Perfume Notes Explained
Article Summary: Perfume notes are the materials in a fragrance sorted by how fast they leave your skin. Top notes are the small, light molecules you smell in the first minutes, citrus, herbs and aldehydes; heart notes are the flowers and spices that carry the middle of the wear; base notes are the heavy ones, musks, resins, woods and vanilla, that are still there at the end of the day. The three-tier pyramid was taught as a method by Jean Carles at the Roure perfumery school in Grasse from 1946 and is now the standard way brands describe a scent, though perfumers treat it as a convenience rather than a law. This guide explains what each tier does, what an accord is, why some perfumes have no pyramid at all, how to read the pyramid on a MOJ product page, and what the UAE's heat does to the order.
- Notes are ordered by volatility: the industry reference Poucher's ranks materials on a scale of 1 to 100, top notes 1 to 14, heart 15 to 60, base 61 to 100.
- An accord is several materials blended to read as one smell; the oldest famous one is the fougere, lavender, coumarin and oakmoss, from Houbigant's Fougere Royale of 1882.
- Some fragrances are built to smell the same from first spray to drydown, and one, Molecule 01 (2006), is a single material, Iso E Super, with no pyramid to read.
- Heat speeds evaporation, so in the Gulf the top notes go sooner and the base arrives earlier than the pyramid on the box suggests; buy for the base.
- Concentration is a separate idea from notes: eau de toilette, eau de parfum and extrait are roughly 4 to 8, 8 to 15 and 20 to 30 percent perfume oil, with no regulated definition.
What a perfume note is
A note is not a separate smell added to a bottle. A perfume is one liquid, and every material in it evaporates from your skin at its own speed. The small, light molecules leave first and the heavy ones last, so what you smell at minute one is not what you smell at minute ninety, and the pyramid on the box is just that sequence written down in three tiers. Top notes are the materials that go first: citrus peel, mint, herbs, the sparkling aldehydes of a classic floral. Heart notes, also called middle notes, are what you smell once the opening has gone: most flowers, most spices, green and fruity materials. Base notes are the slowest: musks, resins such as benzoin and labdanum, woods such as sandalwood and cedar, vanilla, oud and amber, the part that is still on your wrist when you get home.
The industry's reference work, Poucher's Perfumes, Cosmetics and Soaps, puts a number on it, ranking materials by an evaporation coefficient from 1 to 100: top notes sit between 1 and 14, heart notes between 15 and 60, base notes between 61 and 100. The heart typically takes over within the first quarter of an hour and the base is already perceptible by then, so the tiers overlap rather than take turns. A good perfume is written so that the handover is smooth; a bad one has a gap in the middle where the citrus has gone and the musk has not yet arrived.
Who taught the pyramid, and what it leaves out
The three-tier idea is older than the word for it, and Francois Coty's Chypre of 1917 is the fragrance most often credited with making the structure famous. The method of teaching it belongs to Jean Carles, the Grasse perfumer who founded the Roure perfumery school in 1946 and taught students to build a fragrance from the base upward by volatility, learning materials in a grid that is still, in one form or another, the standard perfumery curriculum. Carles' categories were a teaching aid, and the pyramid printed on a box today is a marketing one: it tells you the direction of travel, not the proportions, and it says nothing about how much of each material is in the formula, which is the thing that actually decides what you smell. Two fragrances can list the same twelve notes and smell nothing alike. Read the pyramid for the base and the family, not as a recipe.
What an accord is
An accord is several materials blended so that the nose reads them as one thing. A rose accord is not rose oil but a dozen materials that together smell like a rose, and a "dates accord" in a Gulf gourmand is sugar, dried fruit and spice materials that together smell like dates. The most famous accord in perfumery is the fougere, lavender, coumarin and oakmoss, the backbone of Houbigant's Fougere Royale of 1882 by Paul Parquet, the first fragrance to use synthetic coumarin and, by most accounts, the first abstract perfume, one that smelled like no single flower. Every barbershop fragrance since, and most of the men's aisle, descends from that accord. When a MOJ pyramid lists "marine accord" or "ambergris", it means a blend built to read as the sea or as ambergris, not the thing itself.
