The Diolinoir vine was created around 1970 by André Jaquinet in Pully in the Swiss canton of Lausanne, crossing the Rouge de Doilly (also known as Robin noir) with Pinot Noir, in order to obtain a structured and intense colored wine, act to improve blacks blends of Swiss wines. In Italy it is an authorized vine in the Valle d'Aosta region. The berry is black, small, and spherical with blue-black colored skin. The bunch is medium, elongated, and tight with a small, pentagonal, five-lobed leaf. The Diolinoir variety has medium maturation period and medium vigor. The Diolinoir vine gives an intense ruby red, full-bodied wine, rich in tannins. It is generally used in blends with other varieties.
