Which mixer is primarily used in flavored martinis?

Flavored martinis are predominantly crafted using vodka as the base spirit. Vodka's neutral flavor profile allows other ingredients, such as flavored liqueurs, fruit purees, or syrups, to shine through without being overshadowed. This versatility makes vodka the mixer of choice for a wide range of flavored martini variations, such as appletinis, cosmopolitans, and other fruit-infused options.

While gin is also used in some martinis, its botanical flavors can clash with the intended taste of flavored martinis. Rum and pisco, although delicious in their own right, are also less common choices for these types of cocktails. Their distinct flavor profiles do not typically align with the goal of creating a bright, refreshing drink that showcases a particular flavor in the way vodka does. Hence, the choice of vodka as the primary mixer in flavored martinis is essential for maintaining a balanced and appealing flavor in the cocktail.
