Fragrance Notes Explained: Top, Heart and Base

Perfumers traditionally describe a fragrance as a pyramid of three stages, based on how quickly different ingredients evaporate:

• Top notes are the first impression: light, volatile ingredients such as citrus, fresh herbs and some fruits. They are usually noticeable for the first few minutes up to roughly half an hour.
• Heart notes (or middle notes) emerge as the top fades and form the character of the fragrance. Florals, spices, green notes and fruits are common here, and they typically shape the experience for the next couple of hours.
• Base notes appear last and linger longest. Woods, amber, musk, vanilla, resins, patchouli and oud are typical base ingredients, and they give a fragrance its depth and staying power.

These timings are rough guides, not rules. Skin, climate and concentration all change how a fragrance develops.

The pyramid is a helpful simplification, but real fragrances don't switch from one stage to the next like changing slides. Ingredients overlap, blend and evaporate at different rates, so the transition is gradual. Many perfumers prefer to think of a fragrance as a story with an opening, a development and a dry-down, the final stage you smell hours later once the lightest ingredients have gone.

That's why the first spray can be misleading. A fragrance that opens sharply with citrus may settle into something warm and creamy, and a sweet opening may dry down much drier. Judging a scent only by its first minutes is like judging a book by its first line.

You'll often see both notes and accords on fragrance pages. A note is an individual ingredient or scent impression, such as rose or cedar. An accord is a blend of several ingredients designed to create a single, new impression. A leather accord or a fresh aquatic accord, for example, may not contain anything literally made from leather or the sea.

Accords are a useful shortcut for browsing. If you know you enjoy woody and amber accords, you can explore fragrances that share them without memorising dozens of individual notes. The ScentWeave browse page lets you filter by accord for exactly this reason.

Published note lists are helpful but imperfect. Brands sometimes list notes for marketing appeal, and many ingredients in modern perfumery are synthetic or reconstructed, so a note called sandalwood might not be natural sandalwood at all. Think of the list as a guide to the overall impression rather than a precise ingredient label.

It also helps to remember that notes interact. Vanilla alongside smoke and leather smells very different from vanilla alongside peach and coconut.

• Citrus (bergamot, lemon, grapefruit, orange): bright, clean and energising; usually top notes.
• Florals (rose, jasmine, iris, lily of the valley): from powdery and soft to rich and heady; often at the heart.
• Spices (cardamom, pepper, cinnamon, saffron): warm or sharp, adding energy and character.
• Woods (cedar, sandalwood, vetiver, oud): dry, creamy or smoky foundations that anchor a fragrance.
• Resins and balsams (amber, benzoin, incense, labdanum): warm, sweet and enveloping.
• Musks: soft, skin-like and clean, widely used to add smoothness and longevity.
• Gourmand notes (vanilla, tonka bean, caramel, coffee): comforting, edible-smelling sweetness.

Compare the notes of fragrances you love. Recurring ingredients are your signature preferences. Then do the same for scents you dislike: you may spot a single note, such as a certain aromatic or a heavy sweet musk, that is the culprit. Once you know, you can search for fragrances that include your favourites and avoid the troublemakers. In ScentWeave you can even block notes you dislike so they're excluded from your recommendations.
