What do Top, Heart and Base notes mean?

Fragrance descriptions often refer to top, heart and base notes. These terms describe how the different parts of a fragrance may become noticeable over time.

Top notes are usually the first impression. Citrus oils such as lime, bergamot, mandarin and grapefruit often bring brightness and clarity to the opening of a blend.

Heart notes sit at the centre of the fragrance. Florals, herbs and spices can add softness, warmth or character as the composition begins to settle.

Base notes provide depth and remain noticeable for longer. Cedarwood, patchouli, frankincense, myrrh and vetiver can give a blend a warmer, earthier or more resinous character.

In a reed diffuser, these stages are not always as distinct as they may be in a perfume worn on the skin. The oils diffuse continuously, allowing the different notes to overlap and become apparent at different moments.

Understanding fragrance notes can still help you choose a blend. You may prefer the brightness of citrus, the softness of florals or the depth of woods and resins.

The Acoori Discovery Set contains samples of all ten diffuser blends, allowing you to experience each composition gradually before choosing a full-sized diffuser.
