Petit Rouge is a red Italian wine grape variety that ampelographers believe is indigenous to the Valle d'Aosta (French: Vallée d'Aoste) region of northwest Italy.[1] However, there is some confusion about whether Petit Rouge is the same variety as the red Swiss wine grape Rouge de Valais.[2]
The grape is somewhat obscure and is not widely grown outside the Valle d'Aosta where it is primarily a blending variety but some varietal wines are produced.[3] In blends, it adds floral aroma notes and dark color to the wines.[2]
