Vermouth is a fortified wine that is flavored with various botanicals, herbs, and spices, creating a complex, aromatic profile. It is typically made from white or red wine, which is then fortified with a distilled spirit, such as brandy, and infused with flavors like wormwood, citrus peel, cinnamon, cloves, and others. Vermouth comes in two main varieties: dry (often used in classic cocktails like the Martini) and sweet (which is commonly used in cocktails like the Negroni). It can be enjoyed on its own, chilled or with a twist of citrus, or as a key ingredient in many mixed drinks.
