Decant vs Full Bottle: Which Should You Buy?
Buy a decant when you want to test a scent, rotate several fragrances or travel light — you get the exact same juice for a fraction of the upfront cost. Only buy a full bottle once a fragrance is a confirmed favourite you wear constantly. Decants (2ml, 5ml, 8ml, 30ml) cut the risk of an expensive blind buy to almost nothing.

The Real Cost Comparison
A full bottle wins on price per millilitre — but only if you finish it. A decant wins on the cost of finding out whether you'll wear it at all.
| Decant | Full Bottle | |
|---|---|---|
| Upfront cost | Decant€7.95 – €25.90 | Full Bottle€90 – €300+ |
| Cost per ml | Decant≈ €3.24 / ml (8ml) | Full Bottle≈ €1.20 / ml (100ml) |
| Cost to try a new scent | Decant€7.95 | Full Bottle€120 (full bottle) |
| If you end up not loving it | DecantYou're out only a few euros | Full BottleYou're stuck with 90ml+ unused |
The decant figures are current Scento decant prices (8ml ≈ €3.24/ml). The bottle figures are illustrative typical EU retail prices for a designer 100ml eau de parfum and vary by brand — they're an example, not a quote.
When Each One Wins
There's no one-size-fits-all answer — it depends on where you are in your journey with a scent.
Choose a decant when …
- You haven't worn the scent for a full day yet — skin chemistry changes everything.
- You like to rotate several fragrances depending on mood, season or occasion.
- You're travelling and want a carry-on-friendly travel spray.
- You're tempted by an expensive bottle and want to defuse the blind buy first.
Choose a full bottle when …
- It's a confirmed signature scent you already wear several times a week.
- You'll realistically finish it, which makes the lower price per ml worth it.
- You want the presentation of the original bottle on your shelf.
Common Questions
What people weigh up before deciding.
Is it worth buying a full bottle of perfume?
Only if you're sure you'll wear it often. A full bottle has a lower price per ml, but most people own bottles they barely touch. Confirm a scent is a real favourite with a decant first — then a bottle is a sensible buy. At Scento, the price of your sample counts toward the full bottle of the same perfume if you buy it within 30 days, on the perfumes we also sell as a full bottle.
How long does a 5ml decant last?
A 5ml decant gives around 75 sprays — roughly three to four weeks of regular wear, or far longer if it's one of several scents you rotate. That's enough to live with a fragrance across different days and seasons before you commit.
Are decants cheaper than full bottles?
Per millilitre, a full bottle is usually cheaper. But the cost of actually trying a scent is far lower with a decant — a few euros versus €100+ — which is why decants win for discovery and bottles only win for scents you've already decided on.
Should I blind buy a full bottle?
Rarely. A blind-bought bottle you don't like is an expensive mistake that's hard to undo. A decant lets you test the full development on your own skin first, so that a later bottle purchase is a confident decision rather than a gamble.
How can you try expensive designer perfumes without buying a full bottle?
Buy a decant instead of a bottle. A decant is a small, hand-poured measure of the exact same fragrance in a 2ml, 5ml, 8ml or 30ml size, so you can test an expensive designer or niche scent from around €7.95 rather than paying €100+ for a full bottle you haven't lived with. You wear it across several days and seasons, and only commit to a bottle once you're sure it's a favourite.
