What soda has prune juice in it?

There is no commercially available soda that contains prune juice.

Prune juice is a sweet, tart beverage made from dried plums. While it's often used in baking and as a natural laxative, it's not a common ingredient in sodas.

If you're looking for a prune-flavored beverage, you might try a prune juice cocktail or a prune-based smoothie.
