Carbonation

In everyday use, carbonation means the carbon dioxide (CO2) dissolved in a drink. It provides the tingle on the tongue, the bubbles in the glass and a slightly sour impression of freshness. When a bottle is opened, gas escapes because the pressure drops.

Carbonation can come naturally from the spring or be added to the drink. The content is stated in grams per litre and ranges from still to strongly sparkling. Less gas dissolves in warm water, which is why cool drinks stay bubbly longer. Too much carbonation can cause a feeling of fullness for some people. In a drink it also protects against oxygen and supports shelf life.