Perfumes with no pyramid
Not every fragrance moves. Some are written to be linear, to smell the same from the first spray to the end of the wear, and the extreme case is Escentric Molecules' Molecule 01, launched in London in 2006 by Geza Schoen and made of a single material, Iso E Super, diluted in alcohol. There is no top, heart or base because there is only one molecule, which is why some people cannot smell it at all and others are followed round the room by it. Most of the big Gulf and gourmand scents sit between the two: Baccarat Rouge 540 reads nearly the same for its whole wear, while a classic chypre such as the Aventus structure changes completely from pineapple to smoke. If a product page cannot give you a pyramid, that is usually why, not an omission.
How to read a MOJ pyramid before you buy
Every MOJ product page lists the reading's top, heart and base in the house's own order, and the useful trick is to read it backwards. Four examples from the UAE store, all available in every size on October 24, 2026.
Alien has three materials and nothing else: jasmine sambac on top, cashmeran in the heart, amber at the base. That is a pyramid in name only; it is one chord held for the whole wear, which is why the original is recognised across a room. Delina is the opposite: litchi, rhubarb, bergamot and blackcurrant on top, Turkish rose and peony in the heart, cashmeran, incense and cedar at the base, and the whole point is the journey from fruit to rose to warm wood. Black Orchid has a top of truffle and gardenia that is gone in minutes and a base of chocolate, patchouli and incense that is the real fragrance; buy it for the base or not at all. Khamrah opens on cinnamon and nutmeg, but the dates, praline and vanilla underneath are what you will wear for the evening. In each case the base tier is the one that decides whether you will like the bottle at the end of the day, and the top tier is the one that decides whether you will like it in the shop. Shops sell on the top; wear is decided by the base.
What the UAE heat does to the order
Heat speeds evaporation. That is physics, not opinion: warmer skin pushes the light molecules off faster, and humidity carries them away, so in Dubai in August the top notes of any fragrance are shorter than they would be in Paris in April and the base arrives sooner. Three practical consequences. First, a scent that is all top, a cologne or a citrus splash, is gone before lunch here, which is why the Gulf wears heavy bases, oud, amber, musk and vanilla, all year and lets the heat do the projecting. Second, in summer spray less rather than lighter: two sprays of a base-heavy scent will carry, four will be a problem for the people around you. Third, test on skin, not paper, and give it twenty minutes before deciding, because the shop opening will have gone by the time you reach the car. Our long lasting perfumes guide picks by base notes for exactly this reason, and layering is the Gulf's other answer: a musk or oud underneath to hold the lighter scent on top.
Notes are not strength
Two separate ideas get mixed up on the box. Notes are what is in the perfume; concentration is how much of it is in the alcohol. Eau de cologne is roughly 2 to 4 percent perfume oil, eau de toilette 4 to 8, eau de parfum 8 to 15, parfum 15 to 25 and extrait 20 to 30, by the Perfume Society's ranges, and there is no regulated definition: brands set their own, and the same name on two bottles can mean different strengths. An eau de parfum does not have more notes than an eau de toilette of the same scent; it has more of them, so the base lasts longer and the top is often rebalanced. MOJ sells every reading at one concentration, so the pyramid on the page is the whole story.
What the pyramid will not tell you
Two things that matter and never appear on it. The first is the formula: the pyramid lists materials, not amounts, and a perfume that names oud in the base may contain a trace or a flood. The second is the regulatory list. Since 2023 the industry's safety body, IFRA, has restricted the use of nearly fifty more materials under its 51st Amendment, which is why some classic fragrances have been quietly rewritten, and the European Union has expanded the fragrance allergens that must be named on the label from 26 to 81, with new products required to comply from July 2026 and everything on sale by July 2028. Those names, linalool, limonene, coumarin and the rest, are the materials behind the notes, and they are the list to read if you react to perfume rather than the pyramid. If you are new to the idea of readings, what inspired perfumes are explains how MOJ builds one from a pyramid, and the ten the country searches for most are in our best perfumes in the UAE list, every one with its pyramid printed.
How to use notes to choose
Decide the base first: musk if you want clean, oud or amber if you want warm, vanilla or praline if you want sweet, woods if you want dry. Then pick the heart that suits the occasion, flowers for the day, spices for the night. Treat the top as the first impression and nothing more. If the pyramid has one material per tier, expect a scent that does not change; if it has five, expect a journey, and make sure you like where it ends. Our women's and men's collections print the pyramid on every page, and a 30 ml bottle is the size to learn one on.
