Fortified wine is a wine to which a distilled spirit, usually a grape spirit such as brandy, has been added. The two most well-known varieties of fortified wines are port and sherry. Both of these are fortified with brandy and, like most wines, are named for their locations of origin. (Therefore, California can make a "Port-Style" wine, but it's not actually Port unless it comes from Portugal!) Fortified wine can be sweet or dry, and is most notably characterized by its higher alcohol content.
