Because of Cool Hunting's unusually high Juicy Water by Innocent Drinks. The health-focused U.K. company is taking aim at the shortcomings of most juice drinks: they're either packed with preservatives or simply far too sweet. Innocent's solution is to start with spring water (about 70% of the mix) and add only real fruit and a dash of sugar. The result is a light and delicious thirst-quencher that's hydrating and healthy. Though the drinks aren't yet available stateside, Britons can enjoy them in four flavors: black currant, cranberry-raspberry, lemon-lime, and mango-passion fruit.
