What type of juice is used in a Grande Cool Lime Refresher?

The Grande Cool Lime Refresher features lime juice as one of its key ingredients, contributing to the beverage's signature tartness and refreshing flavor profile. This juice is essential in creating the drink's vibrant and zesty taste, which is meant to evoke a sense of freshness and rejuvenation. The Cool Lime Refresher is designed to be light and invigorating, making the lime juice a fitting choice to enhance this characteristic. Other fruit juices, like those from strawberries, berries, or peaches, would provide different flavor experiences that do not align with the refreshing lime-focused taste that Starbucks aims to achieve in this particular drink.
