Which type of Martini includes olive juice in its recipe?

The Dirty Martini is distinguished by its inclusion of olive juice in the recipe. This addition gives the cocktail a briny flavor that enhances the traditional combination of gin and dry vermouth typically found in a standard Martini. The olive juice not only adds flavor but also influences the overall color and presentation of the drink, often accompanied by an olive garnish itself.

In contrast, a Regular Martini is made without any mixtures, focusing purely on the gin and vermouth, while an Extra Dry Martini contains even less vermouth than a Regular Martini, emphasizing the spirit itself. The Perfect Martini seeks a balance by using equal parts dry and sweet vermouth, which does not include any olive juice. Thus, the unique characteristic of the Dirty Martini is what sets it apart, making it the right choice in this context.
