Valle d'Aosta Torrette. In 2016, a total of 68 hectares of vines were reported, with a downward trend (Kym Anderson statistics).

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
