Diolinoir is a dark-skinned red grape indigenous to Switzerland, made by crossing between the Rouge de Diolly and Pinot Noir in 1970. The grape was bred by André Jacquinet at the Caudoz viticultural research centre in Pully and the name is a mixture of both crossing varietals. It is early to medium-ripening, high-yielding vine susceptible to trickling it has small berries and it is resistant to botrytis, giving colourful, tannin-rich red wines with blackberry aromas and long fruity aftertaste. It is very suitable for the Alpine climate. Diolinoir has a very dark colour and it is often used in blends to add colour as well as spicy and earthy notes. It is only planted in Switzerland in the regions of Valais, Vaud and Ticino.
