Gin Cocktails are a popular type of alcoholic beverage, most notably the Martini. The Martini is a classic cocktail made with gin, vermouth, and sometimes a garnish such as an olive or a lemon twist. It is typically served in a chilled glass and can be enjoyed straight up or on the rocks. Other popular gin cocktails include the Gin Fizz, the Tom Collins, and the Negroni. Gin cocktails are often enjoyed as aperitifs before a meal or as a nightcap after dinner.
