Fragrance Terms Glossary: 40 Words, Plainly Defined

Fragrance has a vocabulary problem. Half of it is French, a quarter is borrowed from wine, and the rest was invented on forums. None of it is complicated, but almost nobody defines it before using it, which makes the whole subject feel more closed than it is.

This is every term you are likely to meet, in plain English, grouped by what it describes. Where a term deserves more than a sentence, there is a link to the page that gives it one.

Concentration and strength

Parfum / Extrait de Parfum: The most concentrated standard tier, roughly 20-40% aromatic oil. Longest lasting, most expensive, applied sparingly.
Eau de Parfum (EDP): Roughly 15-20% oil. The modern default for a serious fragrance and the best all-round choice for most people.
Eau de Toilette (EDT): Roughly 5-15% oil. Lighter and fresher; the standard for citrus and aquatic scents. Reapplication is normal, not a fault.
Eau de Cologne (EDC): Roughly 2-5% oil. The original meaning of "cologne" — a light citrus splash lasting two or three hours. Full detail in our concentrations guide.
Cologne (American usage): In everyday American English, simply "fragrance for men," regardless of strength. Both meanings are in active use, which causes constant confusion — see cologne vs perfume.
Attar / perfume oil: An alcohol-free fragrance suspended in carrier oil, applied by dabbing. Lasts much longer on skin, projects much less. See perfume oil vs cologne.

Structure and composition

Note: A single identifiable smell within a fragrance — bergamot, vanilla, cedar. Marketing pyramids list notes; real formulas contain far more materials than the pyramid names.
Accord: Several materials blended so they read as one new smell. A "marine accord" is not one ingredient; it is a constructed impression.
Top / heart / base notes: The three stages of a fragrance as it evaporates. Tops are light and brief, hearts carry the middle, bases are heavy and last for hours. More in fragrance notes explained.
Drydown: The final stage, once the tops and heart have burned off. What you are left with after a couple of hours, and the phase you actually live with.
Opening: The first few minutes after spraying. Often the most impressive phase and the least representative of the fragrance.
Fragrance family: The broad category a scent belongs to — fresh, floral, woody, oriental, fougere. See fragrance families explained.
Fougere: Literally "fern." A classic masculine structure built on lavender, coumarin and oakmoss. The barbershop shape.
Chypre: A structure built on citrus over oakmoss and labdanum. Earthy, mossy and slightly bitter.
Gourmand: Edible-smelling — vanilla, caramel, chocolate, dates. The most reliably complimented family and the easiest to overdo.
Aquatic / marine: Sea air, melon rind, wet stone. Built on synthetics invented in the late 1980s and dominant in men's fragrance ever since.
Ambroxan: A synthetic amber material found in a very large share of modern releases. Dry, mineral, slightly salty, and the reason a lot of recent fragrances smell related.
Oud / agarwood: A dense, resinous wood resin, among the most expensive materials in perfumery. Almost all affordable oud is a synthetic reconstruction. See best oud for beginners.

Performance

Longevity: How long a fragrance remains detectable on skin. Driven by concentration and base materials, not by price.
Projection: How far the scent travels from your body at a given moment. High projection is noticed across a table.
Sillage: Pronounced roughly "see-yazh." The trail you leave behind as you move through a space. Related to projection but not the same thing — see sillage and projection explained.
Beast mode: Community slang for a fragrance with extreme projection and longevity. Usually a compliment on a forum and a complaint in an office.
Skin scent: A fragrance that sits close to the body and is only detectable at conversational distance. The opposite of beast mode, and often deliberate.
Nose blindness / olfactory fatigue: Losing the ability to smell your own fragrance because your receptors have adapted to a constant signal. Happens within fifteen to thirty minutes and causes most over-application — see why you cannot smell your own cologne.

