A Dirty Martini is a popular cocktail that combines gin or vodka with dry vermouth and olive brine. The addition of olive brine gives the drink its distinctive salty flavor, setting it apart from a traditional martini. It is typically garnished with olives, enhancing its savory profile. The drink is served chilled, often in a classic martini glass. Bartenders may adjust the amount of olive brine to suit individual preferences, making it either "dirtier" or lighter. The Dirty Martini is favored by those who enjoy a more robust and savory twist on the classic martini experience.
