Water containing dissolved carbon dioxide gas

Carbonated water (also known as soda water, bubbly water, sparkling water, fizzy water, club soda, water with gas, in many places as mineral water, or especially in the United States as seltzer or seltzer water) is water containing dissolved carbon dioxide gas, either artificially injected under pressure or occurring due to natural geological processes. Carbonation causes small bubbles to form, giving the water an effervescent quality. Common forms include sparkling natural mineral water, club soda, and commercially produced sparkling water. Club soda and sparkling mineral water and some other sparkling waters contain added or dissolved minerals such as potassium bicarbonate, sodium bicarbonate, sodium citrate, or potassium sulfate. These occur naturally in some mineral waters but are also commonly added artificially to manufactured waters to mimic a natural flavor profile and offset the acidity of introducing carbon dioxide gas giving one a fizzy sensation. Various carbonated waters are sold in bottles and cans, with some also produced on demand by commercial carbonation systems in bars and restaurants, or made at home using a carbon dioxide cartridge. It is thought that the first person to aerate water with carbon dioxide was William Brownrigg in the 1740s. Joseph Priestley invented carbonated water, independently and by accident, in 1767 when he discovered a method of infusing water with carbon dioxide after having suspended a bowl of water above a beer vat at a brewery in Leeds, Yorkshire. Priestley's apparatus, almost identical to that used by Henry Cavendish five years earlier, which featured a bladder between the generator and the absorption tank to regulate the flow of carbon dioxide, was soon joined by a wide range of others. However, it was not until 1781 that carbonated water began being produced on a large scale with the establishment of companies specialized in producing artificial mineral water. While Priestley's discovery ultimately led to the creation of the soft drink industry—which began in 1783 when Johann Jacob Schweppe founded Schweppes to sell bottled soda water—he did not benefit financially from his invention.

Natural and manufactured carbonated waters may contain a small amount of sodium chloride, sodium citrate, sodium bicarbonate, potassium bicarbonate, potassium citrate, potassium sulfate, or disodium phosphate, depending on the product. These occur naturally in mineral waters but are added artificially to commercially produced waters to mimic a natural flavor profile and offset the acidity of introducing carbon dioxide gas (which creates low 5 6 pH carbonic acid solution when dissolved in water). Artesian wells in such places as Mihalkovo in the Bulgarian Rhodope Mountains, Medžitlija in North Macedonia, and most notably in Selters in the German Taunus mountains, produce naturally effervescent mineral waters.

By itself, carbonated water appears to have little to no impact on health. Carbonated water such as club soda or sparkling water is defined in US law as a food of minimal nutritional value, even if minerals, vitamins, or artificial sweeteners have been added to it. Carbonated water does not appear to have an effect on gastroesophageal reflux disease. There is tentative evidence that carbonated water may help with constipation among people who have had a stroke.

While carbonated water is somewhat acidic, this acidity can be partially neutralized by saliva. A study found that sparkling mineral water is slightly more erosive to teeth than non carbonated water but is about 1% as corrosive as soft drinks are. A 2017 study by the American Dental Association showed that it would take over 100 years of daily sparkling water consumption to cause damage to human teeth⁠a claim that could not apply if there is added sugar or artificial flavorings, which often include citric acid and other fruit acids, predicted to have an impact on human teeth.

Many alcoholic drinks, such as beer, champagne, cider, and spritzer, were naturally carbonated through the fermentation process for centuries. In 1662 Christopher Merret created 'sparkling wine'. William Brownrigg was apparently the first to produce artificial carbonated water, in the early 1740s, by using carbon dioxide taken from mines. In 1750 the Frenchman Gabriel François Venel also produced artificial carbonated water, though he misunderstood the nature of the gas that caused the carbonation. In 1764, Irish chemist Dr. Macbride infused water with carbon dioxide as part of a series of experiments on fermentation and putrefaction. In 1766 Henry Cavendish devised an aerating apparatus that would inspire Joseph Priestley to carry out his own experiments with regard to carbonated waters. Cavendish was also aware of Brownrigg's observations at this time and published a paper on his own experiments on a nearby source of mineral water at the beginning of January in the next year. In 1767 Priestley discovered a method of infusing water with carbon dioxide by pouring water back and forth above a beer vat at a local brewery in Leeds, England. The air blanketing the fermenting beer—called 'fixed air'—was known to kill mice suspended in it. Priestley found water thus treated had a pleasant taste, and he offered it to friends as a cool, refreshing drink. In 1772, Priestley published a paper titled Impregnating Water with Fixed Air in which he describes dripping "oil of vitriol" (sulfuric acid) onto chalk to produce carbon dioxide gas, and encouraging the gas to dissolve into an agitated bowl of water. Priestley referred to his invention of this treated water as being his "happiest" discovery. Priestley's apparatus, which was very similar to that invented by Henry Cavendish five years earlier, featured a bladder between the generator and the absorption tank to regulate the flow of carbon dioxide, and was soon joined by a wide range of others, but it was not until 1781 that carbonated water began being produced on a large scale with the establishment of companies specialized in producing artificial mineral water. In 1792 he moved to London to develop the business there. In 1799 Augustine Thwaites founded Thwaites' Soda Water in Dublin. A London Globe article claims that this company was the first to patent and sell "Soda Water" under that name. The article says that in the hot summer of 1777 in London "aerated waters" (that is, carbonated) were selling well but there was as yet no mention of "soda water", though the first effervescent drinks were probably made using "soda powders" containing bicarbonate of soda and tartaric acid. The name soda water arose from the fact that soda (sodium carbonate or bicarbonate) was often added to adjust the taste and pH. Modern carbonated water is made by injecting pressurized carbon dioxide into water. The pressure increases the solubility and allows more carbon dioxide to dissolve than would be possible under standard atmospheric pressure. When the bottle is opened, the pressure is released, allowing gas to exit the solution, forming the characteristic bubbles. Modern sources of CO2 are from industrial processes, such as burning of fossil fuels like coal and methane at power plants, or steam reforming of methane for hydrogen production.

