How to understand scent notes?

Every fragrance unfolds gradually—not all at once. When you first smell a fragrance, you only perceive its opening notes, but after a few minutes or hours, new layers of the scent begin to emerge. That’s why fragrance compositions are divided into top, middle, and base notes.

Top Notes

Top notes are the first impression of a scent. You experience them immediately after opening a bottle, lighting a scented candle, or using an essential oil for the first time.

These notes are light, fresh, and vibrant, but they fade the fastest—usually within 5–15 minutes. Their purpose is to pique your interest and naturally transition into the heart of the scent.

The most common top notes include:

• citrus fruits (bergamot, lemon, orange, grapefruit);
• refreshing herbs (lavender, basil, mint);
• light floral accords (neroli);
• green notes.

Heart (Middle) Notes

Once the top notes have faded, the heart of the fragrance—the core character of the scent—is revealed.

Heart notes begin to emerge after about 10–30 minutes and typically last 2–4 hours. They make up the largest part of the fragrance composition and bridge the fresh initial impression with the rich base.

The most common middle notes include: It is the middle notes that most often determine how you’ll describe the fragrance—floral, fruity, spicy, or fresh.

• floral aromas (rose, jasmine, ylang-ylang, peony);
• spices (cinnamon, nutmeg, cardamom);
• tea, fruit, or green accords;
• light woody notes.

Base (foundation) notes

Base notes form the foundation of a fragrance and are its longest-lasting component. They unfold gradually once the top and middle notes have already faded.

These notes consist of heavier, slower-evaporating aromatic molecules, so they can be detected for anywhere from a few hours to a day or even longer, depending on the fragrance’s composition.

Base notes are most commonly composed of: Base notes give the fragrance depth, warmth, and richness, and help the entire fragrance composition last longer.

• woodsy scents (cedar, sandalwood, agarwood);
• musk;
• vanilla;
• amber;
• patchouli;
• vetiver;
• resins and other rich, earthy accords.

Why is it important to know the notes of a fragrance?

Describing the notes of a fragrance helps you better understand how the scent will change over time. For example, if you first smell a bright citrus note, that doesn’t mean the scent will remain the same half an hour later—it may be replaced by soft floral notes, and later a warm base of wood or musk will emerge.

Therefore, when choosing an essential oil, perfume, or scented candle, it’s worth paying attention to all three note groups. Only together do they create the full story of a scent—from the first impression to the long-lasting aroma.
