Martini Variations refer to the many different styles and flavors of the classic Martini cocktail. While the traditional Martini is made with gin and dry vermouth, variations can include different spirits, such as vodka, or flavored liqueurs. Ingredients like olives, lemon twists, or even fruit purees can be added to create unique tastes and presentations. Some popular variations include the Dirty Martini, which incorporates olive brine for a savory twist, and the Vesper Martini, made famous by James Bond in the novel "Casino Royale." Each variation offers a distinct experience while maintaining the essence of the original cocktail.
