Although the name literally means "black Riesling," this variety is not at all related to the Riesling, but rather, it is an earlier-ripening mutation of the Spätburgunder (Pinot Noir).
A promising, and relatively new, red wine grape, Domina is a crossing of Portugieser and Spätburgunder that was bred at the Institute for Vine Breeding in Siebeldingen in the Pfalz.
