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 DOC status is equivalent to PDO: most countries limit the use of the term Marsala to those wines that come from the Marsala area, to which the European Union grants Protected Designation of Origin (PDO) status.
While the city's natives sometimes drink "vintage" Marsala, the wine produced for export is universally fortified similar to Port, Madeira and Sherry. Originally, this addition of alcohol was to ensure that it would last on long ocean voyages, but now it is made that way because of its popularity in foreign markets.
The most credible version of the introduction of Marsala fortified wine to a wider range of consumers is attributed to the English trader John Woodhouse. In 1773, Woodhouse landed at the port of Marsala and discovered the local wine produced in the region, which was aged in wooden casks and tasted similar to Spanish and Portuguese fortified wines then popular in England. Fortified Marsala was, and is, made using a process called in perpetuum, which is similar to the solera system used to produce Sherry in Jerez, Spain.
Woodhouse recognized that the in perpetuum process raised the alcohol level and alcoholic taste of this wine while also preserving these characteristics during long distance sea travel. Woodhouse further believed that fortified Marsala would be popular in England. Marsala indeed proved so successful that Woodhouse returned to Sicily and, in 1796, began its mass production and commercialization. In 1806, it was Benjamin Ingham (1784–1861), arriving in Sicily from Leeds, who opened new markets for Marsala in Europe and the Americas.
