The term 'Dark Sweet Sherry' is a type of fortified wine made from white grapes grown near the town of Jerez de la Frontera in Andalusia, Spain. The most popular type of sherry is Amoroso, which is a sweet, dark, and full-bodied sherry with a rich, nutty flavor. It is aged for at least three years in oak barrels, giving it a deep amber color. Amoroso is often served as an aperitif or dessert wine.
