Zinfandel (also known as Primitivo) is a variety of black-skinned wine grape genetically equivalent to the Croatian grapes Crljenak Kaštelanski and Tribidrag, as well as to the Primitivo variety traditionally grown in Apulia, Italy, The grapes typically produce a robust red wine, although, in the United States, a semi-sweet rosé wine called White Zinfandel has six times the sales of the red wine
