The olfactory pyramid is the tool used in perfumery to understand how a fragrance develops on the skin. It represents a sensory map that reveals which notes we will perceive first, which will linger the longest and which will stay with us until the end.

Knowing how to interpret it is key to choosing perfumes that suit you, your style and the moment you are going to wear them.

The three heights of the olfactory pyramid

The olfactory pyramid of a fragrance is divided into three layers that evolve over time:

Top notes

They are the first impact, the notes that greet you as soon as the perfume touches your skin. They are usually fresh and ephemeral: citrus fruits, juicy fruits, aromatic herbs...
At Xerjoff's Erba Pura, The top notes combine lemon, orange and bergamot for a vibrant impression that disappears in a few minutes, giving way to the fruity heart.

Heart notes

They appear when the top notes dissipate, and are the soul of the perfume. They usually last for several hours and are made up of denser notes, such as flowers, spices, fruity notes,...

At Radical Rose Extrait de Matiere Premiere, The centifolia rose shines at this point, accompanied by saffron which gives it a seductive and deep character.

Base notes

They are the base and anchor of the perfume. They are perceived when the rest of the notes have evaporated, and can last for hours or even days in fabrics. Here we find woods, resins, musks and vanillas.
Ani de Nishane is a perfect example: its base of vanilla, benzoin and musk creates an enveloping trail that is still present at the end of the day.

How to use the olfactory pyramid to choose your perfume

• Think in the momentIf you are looking for a fresh scent for the day, prioritise lighter top notes and heart notes; for the evening, go for intense and warm base notes.
• Get to know yourselfIf you know that you love a note (e.g. vanilla or jasmine), check where it appears on the pyramid. This will influence how long you perceive it.
• Test and waitDon't judge a perfume only by its fragrance. The true personality is discovered as you move through its pyramid.

More than theory: a tool for enjoyment

Understanding the olfactory pyramid of perfumes not only helps you make better choices, it transforms the way you experience your fragrances. You begin to notice the nuances, to anticipate how the scent will change over the hours, and to enjoy the journey that each perfume offers.
