A sensory experience that challenges communication.

Smell, one of the oldest and most mysterious sense, envelops us in a world of elusive and fascinating perceptions. Unlike sight and hearing, where well-defined maps link physical properties to perceptions, the realm of odors is more indefinable. Conveying the complexity of a scent in words thus becomes an intriguing challenge, a task that requires a rich and shared vocabulary.

A maze of emotions and memories.

When a scent reaches us, our nose captures its molecules, sending signals to our brain. This is where the magic happens: we recognize and remember specific odors, but translating them into words is a different challenge. The difficulty is in the structure of the brain itself: the areas dedicated to smell are closely linked to those of emotions and memory, but not to those of language. This is why, despite clearly perceiving an odor, we struggle to describe it verbally.

An example of linguistic ambivalence is the word ‘Balsamic’: ‘Balsamic’ in common language means something camphoraceous, like  lavender or rosemary, while in the perfumery vocabulary it expresses the characteristics of a balm, a resin, hence it means resinous.

A limited vocabulary: in search of common expressions.

To describe odors, we often rely on metaphors and analogies. A scent can be “sweet as honey” or “fresh as a spring meadow.” But these descriptions are subjective, influenced by our personal experiences and cultural background. Some studies show that the language we speak can influence the perception of odors: different cultures categorize and describe smells in different ways, further complicating communication.

Challenges and opportunities for perfumers.

For master perfumers, developing a common language is essential. In fragrance creation, a technical vocabulary allows for precise descriptions of a perfume’s characteristics. However, for the general public, this language can be cryptic. That’s why perfumers often tell evocative stories behind each creation, using images and suggestions to convey the essence of a fragrance.

Technological innovations: a map for smell.

Science has made strides in mapping odors. An example is the “Principal Odor Map,” which uses graphical neural networks to represent the hierarchies and perceptual distances of odors. This map helps predict the intensity and perceptual similarity of scents, facilitating communication and understanding in the world of perfumery.

An ever-evolving olfactory journey.

Change is a constant in everyone’s life and our olfactory tastes also change. A scent we liked when we were young might no longer align with us in adulthood. Life experiences, emotions, and relationships influence our olfactory preferences. A fragrance can evoke memories, emotions, and tells a story without words. As Marcel Proust said, a scent can rekindle forgotten memories and transport us to distant times and places.

An invitation to explore the world of scents.

The language of odors is a fascinating and constantly evolving field. The challenge lies in finding ways to communicate these sensory experiences in a comprehensible and shareable manner. With advances in technology and a greater understanding of olfactory neuroscience, we are making progress in describing the mysterious world of odors.

Join my courses and enrich your vocabulary.

In my courses, I propose an immersive journey into the world of perfumery, also helping participants to enrich their vocabulary with specific industry terms. In each session, we explore the nuances of scents together and gradually discover how to translate them into words, opening the doors to a richer and deeper olfactory communication.
