The red grapes (also Pully 4-42) is a new variety from Rouge de Diolly (Robin Black) x Pinot Noir. The crossing took place in 1970 by André Jaquinet at the Swiss Federal Research Station Changins in Pully (canton of Vaud, Switzerland). The high yielding variety is very resistant to rot. It provides a color-rich, well-structured tannin red wine, especially for blends such as the Valais wine brand Dole is used. It is grown in the cantons of Vaud, Valais and Ticino.
