What typically gives a Cosmopolitan its pink color?

The distinct pink color of a Cosmopolitan primarily comes from cranberry juice. This ingredient not only adds the characteristic hue to the cocktail but also contributes to its sweet and tart flavor profile. Cranberry juice is often used in cocktails for both taste and visual appeal, and in the case of the Cosmopolitan, it harmonizes well with vodka, triple sec, and lime juice, creating a balanced drink that is both refreshing and visually appealing.

Lemon juice and orange juice, while they can be used in cocktails, do not provide the pink coloration typical to a Cosmopolitan. Pineapple juice, similarly, is known for its yellow hue and tropical flavor, which does not align with the classic appearance of this cocktail. The use of cranberry juice is essential for achieving the signature look and taste of a Cosmopolitan.
