Olives, often green or black, are a versatile ingredient used in various culinary contexts, including cocktails. Their briny and slightly tangy flavor can enhance the overall taste profile of a drink. Commonly, green olives are used in cocktails like the classic Martini, where they not only contribute to the aesthetic presentation but also add a savory note that complements the spirit's botanicals.

When used in cocktails, olives can be stuffed with ingredients such as pimentos, almonds, or even blue cheese, adding an extra layer of flavor and texture. These variations can cater to different palate preferences and elevate the drinking experience. The infusion of olive brine, known as "dirty" style, into cocktails like the Dirty Martini, introduces a salty, umami complexity that many cocktail enthusiasts appreciate.
