Sweet vermouth is a fortified wine flavored with various botanicals, including herbs, spices, and roots. It typically has a rich, sweet taste and a deep amber color. Sweet vermouth is often used in cocktails, such as the classic Manhattan and Negroni, adding complexity and depth to the drinks. Originating in Italy, sweet vermouth is made by infusing a base of white wine with a blend of aromatic ingredients. The process includes sweetening the wine with sugar or caramel, which enhances its flavor profile. It can also be enjoyed on its own, served over ice or with a twist of citrus.
