What does carbonating mean?
"Carbonating" is the present participle of the verb "to carbonate," meaning to dissolve carbon dioxide gas in a liquid under pressure so that the liquid becomes effervescent. It is the process behind every glass of sparkling water, bottle of soda, and keg of draft beer: CO2 is injected into the chilled liquid, where it dissolves and later escapes as the familiar fizz and bite on the tongue. In home brewing, carbonating may happen naturally, with a measured amount of sugar fermenting inside sealed bottles and releasing gas, while commercial producers force-carbonate their drinks in pressurised tanks. The word appears almost exclusively in technical and trade contexts — breweries, soft-drink plants, and industrial chemistry — and is essentially never used figuratively. It derives from "carbonate," itself rooted in Latin carbo, meaning charcoal, tying this everyday pleasure back to one of chemistry's most fundamental elements.
verb (present participle of carbonate)The act or process of dissolving carbon dioxide gas in a liquid under pressure, giving it effervescence; more broadly, treating or combining something with carbon dioxide.
- Dissolving carbon dioxide in a liquid (especially water or beer) under pressure so that it becomes fizzy or sparkling.
- Treating a substance with carbon dioxide more generally, as in industrial or chemical processes.
"The brewery spent the weekend carbonating a fresh batch of pale ale before it went into the taps."
"Home brewers often spend weeks carbonating their beer naturally by adding a small amount of sugar before sealing the bottles."
"The plant's new system for carbonating soft drinks runs continuously, injecting CO2 directly into the chilled syrup."
That satisfying hiss when you crack open a soda exists because someone deliberately forced carbon dioxide into your drink at pressure — carbonating is chemistry you can taste.

Etymology of carbonating
"Carbonating" is formed from the verb "carbonate," which entered scientific English in the late eighteenth century during the era of pioneering research on fixed air — what we now call carbon dioxide. The root is Latin "carbo," meaning charcoal or coal, which also gives English "carbon," "carbonic," and "carboniferous." The verb was coined by chemists describing compounds and solutions containing carbon dioxide; as the soft-drink and brewing industries grew in the nineteenth century, "carbonating" became the standard term for the industrial process of forcing CO2 into beverages.

How carbonating is actually used
Almost always used technically or commercially, in brewing, beverage production, and industrial contexts. It is rarely used figuratively and carries no emotional connotation; in everyday speech people are far more likely to say a drink is 'carbonated' than that it is 'being carbonated.'
Easily confused with carbonating
Carbureting means mixing air (or another gas) with fuel vapour, as in an engine carburettor, whereas carbonating specifically means dissolving carbon dioxide in a liquid.
