What does the term "vermouth" refer to?

The term "vermouth" refers specifically to a fortified wine that has been flavored with various botanicals, including herbs, spices, and other natural flavorings. This unique preparation gives vermouth its distinct taste profile, which can range from sweet to dry, depending on the variety. Vermouth is often used as a key ingredient in many cocktails, such as martinis and manhattans, showcasing its significance in mixology.

Understanding the definition of vermouth is essential for bartenders as it not only helps in crafting classic cocktails but also in performing substitutions or creating innovative drinks. The other options do not accurately describe vermouth, as they pertain to different types of spirits or cocktail components. For example, vermouth is not a type of gin, a brand of vodka, or a cocktail garnish. This clarity in definition is crucial for those studying bartending and cocktail preparation.
