Glacéau Smart water is inspired by clouds and the way mother nature makes water, known as the hydrologic cycle. Glaceau simulates this process by vapor distilling water, making every drop as pure as the very first drop of rain (before it passes through pollutants, of course). If that’s not smart enough, they then one-up mother nature by adding in electrolytes for a clean crisp taste. It sounds like genius because it is. Smart water is smart because it’s made that way.
