Dessert wine is a type of sweet wine that is typically served with dessert. It can come in a variety of styles, including fortified (e.g. Port), sparkling (e.g. Moscato d'Asti), and sticky or luscious (e.g. Sauternes). The style of dessert wine is determined by the grape variety used, the winemaking process, and the level of residual sugar in the wine. Dessert wines are typically higher in alcohol content than other wine styles.
