Marsala is a wine, dry or sweet, produced in the region surrounding the Italian city of Marsala in Sicily. Marsala first received Denominazione di Origine Controllata (DOC) status in 1969.
The different grape varieties used to make Marsala give it different colors and flavors. It can be found as dry (secco), semisweet (semisecco) or sweet (dolce). Dry Marsala is mostly used in meat and vegetable dishes and for drinking. The sweeter Marsala wines are used mostly in desserts.
