Grown mainly in California, this red wine grape produces a big, robust and peppery wine. Although not as popular as California's cabernet sauvignon, pinot noir or zinfandel, Petite Sirah has a following among those who like big, full-bodied wines. The Petite Sirah grape is also used as a blending grape to give a little more zest and complexity to other red wines. This varietal is also spelled Petit Syrah and Petit Sirah.
