Carbonated water is drinking water enriched with carbon dioxide under pressure. In Czechia, the term sodovka is used for both commercially produced carbonated water and water prepared in home carbonation machines.
History
Industrial production of carbonated water began in the late 18th century. It became widespread in Czechia in the 19th century and became a staple non-alcoholic refreshment. Bottles were filled at soda-water plants and delivered to inns, cafés, and homes. Bottles with a glass marble as a stopper were typical.
Production
Water is infused with carbon dioxide (CO₂) under pressure. Commercial products contain approximately 3–5 g of CO₂ per liter. Home carbonation machines, such as SodaStream, work on the same principle: CO₂ from a pressurized cylinder is injected into a bottle of water.
Uses
Carbonated water is drunk on its own as a refreshing beverage. It is widely used for dilution: mixed with wine, it makes a wine spritzer, while mixed with syrup, it makes homemade lemonade. In cocktails, it can be used in place of tonic water or ginger beer. In cooking, it is added to pancake or griddle-cake batter, where the gas helps aerate the mixture.
Did you know? The Czech term “sodovka” comes from the English soda water. Sodium bicarbonate (baking soda), which released bubbles in water, was originally used for carbonation.