In the United States, plain carbonated water was generally known either as soda water, due to the sodium salts it contained, or seltzer water, deriving from the German town Selters renowned for its mineral springs. Sodium salts were added to plain water both as flavoring (to mimic famed mineral waters, such as naturally effervescent Selters, Vichy water and Saratoga water) and acidity regulators (to offset the acidic 5 6 pH carbonic acid created when carbon dioxide is dissolved in water). In the 1970s marketing driven terms such as sparkling water gained favor, with an explosion of consumption of the naturally carbonated Perrier water
Generally, seltzer water has no added sodium salts, while club soda still retains some sodium salts.

In 1872, soft drink maker Hiram Codd of Camberwell, London, designed and patented the Codd neck bottle, designed specifically for carbonated drinks. The Codd neck bottle encloses a marble and a rubber washer/gasket in the neck. The bottles were filled upside down, and pressure of the gas in the bottle forced the marble against the washer, sealing in the carbonation. The bottle was pinched into a special shape to provide a chamber into which the marble was pushed to open the bottle. This prevented the marble from blocking the neck as the drink was poured. Soon after its introduction, the bottle became extremely popular with the soft drink and brewing industries mainly in the UK and the rest of Europe, Asia, and Australasia, though some alcohol drinkers disdained the use of the bottle. R. White's, the biggest soft drinks company in London and south east England when the bottle was introduced, was among the companies that sold their drinks in Codd's glass bottles. One etymology of the term codswallop originates from beer sold in Codd bottles, though this is generally dismissed as a folk etymology. The bottles were produced for many decades, but gradually declined in usage. Since children smashed the bottles to retrieve the marbles, vintage bottles are relatively rare and have become collector items, particularly in the UK. Due to the risk of explosion and injuries from fragmented glass pieces, use of this type of bottle is discouraged in most countries, since other methods of sealing pressurized bottles can more easily incorporate release of unsafe pressures. The Codd neck design is still used for the Japanese soft drink Ramune, and in the Indian drink called Banta.

Soda makers or soda carbonators, known as countertop carborators, are appliances that carbonate water with multiple use carbon dioxide canisters. Soda makers may reach a higher level of carbonation than home soda siphons. A variety of systems are produced by manufacturers and hobbyists. The commercial units may be sold with concentrated syrup for making flavored soft drinks. One major producer of soda carbonators is SodaStream. Their products were popular during the 1970s and 1980s in the United Kingdom, and are associated with nostalgia for that period and have experienced a comeback in the 2000s.

The process of dissolving carbon dioxide in water is called carbonation. Commercial soda water in siphons is made by chilling filtered plain water to or below, optionally adding a sodium or potassium based alkaline compound such as sodium bicarbonate to neutralize the acid created when pressurizing the water with carbon dioxide (which creates high 8 10 pH carbonic acid bicarbonate buffer solution when dissolved in water). The gas dissolves in the water, and a top off fill of carbon dioxide is added to pressurize the siphon to approximately , some higher than is present in fermenting champagne bottles. In many modern restaurants and bars soda water is manufactured on site using devices known as carbonators. Carbonators use mechanical pumps to pump water into a pressurized chamber where it is combined with carbon dioxide from pressurized tanks at approximately The pressurized carbonated water then flows either directly to taps or mixing heads where flavoring is added before dispensing.

Carbonated water is a key ingredient in soft drinks, beverages that typically consist of carbonated water, a sweetener, and a flavoring such as cola, ginger, or citrus. Plain carbonated water or sparkling mineral water is often consumed as an alternative to soft drinks. Club soda is carbonated water to which compounds such as sodium bicarbonate or potassium sulfate have been added. Many manufacturers produce unsweetened sparkling water products that are lightly flavored by the addition of aromatic ingredients such as essential oils. Carbonated water is often mixed with fruit juice to make sparkling alcoholic and non alcoholic punches.

Carbonated water is a diluent mixed with alcoholic beverages where it is used to top off the drink and provides a degree of 'fizz'. Adding soda water to "short" drinks such as spirits dilutes them and makes them "long" (not to be confused with long drinks such as those made with vermouth). Carbonated water also works well in short drinks made with whiskey, brandy, and Campari. Soda water may be used to dilute drinks based on cordials such as orange squash. Soda water is a necessary ingredient in many cocktails, such as whiskey and soda or Campari and soda.

Carbonated water is increasingly popular in Western cooking as a substitute for plain water in deep frying batters to provide a lighter texture to doughs similar to tempura. Kevin Ryan, a food scientist at the University of Illinois at Urbana–Champaign, says the effervescent bubbles when mixed with dough provide a light tempura like texture, which gives the illusion of being lower calorie than regular frying batters. The lightness is caused by pockets of carbon dioxide gas being introduced into the batter (a process which natural rising using yeast also creates) and further expanding when cooked.

Since the dissolved gas in carbonated water acts as a temporary surfactant, it has been recommended as a household remedy for removing stains, particularly those of red wine.
