What does decanting mean?
Decanting is the process of gently pouring a liquid from one container into another so that unwanted sediment stays behind, or so that the liquid mixes with air. It is most familiar from wine culture: an older red wine may be decanted to leave its natural deposits in the bottle, while younger wines are sometimes decanted simply to aerate them and soften their flavour. The term also appears in chemistry and industry, where decanting describes separating a liquid from solids by careful pouring. As a gerund or participle it functions as part of the verb 'to decant', and as a noun it names the act itself. The word lends an air of care and precision wherever it appears, suggesting that the transfer is being done deliberately and skilfully rather than casually. Its Latin roots lie in 'de-' (from) combined with 'canthus', meaning the rim or spout of a vessel, which also gives us the anatomical term 'canthus' for the corners of the eye.
The process or instance of pouring a liquid from one container into another, especially to separate it from sediment or to aerate it.
"Proper decanting requires a steady hand and good light to spot when sediment begins to reach the neck of the bottle."
Most common in wine contexts; also used technically in chemistry for separating liquids from solids.
Present participle and gerund of 'decant': to pour a liquid gradually from one container into another, especially without disturbing sediment.

Rarely used; the uncountable singular form is standard even when referring to repeated acts.

Every time a waiter slowly tips an old bottle into glass, they're performing a ritual whose very name comes from the Latin word for the spout of a vessel.

Etymology of decanting
Decanting derives from the verb 'decant', which entered English in the early 17th century from French 'décanter'. The French word combines 'de-' with 'canter', ultimately rooted in Latin 'canthus', meaning the rim or spout of a vessel, itself borrowed from Greek 'kanthos', which originally referred to the corner of the eye and came to describe angular edges generally. The same Latin-Greek root underlies related words such as 'canthus' and 'cant' in the sense of an edge or slope.

How decanting is actually used
The word is most strongly associated with wine service, where it carries connotations of refinement and expertise, but in scientific and industrial contexts it is a neutral technical term. It is somewhat formal in register; in everyday speech people more often say 'pouring off' or 'pouring out'.
