What is an olfactory pyramid?

Perfume is an art that appeals to our senses, our emotions and our imagination. But behind the magic of a fragrance, there is also a science, that of olfactory composition. To create a perfume, perfumers use an essential tool: the olfactory pyramid. What is this ? How is it built? What is his role ? We explain everything to you in this article.

What is an olfactory pyramid?

An olfactory pyramid is a schematic representation of the composition of a perfume, which is divided into three levels: top notes, heart notes and base notes.
Each level corresponds to a group of raw materials which have common olfactory characteristics, and which are revealed at different times during the evaporation of the perfume.

What is the objective of an olfactory pyramid?

The olfactory pyramid has several roles in the perception of a perfume. It permits :

  • To describe and classify perfumes according to their olfactory families. There are several possible classifications, but the most common distinguishes the flowery, oriental, woody, citrus, chypre-fern and aromatic families. There are also nuances linking families together. For example, we are talking about oriental woody.
  • To understand and predict the evolution of a perfume on the skin and in the air. Indeed, a perfume is not static, it changes over time and depending on external conditions. The olfactory pyramid allows you to know which notes will dominate at each stage of the diffusion of the perfume.
  • To choose and appreciate a perfume according to your tastes and desires. Indeed, each person has their own olfactory preferences, which depend on their history, personality, culture and mood. The olfactory pyramid allows you to guide yourself towards the perfumes that best correspond to your profile and your state of mind.

The olfactory pyramid is therefore a useful tool for perfumers, but also for perfume lovers. It reveals the complexity and richness of a fragrance, and invites you to discover it in all its aspects. It is also a means of expression and communication, which allows you to share your emotions and olfactory sensations.

How to properly use an olfactory pyramid?

An olfactory pyramid is a useful tool for choosing a perfume that suits your tastes and needs. This tool must, however, be used with discernment to reveal all its subtlety. The olfactory pyramid is above all present to define a feeling, but the feeling can be variable.
Olfactory perception can differ from one person to another, like color perception. The olfactory pyramid must therefore be seen as a useful and reliable guide but not as an absolute and universal truth.
Depending on the scented product,  the scent may manifest itself in a slightly different way. For example, on a reed diffuser, the base notes are more discreet. Capillary action involves continuous diffusion, the base notes are therefore less perceptible and the top notes more present than with a spray or eau de toilette.
The duration of perception of the notes can also vary depending on the concentration of perfume applied.
