Powerade's Island Burst is the complex and tropical flavor that won our hearts. We based the rankings on criteria like sweetness, taste, and how refreshing each drink was. We were looking for a sports drink with a balanced sweetness and a flavor true to the fruits it tries to mimic. "Island Burst" doesn't outright tell you the different fruit flavors contained within, but after one sip, you could taste each tropical fruit. The first that hit our tastebuds was pineapple, followed by a bright citrusy orange and a sweet, mellow mango. At the finish we picked up caramelized notes of banana.
