Top, heart and base notes
Every fragrance is built in layers that appear at different times. Here is how the fragrance pyramid works and what it means for candles compared with perfume.
The fragrance pyramid
Perfumers describe a fragrance as a pyramid with three layers. The layers are based on how quickly each material evaporates.
- Top notes are light and evaporate fastest. They are your first impression.
- Heart notes, also called middle notes, appear as the top fades and form the main character.
- Base notes are heavy and slow to evaporate. They give depth and last longest.
Typical notes in each layer
| Layer | How long on skin (roughly) | Common examples |
|---|---|---|
| Top | Minutes to about half an hour | Lemon, bergamot, grapefruit, mint, pink pepper |
| Heart | A few hours | Rose, jasmine, lavender, cinnamon, fig |
| Base | Many hours | Sandalwood, cedar, vanilla, musk, amber, oud |
These times describe perfume on skin. They vary with the formula, the person and the weather.
How notes behave in a candle
A candle does not unfold over time in the same way as perfume on skin. Once the melt pool is warm, all the layers are released at once, so you smell the whole blend together. That is why candle makers think more about balance than timing.
Still, the layers matter:
- A candle heavy on top notes can smell bright in the jar but fade quickly in the air.
- A candle with strong base notes tends to linger in a room after you blow it out.
- Very light citrus notes are often supported by heavier notes so the scent keeps its shape when heated.
Accords
An accord is a mix of materials that smells like a single new thing. A "leather" or "amber" note in a candle is usually an accord, not one raw ingredient. Think of it like a musical chord: several notes played together to make one sound.
Reading a scent description
A candle label might say: "Top: bergamot, pink pepper. Heart: rose, jasmine. Base: oud, amber, musk." Read it as a story:
- It opens bright and slightly spicy.
- Its main character is floral.
- It settles into a warm, woody, slightly sweet trail.
Using fragrance families, you would call this a woody floral with amber depth.
Building your own combinations
When you burn two candles in one room or layer a candle with a diffuser, think in pyramid terms. A fresh top-note candle in the hallway and a warm base-note candle in the living room create a pleasant journey through the home. Our scenting every room guide has ready-made pairings.
Bergamot, a small citrus fruit grown mainly in the Calabria region of Italy, is one of the most widely used top notes in perfumery and gives Earl Grey tea its distinctive flavor.
