Every fragrance is sold with a pyramid: top notes, heart notes, base notes, each a short list of recognisable things. Bergamot, jasmine, sandalwood. It is a useful fiction and it is worth understanding exactly which parts of it are fictional.
The list is written by a marketing department, not by the perfumer, and it describes an impression rather than a formula. There may be no jasmine in a fragrance whose heart is listed as jasmine — jasmine absolute is expensive and its dominant character can be built from hedione, benzyl acetate and a few other materials at a fraction of the cost. That is not a scandal; it is how the industry has worked for a century, and some of the most admired compositions in existence are almost entirely synthetic.
What it means practically is that reading note lists teaches you very little about whether you will like something.
What to learn instead
Accords. An accord is a blended effect built from several materials that reads as a single thing, and it is the actual unit of perfume composition. There are perhaps fifteen you need to recognise, and knowing eight of them will change how you shop.
The fresh-clean accord: aldehydes, white musks and a citrus top, which is what most people mean by “clean laundry”. The gourmand: vanillin, ethyl maltol, tonka, often with a coffee or caramel facet. The woody-amber: labdanum, benzoin, cedar and one of the modern amber molecules, which is the backbone of about half of everything released in the last fifteen years.
Then the ones people identify by mistake. Iris, which reads as cold, powdery and faintly carroty and is frequently described as “expensive”. Fig, which is green, milky and slightly coconut. Ambroxan, which is the salty-skin note that launched a thousand “smells like nothing but better” reviews. And oud, which outside of a few genuine attars is almost always a synthetic leather-medicinal accord.
Learn to name those and you can walk into a shop knowing what to ask for.
How to actually test
Three at a time, maximum, and never on card. Card tells you about the top notes and nothing about the way a composition behaves on warm skin — which is the only thing that matters, since you are going to be wearing it there.
Give each one four hours. Most compositions change character twice: once as the top notes burn off in the first fifteen minutes, and once as the heart resolves into the base around the two-hour mark. The two-hour version is the one you will smell for the rest of the day, and a great many purchases are made on the fifteen-minute version.
Between tests, smell your own forearm rather than coffee beans. Anosmia to a fragrance you have been smelling for five minutes is normal and recovers in a minute or two; coffee beans do nothing for it beyond giving your nose something else to be fatigued by.
The one shortcut that works
Find a fragrance you already love and look up who composed it. Perfumers have signatures — a preference for particular materials, a way of building a base — and following a nose is a far better predictor than following a brand, a note list, or anything written on the box.
It is also the only piece of information in the whole industry that nobody has an incentive to embellish.
