Fragrance notes

Scent is described as having three sets of 'notes'. They  unfold over time, with the immediate impression of the top note leading to the deeper middle notes, and the base notes gradually appearing as the final stage. These notes are created carefully with knowledge of the evaporation process of the cologne.

• Top notes: The scents that are perceived immediately on application of a fragrance. Top notes consist of small, light molecules that evaporate quickly. They form a person's initial impression of a scent. Also called the head notes.
• Middle notes: The scent of a cologne that emerges just prior to when the top notes dissipate. The middle note compounds form the "heart" or main body of a fragrance.
• Base notes: The scent of a perfume that appears close to the departure of the middle notes. The base and middle notes together are the main theme of a cologne. Base notes bring depth and solidity to a perfume. Compounds of this class of scents are typically rich and "deep" and are usually not perceived until 30 minutes after application.
