Technically, both sparkling water and carbonated water refer to water infused with carbon dioxide gas under pressure. That’s it. The bubbles you love are the result of CO2 dissolving into H2O, creating that signature tickle on your tongue.
So why the different names? Mostly marketing and mineral content. In the beverage world, “sparkling water” often implies a natural source—like Perrier or San Pellegrino—where the bubbles come from a spring. “Carbonated water” is usually the generic term for any fizzy H2O, whether from a tap or a bottle.
The only real chemical difference? Natural sparkling waters contain minerals like calcium, magnesium, and potassium that give them a distinct mouthfeel and subtle flavor. Artificially carbonated waters are simply pure water with CO2 added—neutral and crisp.