Buying and product terms

Flanker: A separate fragrance released under the name of an existing one — Sauvage Elixir, Ultra Male, Invictus Platinum. Flankers are different compositions, not different strengths of the same scent. This misunderstanding causes more bad purchases than any other.
Reformulation: A change to an existing fragrance's formula, usually for cost or regulatory reasons. Rarely announced. Long-term wearers of older classics report it constantly.
Vintage: An older bottle of a fragrance, from before a reformulation. Sought after, expensive, and a common vector for fakes.
Batch code: A production code printed on the bottle and box, used to date a bottle and to check authenticity. See how to spot fake cologne.
Clone: An original fragrance from a legitimate house, deliberately built to evoke a famous designer scent, sold under its own name. Legal. See are cologne clones worth it.
Counterfeit / fake: A bottle falsely claiming to be a branded product. Illegal, and entirely different from a clone. Never buy one knowingly.
Decant: A small amount of fragrance transferred into a travel atomizer or vial, sold or shared. The cheapest way to try something properly — see how to try cologne before buying.
Discovery set / sampler: A boxed set of small vials covering several fragrances. The standard way to find out what you like without buying full bottles.
Blind buy: Buying a full bottle without having smelled it. The most common way to waste money in this hobby.
Niche: A fragrance from a specialist perfume house rather than a fashion brand, distributed narrowly and priced high. See niche vs designer fragrance.
Designer: A fragrance sold under a fashion or beauty brand, usually produced under license by a fragrance group, and discounted heavily.
Tester: A bottle intended for retail display, often sold cheaply in plain packaging. Usually the same juice, sometimes without a cap.

Application and wear

Pulse points: Warm areas of the body — neck, wrists, chest — where heat helps a fragrance project. See how to apply cologne.
Layering: Wearing two fragrances together deliberately, or pairing a fragrance with a matching body product. See how to layer fragrances.
Signature scent: One fragrance worn consistently enough that people associate it with you. Less common now that most people own several.
Rotation / wardrobe: The set of fragrances you own and switch between by season and occasion. See how to build a fragrance wardrobe.
Scrubber: Community slang for a fragrance so unpleasant on your skin that you wash it off. Entirely subjective.
Compliment getter: A fragrance that reliably draws unprompted comment. Usually sweet, projective and legible rather than complex — see best smelling colognes for men.

Where to go next

If you are new and this is the first page you have landed on, the two most useful next reads are fragrance concentrations (which explains what you are actually buying) and how to choose your first cologne (which explains how to work out what you like). Neither assumes you know any of the words above.

How we picked

We did not lab-test this gear

Everyone in this category says they tested twenty products. We have not lab-tested any of these, and we say so. What we did instead: compiled the published specifications, decoded the ingredient (INCI) lists active by active, ran the math where there was math to run, and scored each product against a published rubric. The scores are judgments from documented research — not measurements we took, because we do not have a lab and we will not pretend we do. Where a number came from someone else's work, we name them in Sources.

Questions

Frequently asked

What is the difference between projection and sillage?

Projection is how far the scent reaches from your body at a moment in time. Sillage is the trail you leave behind as you move through a space. A fragrance can project modestly and still leave a noticeable trail, and the reverse is also true.

What does drydown mean?

The final stage of a fragrance, once the light top notes and the heart have evaporated. It is what you smell after a couple of hours and what you actually live with for the rest of the wear.

What is a flanker?

A separate fragrance released under the name of an existing one - Ultra Male, Sauvage Elixir, Invictus Platinum. Flankers are different compositions, not different strengths of the same scent, and confusing the two is the most common cause of a disappointing purchase.

What is the difference between a clone and a fake?

A clone is an original fragrance sold under its own brand name, built to evoke a famous scent. That is legal, because scent formulas are not protected the way trademarks are. A fake claims to be the branded product itself, which is counterfeiting and illegal.

What does EDP mean on a cologne bottle?

Eau de parfum - roughly 15-20% aromatic oil, the modern default for a full-strength fragrance. It typically outlasts an eau de toilette of the same scent, though the label describes an intended range rather than a guaranteed one.
