You found a fragrance you might love. It costs $325 for a bottle you've never smelled on your own skin. This exact moment is why decants exist — and if you've ever wondered whether they're legit, how big they are, or why they cost a fraction of retail, this guide answers everything honestly.
What is a perfume decant?
A decant is a small amount of a genuine fragrance — typically 1ml to 8ml — transferred by hand from an original retail bottle into a smaller spray atomizer. Nothing is added, diluted or altered: it's the exact same liquid the boutique sells, in a size that lets you actually live with a fragrance before committing to (or instead of) a full bottle.
Decant vs. sample vs. clone — they are not the same thing
- Decant: the real fragrance, hand-filled from an original bottle. Same scent, same performance.
- Manufacturer sample: also real, but usually 1–2ml vials with no spray, given away at counters — hard to find for niche houses.
- Clone / dupe / "inspired by": a different, cheaper formula built to imitate the original. Some are decent; most collapse within the hour. A clone is never the fragrance it copies.
Are decants legit? How do I know it's authentic?
The honest answer: it depends entirely on who you buy from. The decant market has both careful specialists and sellers who cut corners. Whoever you choose, look for three things: (1) they show how they decant, (2) they name their sourcing, and (3) they answer questions about specific batches. At Fragmentum, every decant is filled by hand, to order, from an original sealed bottle bought at authorized retailers — and we document the whole process on our Authenticity Promise page. You can even email us your order number and ask about the source bottle of your batch.
What size should I get?
- 1ml — first contact. About 15–20 sprays. Enough to wear a fragrance twice and know if it deserves more of your skin. Starts around $6–9.
- 3ml — the discovery size. Around 40–45 sprays: two or three weeks of real wear, through different weather and moods. The best size for deciding.
- 5ml — the travel companion. Roughly 70–80 sprays. Fits any pocket or bag; ideal once you know you like it.
- 8ml — the keepsake. 100–110 sprays of a fragrance you already love — usually the best value per spray, engraved and yours.
How much do you actually save?
Take Baccarat Rouge 540: about $325 for 70ml at the boutique. A 1ml decant costs about $9 — you experience the identical fragrance for under 3% of the price. Across a year, a rotation of five or six decants costs less than one full bottle, and you'll never be stuck with 95ml of something you stopped loving in March.
How to store a decant
Same rules as any fragrance, smaller scale: keep it away from direct sunlight and heat (not the bathroom shelf), cap it tightly, and it will stay true for many months. Glass atomizers — the only kind we use — preserve the scent far better than plastic.

Quick answers
Do decants smell weaker than the bottle?
No. Strength lives in the liquid, not the container. A decant sprays the same concentration the original bottle does.
Is it legal to sell decants?
Yes — in the US, reselling a genuine product you own, accurately described, is legal under the first-sale doctrine. What matters is honesty about what's in the atomizer.
Why is there no brand box?
Because you're buying the fragrance, not the packaging. That's most of the saving — the juice is identical.
