What is the main ingredient in the Passion Tango beverage?

The main ingredient in the Passion Tango beverage is tea, specifically a blend of hibiscus, lemongrass, and apple. This herbal tea infusion gives the drink its distinctive flavor and refreshing taste. Passion Tango is caffeine-free, appealing to those who enjoy a herbal blend rather than a coffee or caffeinated option. While other choices like cocoa, coffee, and soda represent different beverage categories, they do not align with the composition of the Passion Tango, which focuses on the herbal tea base. The choice of tea as the primary ingredient helps create a unique and soothing beverage that stands out in Starbucks' menu offerings.
