A perfume is not one smell; it is a story in three acts. Different materials evaporate at different speeds, so what you smell changes over the day. Perfumers describe this with a pyramid: top, heart and base.
Top notes: the first 15–30 minutes
Small, light molecules that evaporate quickly: citrus peels, herbs, light fruits, pink pepper, aldehydes. They make the first impression, which is why you should never judge a perfume from the first spray alone.
Heart notes: from about 20 minutes to 4 hours
The character of the perfume. Florals (rose, jasmine, orange blossom), spices, green notes and fruits. The heart bridges the bright opening and the deep base.
Base notes: the dry down, up to a day or more
Large, heavy molecules that evaporate slowly: woods, musks, resins, amber, vanilla, patchouli, oud. They also act as fixatives, slowing the evaporation of the lighter notes above them.
The pyramid is a simplification
Modern perfumes, especially minimalist ones built on a few powerful molecules such as Iso E Super or Ambroxan, can smell almost the same from start to finish. These are called “linear” perfumes. Classic perfumes that change a lot are described as having a strong “evolution”.
How to test like a professional
- Spray once on a wrist or a paper strip.
- Smell immediately, then at 15 minutes, 1 hour and 4 hours.
- Write one or two words each time.
- Decide only after the dry down: that is what you will smell most of the day.
