What is the standard garnish for a Dirty Martini?

The standard garnish for a Dirty Martini is typically one olive, which adds a classic touch to this cocktail. The term "dirty" refers to the inclusion of olive brine in the drink, which gives it a distinct flavor and a slightly cloudy appearance. While some martini enthusiasts may prefer additional olives for garnish, the traditional serving generally includes just one to complement the drink without overwhelming it.

Choosing several olives or a lemon twist does not align with the traditional presentation of a Dirty Martini. Instead, the single olive enhances the drink's character while keeping the focus on the unique salty flavor profile contributed by the olive brine.
