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.hile the city's natives sometimes drink vintage Marsala, the wine produced for export is universally fortified similar to Port, Madeira and Sherry.
Marsala is a fortified wine and I don't believe it will spoil, the taste diminish after a while but you can pretty much keep it indefinitely. I have an opened bottle that I use for cooking and its 6 months old and still good. lloreen is correct if it were vinegar but I assume you are talking about the wine.
