What it is

Carbonated water is simply water that has been infused with carbon dioxide gas under pressure. This process creates the familiar bubbles and slight acidity found in sparkling water. It is made by dissolving carbon dioxide into purified water, often through a mechanical process.

Why it's used

Carbonated water is primarily used as a beverage base, providing a refreshing mouthfeel and a neutral flavor profile. It is the main ingredient in sparkling water, seltzer, and club soda. Manufacturers also use it as a mixer for alcoholic and non-alcoholic drinks.

Health notes

Carbonated water is generally recognized as safe (GRAS) by the FDA for use in food. It contains no calories, sugar, or artificial sweeteners unless added. Some studies suggest that carbonation may affect appetite hormones, but the evidence is mixed and more research is needed. JECFA has evaluated carbonated water and found no safety concerns.

Allergen info

Carbonated water is not derived from any of the major allergens and does not contain gluten.
