Martin Riese is a water sommelier, which, despite what your brain might be telling you right now, is a real thing. Riese is perhaps the most well known of a very small pool of water sommeliers around the world who have made a profession of tasting, analyzing, judging, and ultimately spreading the good word about the many different flavors of water our tastebuds have been missing out on. For this film, we followed Martin from his home at the Patina Restaurant in Los Angeles to the first of its kind water competition and trade show in Guangzhou, China. Why? “Because water is not just water.”
