How to Read a Fragrance: Top, Heart and Base Notes Explained
Every product page lists three layers of notes. What each layer is, when you smell it, how long it lasts, and which layer to choose by for a car, a diffuser or a room spray.

Every fragrance on this site lists its notes in three rows: top, heart and base. It looks like a recipe. It is really a timeline — the order in which the materials evaporate, and therefore the order in which you smell them. Read it as a timeline and the three rows tell you almost everything about how a scent will behave in your car or your home.
Top notes: the first minute
Top notes are the lightest materials — citrus, herbs, green leaves, light spices such as pink pepper or cardamom. They evaporate fastest, so they are what you smell when you open the bottle, spray the room or first get into the car. They announce the fragrance and then step aside; in a warm room they are gone within fifteen minutes, in a hot car within a day.
Heart notes: the first hour
Heart notes are the middle weight — flowers, tea, most spices, softer resins. They arrive as the top fades and hold for an hour or more. When two fragrances share a family, the heart is what tells them apart: two woody scents may both rest on oud, but one carries rose in the heart and the other carries saffron, and they are different fragrances because of it.
Base notes: the weeks after
Base notes are the heaviest materials — oud, sandalwood, cedar, amber, vanilla, musk. They evaporate slowly, which is why they are still there when everything else has gone. In a hanging bottle or a reed diffuser, which work for weeks, the base is what you actually live with. It is also what survives the heat of a parked car.
Choosing by layer
- For a hanging bottle or a vent clip, choose by the base. It is what remains after the first hot afternoon, and it needs to be something you like on its own.
- For a reed diffuser, choose by the heart and the base. A diffuser throws slowly and steadily; the heart gives the room its character, the base gives it persistence.
- For a room spray or a cabin spray, choose by the top. It is a one-hour fragrance; what you smell first is most of what you get.
- If you are buying for someone else, choose a fragrance whose base you already know they like — a base is the safest bet, because it is the part of a scent nobody grows tired of.
An example from the range
Oud Route opens with a flash of pink pepper (top), settles into smoke and a little rose (heart), and stays as oud over cedar (base). In a car in July the pepper is gone by the second day, the rose by the end of the week, and what you drive with for the next five weeks is the oud and the cedar. That is why it is sold as a car fragrance and why its base is the reason to buy it.
Questions people ask
Why does a fragrance smell different after an hour?
Because the top notes have evaporated and the heart has taken over. That is by design: the top is the greeting, the heart is the character, and the base is what stays. Judge a fragrance by the heart and base, not by the first minute.
Which notes matter most for a car fragrance?
The base. A hanging bottle or a vent clip works for weeks, and heat strips the top and heart within days, so a car fragrance is essentially its base notes. Choose oud, woods, amber or musk in the base.
Which notes matter most for a room spray?
The top and the heart. A spray is smelled in the first minute and gone within an hour or two, so the base rarely matters. Choose by what you smell first.
