How perfume is built—and how to read it

Discover how a fragrance evolves, how accords and notes shape what you smell, and how ingredients, families, and concentration fit together.

From perfume to its materials

  1. Olfactory pyramid with top, heart, and base

    1 · Evolution

    Top, heart, and base

    Read the pyramid as a sequence: top notes appear first, heart notes reveal the fragrance's character, and base notes linger on skin.

    Bright bergamot can give way to florals, then settle into woods or musks.

  2. Aromatic materials combined into perfume accords

    2 · Impression

    Accords create recognizable impressions

    An accord brings several materials together to suggest a recognizable impression, such as leather, amber, clean linen, or a gourmand effect. You may notice different accords as the fragrance develops.

    An amber accord might blend vanilla, resins, and warm woods.

  3. Perfumes and materials evoking different fragrance notes

    3 · Language

    Notes describe what we perceive

    Notes name what you perceive. They help you describe a fragrance, follow its development, and compare it with others.

    You can perceive notes of leather, rain, or cotton without those things being literal ingredients.

  4. Natural ingredients and perfumery molecules

    4 · Construction

    Perfumers build those notes from ingredients

    Natural raw materials and aroma molecules are measured and blended by perfumers to create notes and accords. A note does not necessarily come from a single ingredient.

    Several molecules, resins, and smoky facets can work together to create a leather impression.

    Understand ingredients

Ingredients representing fragrance families

Classification

Fragrance families summarize a fragrance’s dominant character

Use families such as citrus, floral, woody, and amber to identify a fragrance's dominant character and compare styles. One perfume can span several families.

A fragrance may have a floral heart and a woody base.

Perfume bottles associated with different concentrations

Format

Concentration is a guide, not a guarantee

Concentration can affect intensity, projection, and longevity, but the percentage alone does not tell the whole story. The formula, your skin, and the weather all matter.

An extrait may last for hours while projecting less than a bright Eau de Toilette.

Compare concentrations

A simple order for getting started

Start with the pyramid, then move through accords and notes before exploring how perfumers work with ingredients. Use families to compare styles and concentration to understand how a fragrance may project and last. Then put the framework into practice with real perfumes.
