The ScentWheel
We measure what a perfume smells like. The ScentWheel reads a fragrance's real notes and plots them on eight axes - the same fingerprint that powers our similarity matching.

How the ScentWheel works
A perfume is a blend of notes. The ScentWheel turns that blend into a measured shape you can read at a glance - and compare.
We research every note
We have scored over 1,800 perfume notes on 28 fine-grained scent characters - things like citrus, powdery, smoky, leather and honeyed. Each note gets its own profile, so a real rose and a synthetic rose read differently when they smell different.
28 characters become 8 readable axes
Those 28 characters group into eight families you can actually read: Fresh & Citrus, Floral, Fruity, Green & Aromatic, Sweet & Gourmand, Spicy, Woody & Earthy, and Amber - Musk - Leather. The eight spokes of the wheel are those families. The 28 are still there underneath - flip to "28 characters" to see them.
Breadth - how sure we are
Some notes are precise (a sharp lemon). Others sprawl across many characters (oud, amber). We measure that spread too, and call it breadth. A precise note sits tight on the wheel; a sprawling one casts a wider halo - so the picture also shows how confident the read is.
The shape is the fingerprint
A perfume's wheel is the weighted blend of its notes. Two fragrances with the same shape smell alike - which is exactly how we find dupes and similar scents. We compare the shapes and surface the closest matches.
A family label ("woody") tells you one thing. The ScentWheel tells you how woody, how sweet, how fresh, and how sure we are - all at once, from the real composition. It is measured, not guessed, and the same perfume always makes the same wheel.
See it for yourself
Here is a live ScentWheel. Start with a single note to see its breadth - a focused note sits tight, a broad one opens a wide halo - then switch to a whole perfume to watch its notes blend into one shape. Toggle 8 axes for the big picture or 28 characters for the detail.
The drydown journey
A perfume is not one smell - it changes hour by hour as it dries down. The bright opening burns off, a heart settles in, and a base lingers on skin long after. To capture that, we research each note twice: not just what it smells like, but when it shows up and how long it lasts.
- When - every note is placed in a phase: the bright top, the heart, or the deep base.
- How long - every note carries a real lasting time, drawn from published odour-substantivity data, so we know roughly how many hours it stays on skin.
On any perfume page you can scrub the drydown and watch the ScentWheel morph from the opening through the heart to the base, with each note's presence laid out across the timeline above. The ScentWheel is not a single snapshot - it is the whole journey.
Most fragrance sites stop at a note pyramid - three fixed lists labelled top, heart and base. That tells you what is in the bottle, but not how it actually wears. Our drydown is measured: every note has a real onset and duration, so the ScentWheel moves through the wear instead of freezing it into three boxes.

How it relates to other systems
If you have seen a fragrance "wheel" before, it was probably Michael Edwards' Fragrance Wheel - the classic chart that sorts perfumes into families like Floral, Oriental, Woody and Fresh. It is a brilliant map, and our eight axes line up with that same intuition.
The ScentWheel takes the idea further. Edwards' wheel is hand-drawn and sorts a whole perfume into one family. Ours is measured from a perfume's real notes, finer-grained, per-fragrance, and it does real work: it powers live similarity. The wider field is moving the same way - towards computational olfaction, where scent is mapped as data (Google's Principal Odor Map is one well-known example). We have built our own corner of that for real bottles you can buy.
We have read the research and we respect the classics - but the exact recipe is ours: how we weight each note, measure breadth, and score a match is tuned and validated on thousands of perfumes. That is the part that makes the ScentWheel ours, and it is why our "smells similar" results are different from anyone else's.
Frequently asked questions
What is the ScentWheel?
The ScentWheel is our measured fingerprint for a fragrance. We score a perfume's real notes on 28 scent characters, group them into 8 readable axes, and plot the result as a wheel. It is the same data we use to find similar perfumes.
Is this AI-generated?
No. The ScentWheel is built by a fixed method from real composition data - the perfume's actual notes and their researched profiles. The same perfume always produces the same wheel. It is measured, not invented.
What does "breadth" mean?
Breadth is how wide or precise a note is. A sharp lemon is narrow; oud or amber spreads across many characters. We measure that spread and show it as a halo, so the wheel also tells you how confident the read is.
How is it different from the Fragrance Wheel?
Michael Edwards' Fragrance Wheel is a hand-drawn family map for whole perfumes. The ScentWheel is measured from each fragrance's real notes, finer-grained, and it powers live similarity matching rather than just labelling.
Can I see it on any perfume?
Yes. Every published perfume on ScentVerdict has its own ScentWheel in the Profile section, with a scrubable drydown. Browse all perfumes to explore.
How accurate is it?
It is grounded in researched note data and validated against thousands of community-named dupes and "reminds me of" pairs. No scent model is perfect - smell is personal and perfumes are complex - but the ScentWheel gives a consistent, honest read you can compare across fragrances.
