Cookbook:Carbonated Water

Carbonated water, soda water, fizzy water, sparkling water, or seltzer is water that contains bubbles of gas.

Characteristics
Commercial carbonated water is "charged" with carbon dioxide gas, which dissolves in the liquid under pressure. When the container is opened and poured, the gas bubbles out of the water and makes it fizzy. The combination of bubbles and increased acidity from the carbon dioxide causes a tingly sensation in the mouth when carbonated water is consumed.

A few different sub-types of carbonated water exist. Club soda usually has minerals and salts added to it for flavor. Sparkling mineral water may use water from a mineral spring, which naturally contains these flavor components.

Selection and storage
Carbonated water should be kept cold after opening, since the bubbles escape more quickly in warmer temperatures.

Use
Carbonated water can be drunk on its own instead of plain water, and it can also be used in various beverages. Sometimes carbonated water is used in cooking for its acidity and to help create lighter doughs and batters.
