Q. What Is Scent?

A. Scent does not exist as a single “thing”; it is “a collection of countless molecules.” For example, in 1900, the scent of a rose was thought to consist of eight molecules, but the latest technology has shown it to contain 400 or more. When these interact with our sense of smell, we perceive scents and odors.

If you smell them, you will find pure natural materials more interesting than chemical fragrance materials. That is because most natural materials are mixtures of dozens or hundreds of molecules, which our sense of smell perceives as richness and depth.

At the same time, scent also calls up our memories. Think of it like this: we smell □□ → the information is transmitted to the brain → based on past experience, we sense the smells of ○○ and △△ → we recognize this as the scent of □□. Our sense of smell can therefore be sharpened through experience.

It is commonly said that a perfumer’s olfactory ability is 100 times that of an ordinary person. Training your sense of smell requires long-term practice in thinking about what you are smelling when you encounter a variety of scents, not just perfumes. It is also important to gain some experience smelling individual fragrance materials.

Technique can be learned, and in the world of perfume it is learned through hard work. Criticism of perfume cannot be improvised, any more than criticism of music, painting, or literature can.
