The red grape variety probably comes from Germany. According to DNA analyses carried out in 2016, it originates from a presumably natural cross between Savagnin(Traminer) x unknown partner. It was a parent of the varieties Affenthaler, Schwarzer Heunisch and Tauberschwarz. In 2010 no stocks were reported (Kym Anderson). Sweet black is also a synonym for Béclan, Blue Silvaner and Pinot Noir.
