Diolinoir is a red grape variety created in 1970 in Pully, Switzerland, at the Domaine du Caudoz by André Jaquinet, who also created Garanoir. Diolinoir is a cross between Robin Noir and Pinot Noir. The name Diolinoir comes from the name of its parents.
Diolinoir gives very colored wines with marked tannins and black fruit aromas. It is often used in blending, although it is increasingly found in single-variety wines. (https://sui-wineimports.com/grape-varieties/?age-verified=74a22e31a4)
