The Petite Sirah grape is grown mainly in California. This grape is thought to be related to either the Syrah grape or to the nearly-extinct Durif variety once grown in France's Rhone region. These wines are are big, deep-colored, and full-bodied wines with a peppery flavor. Although they are a fine stand-alone varietal, Petite Sirah grapes are often blended with Zinfandel to add complexity.
