Which two juices are combined in a Seabreeze cocktail in equal parts?

In a Seabreeze cocktail, the two juices that are combined in equal parts are cranberry juice and grapefruit juice. This combination creates a refreshing drink that balances the tart, slightly sweet flavor of cranberry with the bitter notes of grapefruit. The result is a well-rounded cocktail that is not overly sweet, making it appealing to a wide range of tastes. This drink is particularly popular in warm weather due to its light and refreshing qualities.

The other juice combinations listed do not align with the traditional Seabreeze recipe, which specifically calls for cranberry and grapefruit to achieve its signature taste.
