What characteristic defines the wine Marsala?

Marsala is defined primarily by its fortified nature, which involves the addition of distilled spirits during the fermentation process. This practice not only increases the alcohol content of the wine but also helps preserve it, giving Marsala an extended shelf life and a unique profile compared to other wines. The fortification process contributes to its distinctive flavors and aromas, which can range from rich and sweet to dry, depending on the specific style of Marsala being produced.

While Marsala can indeed exhibit a sweet aroma and may have a dry finish in some variations, these characteristics are not as defining as its method of production. High acidity can be present in various styles of Marsala, but again, it’s not a primary characteristic that defines the wine overall. Fortification stands out as the key attribute that sets Marsala apart and makes it a unique class of wine.
