If you spend any time in the fragrance world, you'll hear the word decant within minutes. It gets used alongside sample, tester and travel size as if they were interchangeable - they aren't. This guide defines each term precisely, shows how they compare, and explains why decants have become the standard way collectors and beginners alike try perfume before buying a full bottle.
What is a perfume decant, exactly?
A decant starts life as a full-size, sealed bottle of the original fragrance. A seller (or a friend with a big collection) sprays or pours part of it into a clean, empty atomizer, labels it, and sells it by the millilitre. Nothing is diluted, mixed or altered - a decant of Tobacco Vanille is Tobacco Vanille, at the exact concentration Tom Ford bottled it at.
Decants exist because full bottles of luxury and niche perfume routinely cost €150-400, and nobody can know from a 30-second sniff in a store whether a scent works on their skin for eight hours. Buying 5 ml for a fraction of the price answers that question properly.
Decant vs sample vs tester vs travel size
| Term | What it is | Typical size | Who fills it |
|---|---|---|---|
| Decant | Refilled spray taken from an original bottle | 2-10 ml | A decanter/seller, by hand |
| Sample | Tiny vial made by the brand for promotion | 0.7-2 ml | The perfume house, at the factory |
| Tester | Full-size store display bottle, plain packaging, no cap | 50-100 ml | The perfume house |
| Travel size | Official miniature sold at retail | 7.5-15 ml | The perfume house |
Decant vs sample - the difference that matters
Both contain authentic juice; the differences are who fills them, what you can get, and how much you get. Brand samples are factory-sealed but tiny (often under 1 ml - two or three wearings), free-with-purchase or bundled in discovery sets, and only exist for fragrances the brand chooses to promote. Decants are hand-filled but available for almost any fragrance in any size - including discontinued gems, boutique exclusives and niche houses that never make samples. If you want to properly live with a scent for a week or two, a decant is the only realistic option.
Decant vs tester - don't confuse them
A "tester" is a full bottle in plain packaging, made for store counters and often sold at a discount. It's full size, not a small format. If you see a "5 ml tester" advertised, the seller almost certainly means a decant or a sample.
Are decants authentic? (and are they legal?)
A decant is exactly as authentic as the bottle it came from - that's the whole game. Reputable decanters buy original sealed bottles, fill sterile atomizers by hand and label everything clearly. Selling decants is a well-established practice in the fragrance community; what matters for you as a buyer is trusting your source. Look for a seller who states where their bottles come from, uses fresh sprayers, and stands behind authenticity - here's how we handle it.
One honest caveat: because a decant is opened and hand-filled, it is not a factory-sealed product. What you gain in exchange is choice and size - and a fragrance that has been stored properly loses nothing in the transfer.
Why buy decants at all?
1. Try before you invest. A blind buy at €250 that you end up hating is the most expensive mistake in perfumery. A decant answers the question for a few euros.
2. Wear the wardrobe, not the bottle. Ten 5 ml decants cost less than one full bottle and give you a rotation for every mood, season and occasion.
3. Travel without risk. A 10 ml spray is carry-on friendly and you won't cry if it breaks.
4. Access rare scents. Discontinued, boutique-exclusive or hard-to-find fragrances often circulate only as decants.
Not sure how much you need? A 2 ml is roughly 20 sprays, a 5 ml about 50, a 10 ml about 100 - full breakdown in our guide how long does a perfume decant last?

What does decant mean in perfume?
A decant is a small spray (usually 2-10 ml) hand-filled from an original full-size bottle. The word comes from "decanting" - pouring liquid from one container into another. Same fragrance, smaller format.
What's the difference between a decant and a sample?
A sample is a tiny factory-made vial (often under 1 ml) that brands produce for promotion; a decant is hand-filled from a retail bottle in the size you choose. Decants exist for nearly every fragrance - samples only for the ones brands decide to promote.
Are decants real perfume?
Yes - a decant contains the exact original juice at its original concentration. Nothing is diluted or altered; it's the same liquid transferred to a smaller sprayer.
Is buying decants legal?
Buying and selling decants of genuine perfume is an established practice in the fragrance community. The key is buying from a transparent seller who decants from authentic retail bottles.
How many wearings is a decant?
Around 3-4 full wearings from a 2 ml, a few weeks from a 5 ml, and a month or more from a 10 ml - see the full calculator.
