Why does water taste different depending on the brand?
In: Chemistry
If you’ve ever tasted distilled water, it tastes “funny”, kind of flat.
The flavor of water mostly comes from dissolved minerals and gases in the water. Bottled municipal water may have some filtration/treatment/sterilization at the bottling plant, but it will most likely taste like whatever the local municipal water tastes like. Fancier brands will be from springs, or wells that have a unique mineral composition, and possibly natural or added carbon dioxide. The CO2 creates carbonic acid which gives it a slightly sour taste.
Others will treat the water through distillation and/or reverse osmosis and then add minerals to give it a desired flavor profile.
