Definition
The term originates from wine (decanting a bottle into a carafe), and was adapted into perfumery community usage in the early 2000s as online collector networks developed. A decant is distinct from a manufacturer's sample: it is created by a third party, not the brand. It is also distinct from a split, where a group collectively purchases a full bottle and divides the contents.

In practice
Decants are traded through niche perfumery communities on Basenotes, Reddit (r/fragrance), and specialist platforms. They typically range from 1 ml to 10 ml. A decant allows a buyer to experience a full-bottle fragrance for several wearings before committing to a full purchase, which is especially relevant for costly niche releases (Fragrantica community, accessed 2026-05-27).
Legally, selling decants occupies a grey area in most jurisdictions: the decanter is reselling a product without the original manufacturer's authorization and packaging. Most niche houses tolerate the practice informally. The quality of a decant depends heavily on the transfer method: heat, light, and air exposure during decanting can degrade top notes (Now Smell This, accessed 2026-05-27).
