3. Bottled water
Bottled water won't be denied. As a trending beverage, it's owned the better-for-you space with its simple proposition: nothing. No calories, no additives, no sugars, no chemicals. Sure, that's changed a little with sparkling, flavors and other enhancements (caffeine, protein, vitamins and more) finding growth. But in general, the proposition remains the same: simple and effective. No wonder SodaStream, the home carbonated-soft-drink brewer, has refocused its marketing campaign to "water made exciting."
