History

In 1767 Englishman Joseph Priestley invented carbonated water when he first discovered a method of infusing water with carbon dioxide when he suspended a bowl of water above a beer vat at a local brewery in Leeds, England.[6] 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 entitled 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.[7]

In 1771 Swedish chemistry professor Torbern Bergman independently invented a similar process to make carbonated water. In poor health at the time yet frugal, he was trying to reproduce naturally-effervescent spring waters thought at the time to be beneficial to health.[citation needed]

Carbonated water was introduced in the latter part of the 18th century, and reached Kolkata (formerly known as Calcutta), India in 1822.

In the late eighteenth century, J. J. Schweppe (1740–1821), a German-born naturalised Swiss watchmaker and amateur scientist developed a process to manufacture carbonated mineral water, based on the process discovered by Joseph Priestley, founding the Schweppes Company in Geneva in 1783. In 1792 he moved to London to develop the business there.

The soda siphon, or syphon — a glass or metal pressure vessel with a release valve and spout for dispensing pressurised soda water — was a common sight in bars and in early- to mid-20th century homes where it became a symbol of middle-class affluence.

Ányos Jedlik (1800–95), a Hungarian, invented consumable soda-water that continues to be a popular drink today. He also built an early carbonated water factory in Budapest, Hungary.[citation needed] However, the process he developed at his factory for getting the CO2 into the water remains a mystery to this day. After this invention, a Hungarian drink made of wine and soda water called "fröccs" (wine spritzers) was spread throughout several countries in Europe.

Since then, carbonated water is made by passing pressurized carbon dioxide through 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 the gas to come out of the solution, thus forming the characteristic bubbles.
Social popularity, decline, and renaissance

Carbonated water changed the way people drank. Instead of drinking spirits neat, soda water, and later, carbonated soft drinks helped dilute alcohol, mitigating its harsh effects, and made having a drink more socially acceptable. Popping into a chum's house for hospitality from a "dash and a splash" - a whisky and soda - before going out to a social event was part of everyday activity in Britain as late as 1965.[citation needed] Whisky and sodas can be seen in many British TV series and films from the 1960s and earlier and the soda siphon is ubiquitous in many movies made before 1970. Social drinking would change with the counter-culture anti-establishment movement of the 1970s, and the decline of soda water would begin from that point. Soda water's 'last hurrah' in Britain may have been the popular 1970s product, 'Soda Stream' A commercially available home bottling kit, which enabled purchasers to combine fruit syrups, and water, to create sparkling beverages. The famous advertising tag-line 'Get Bizzy With The Fizzy' spawned a series of similar expressions, such as 'Get Buzzy With the Fuzzy'.

The popularity of soda water has declined since the late 1980s as drinking habits and fashions change and new bottled or canned beverages arrive, but soda-siphons are still bought by the more traditional bar trade and available at the bar in many upmarket establishments. In the UK there are now only two wholesalers of soda-water in traditional glass siphons, and an estimated market of around 120,000 siphons per year (2009). Worldwide, preferences are for beverages to be distributed in recyclable plastic containers which may, or may not, be recycled. The heavy glass needed for soda siphons is seen as environmentally unsustainable[citation needed] despite glass soda siphons being easily repaired and refilled by manufacturers.

Home soda siphons, and soda water are enjoying a renaissance in the 21st century as retro items become fashionable. Contemporary soda siphons are commonly made of aluminium, although glass and stainless steel siphons are available. The valve-heads of today are made of plastic, with metal valves, and replaceable o-ring seals. Older siphons are in demand on on-line auction sites. Carbonated water, without the acidity regulating addition of soda, is currently seen as fashionable although home production (see below) is mainly eschewed in favour of commercial products.
