A varietal found throughout the southern extremes of Italy, especially in Apulia, the heel of Italy's boot. Primitivo is known for producing hardy and full wines that are heavy with flavor and alcohol and sometimes sugar from the raisiny character of the grapes. There has been many DNA tests that have confirmed Primitivo's relation to Zinfandel, as they are both clones of the Croatian Crljenak varietal, but they are not the same. When grown next to each other in the vineyard they produce differing leaves, shoots and wines. They are close enough, however, that the U.S. Alcohol, Tobacco and Firearms agency is considering allowing Italian Primitivo to be sold in the U.S. as Zinfandel. Primitivo is known for rustic wines full of spice, black fruits and character.
