What is a common mixer used in cocktails containing vodka?

Cranberry juice is a widely used mixer in cocktails that contain vodka, most notably in the popular drink known as the Vodka Cranberry. The tartness of cranberry juice complements the neutral flavor of vodka, creating a balanced and refreshing beverage. Additionally, cranberry juice adds a vibrant color and pleasant sweetness that enhances the overall drinking experience.

While other options may also serve as mixers for vodka cocktails, cranberry juice's specific flavor profile and popularity make it a standout choice. Sweet vermouth, for example, is often used in different contexts, primarily in cocktails like martinis. Club soda adds fizz and dilution but doesn't provide additional flavor as cranberry juice does. Sour mix, a combination of lemon and lime juice, could be used but is less common than cranberry juice in vodka-based cocktails.
