This red grape variety is a new cross between Gamay x Reichensteiner. Synonyms are B-28, Gastar, Granoir and Pully B-28. The cross was made in Switzerland in 1970 by André Jaquinet at the Federal Research Station Changins near Nyon (Vaud, Switzerland). It was first called Gastar and then Granoir before receiving its final name. Plant variety protection was granted in 1990. The same parents also gave rise to the two new varieties Gamaret and Mara. The early-maturing vine is resistant to botrytis. It produces colourful, fruity red wines with a blackberry aroma. In Switzerland, the variety is cultivated on 225 hectares in the cantons of Geneva, Vaud and Valais. There are also small populations in Germany, Savoie-France (0.2 ha) and in the Italian region of Puglia (4 ha). In 2016, a total of 229 hectares of vines were reported (Kym Anderson statistics).
