Carbonated water, also known as sparkling water, is water that has been infused with carbon dioxide gas under pressure. This process creates bubbles, giving the water a fizzy texture. It can be enjoyed plain or flavored with natural fruit essences, making it a popular alternative to sugary soft drinks. There are different types of carbonated water, including seltzer, club soda, and tonic water. Seltzer is simply carbonated water without added minerals, while club soda contains added minerals for taste. Tonic water, on the other hand, includes sweeteners and flavorings, often used in cocktails.
