Why this wheel is built differently
400+ raw materials, not finished perfumes — and a second
dimension no other wheel has: distance from the centre is how long a material
lasts.
The wheel everyone knows was drawn by Michael Edwards in 1983 and it is a good piece of
work — for its purpose. Its purpose is helping somebody in a shop understand the
bottle in their hand. It classifies finished perfumes into four families and fourteen
sub-families, and it is arranged so that neighbours blend into one another.
It has four well-known problems, and a perfumer runs into all of them.
| The complaint | What is actually wrong |
|---|
| No chypre | The structure is scattered across Mossy Woods and Woody Amber, which loses the thing that makes a chypre a chypre. |
| No fougère | Absorbed into "Aromatic", despite being the shape of roughly two in five masculine fragrances. |
| No gourmand | The fastest-growing category in perfumery, filed under Amber — which catches the warmth and misses the point. |
| "Oriental" | Carried for nearly forty years before being renamed Amber in 2021. |
But the deepest problem is not any of those. It is that a wheel of finished perfumes is
the wrong object for somebody who makes them. You cannot buy a bottle of "Woody
Oriental". You buy vetiver, and Iso E Super, and labdanum, and the wheel has nothing to
say about any of them.
What is different here
1 · It plots materials, not perfumes. Every dot is a thing you can order,
weigh and put on a blotter.
2 · The radius means something. This is the change that matters. Every
published wheel is flat: position tells you what a thing smells of and nothing
else. Here, distance from the centre is tenacity — materials near the rim are
gone in an hour or two, materials near the middle are still there the next morning. Two
dotted rings mark two hours and twenty-four.
Which means a formula plotted on this wheel is its own structure, drawn. All your
dots clustered at the rim and you can see, before you weigh anything, that there is nothing
underneath to hold it up.
3 · The sectors are sized honestly. Every other wheel gives each family an
equal slice, which quietly implies the world is evenly divided. It is not. Florals take
almost a quarter of the arc here because florals are almost a quarter of a working palette.
Mossy takes a sliver, because after the oakmoss restrictions there is a sliver left.
4 · The missing structures are on it. Chypre, fougère, gourmand and
cologne are not families of smell — they are architectures, and they draw across
several sectors at once. Rather than pretend they are wedges, the wheel lights up the
regions each one borrows from. That is the honest answer to the criticism, and it is only
possible because the wheel is made of data rather than drawn once by hand.
5 · Naturals and synthetics are visibly different. One glance tells you that
the green sector is mostly naturals and the musk sector is almost entirely not —
which is a fact about perfumery that no consumer wheel has any reason to show you.
What it is not
It is not a replacement for smelling things, and it is not a claim that the boundaries are
real. Families are a convenience; plenty of materials sit honestly in two of them, and the
one chosen here is the one a perfumer would reach for it under. Read it as a map of a
territory, drawn by someone who has walked some of it — not as the territory.
