How to train your nose for perfumery: exercises and method

The nose is trained like a sensory skill: through repeated exposure, comparison, memorization, and putting things into words. It is not necessary to immediately recognize a substance in order to make progress. The goal is to gradually build benchmarks between scent, vocabulary, substance, and evolution.

1. What it means to «train your nose»

In perfumery, training your nose does not consist solely of memorizing lists of notes. It is primarily about learning to detect differences, comparing scents, and describing their qualities with an increasingly precise vocabulary.

A person can recognize a rose without being able to explain whether they find it fresh, honeyed, fruity, spicy, or powdery. Training consists precisely of adding these layers of interpretation.

2. Start with a small corpus of substances

It is better to know a few references in depth than to smell dozens of substances without being able to compare them. For an initiation oriented toward oriental perfumery, an initial corpus might include:

• rose;
• jasmine;
• orange blossom;
• saffron;
• cardamom;
• vanilla;
• benzoin;
• frankincense;
• oud;
• sandalwood;
• vetiver;
• patchouli.

This selection covers several families and already allows you to work on the contrasts between floral, spicy, woody, resinous, balsamic, and earthy.

3. Exercise #1: five words without looking at the answer

Smell a substance or a perfume without reading its description. Immediately write down five words. Do not try to be exact: note down what comes to mind spontaneously.

Next, consult the reference and compare. The gaps are instructive: they show which aspects you already perceive and which ones require more practice.

4. Exercise #2: finding contrasts

Place two substances side-by-side and look for the differences rather than the similarities.

Some useful pairs:

5. Exercise #3: working on a single axis

Instead of trying to identify a substance, choose a perceptual axis: warm/fresh, dry/damp, bright/dark, light/dense, or creamy/powdery.

Then classify several references on this axis. This exercise helps to build a sensory vocabulary even when the precise identification of the substance remains uncertain.

6. Exercise #4: memorizing a substance through several facets

For each substance, create a small index card:

• Name: substance or reference.
• Family: floral, woody, spicy, etc.
• Three facets: the most striking qualities.
• An analogy: a familiar image or object.
• An opposition: a substance with which it contrasts.
• Evolution: what changes after a few minutes.

This method creates multiple recall paths instead of a simple "name = scent" association.

7. Exercise #5: blind recognition

Once a few references are well-known, ask someone to present them without revealing their name. Start with only two or three substances.

Good practice involves providing a description first, then a hypothesis. Do not turn a correct answer into a requirement to "guess": the goal is to learn to recognize characteristics.

8. Training olfactory memory

The memory of a scent becomes more useful when it is associated with multiple pieces of information. For a substance, remember its name, its family, a few facets, its origin when relevant, and a concrete sensory experience.

Spaced repetition can help: reviewing a substance on the same day, then a few days later, and again after a week or two makes it possible to test what is actually memorized.

9. Do not smell for too long

Olfactory fatigue can reduce the quality of the analysis. Short, comparative sessions are generally more useful than one long session where all the scents end up mixing together.

Alternate between substances and take breaks. When your perception becomes confused, stop the exercise rather than trying to force an identification.

10. The environment matters

To compare correctly, limit parasitic scents as much as possible: food, smoke, household products, heavily scented cosmetics, or a very odorous environment.

Also keep the substrate, the quantity, and the observation time constant when comparing several references.

11. Blotter or skin?

The blotter is particularly practical for comparative learning: it allows you to test several references in relatively similar conditions. Skin is essential for then understanding the perfume in a real-world wearing situation.

For training, start with blotters to learn the substances, then move to skin to study evolution and diffusion.

12. A four-week program

After four weeks, restart the cycle with new substances or more complex references. Progress comes primarily from consistency.

13. From substances to perfumes

Once substances are better known, the exercise becomes more interesting: smell a perfume without consulting its pyramid, describe it, identify two or three dominant families, then look for the possible substances.

Finally, compare your hypothesis with the published composition. The goal is not to recover the entire formula—usually impossible based on scent alone—but to understand how substances and accords produce an overall impression.

14. Errors to avoid

• immediately looking for the name of the substance;
• memorizing only lists of notes;
• smelling too many references in a row;
• confusing analogy with chemical identification;
• viewing an incorrect identification as a failure;
• forgetting to note the evolution over time.

Key takeaways

Training your nose consists of developing comparative benchmarks. Start with few substances, describe before consulting the answers, work on contrasts, repeat at spaced intervals, and gradually move from isolated substances to complete perfumes. For oriental perfumery, woods, resins, flowers, and spices constitute an excellent training ground.
