Essential Oil Scent Families: Where Fragrance Wheels Disagree
A scent family says what an oil smells like; a note position says how long it lasts. They are different questions, and most "essential oil scent wheel" pages blur them. The best-known fragrance wheel also sorts finished perfumes, not raw essential oils, so placing an oil on it is an extrapolation, and the published systems do not even agree on how many families there are.

The wheel most people mean is Michael Edwards's Fragrance Wheel, first published in his 1992 book Fragrances of the World. It is a descendant of earlier diagrams: Paul Jellinek's 1949 odor effects diagram and a 1979 "Fragrance Circle" from Haarmann & Reimer. In the 2010 version described on Wikipedia's page, the families are Floral, Amber, Woods, Fresh and Fruity, each split into subfamilies, and adjacent families are presumed to share olfactory traits. The same page describes older versions with Fougère at the centre and "Oriental" where Amber now stands, and it lists four primary families in its text and five in its table, a reminder that even summaries of one wheel differ (Wikipedia, Fragrance wheel, read October 2026).
A second system comes from French perfumery. According to the fragrance trade site Osmoz, the first "Classification of Perfumes" was created in 1984 by the Technical Commission of the French Society of Perfumers, and it names seven families: amber (oriental), woody, chypre, leather, citrus, floral and fougère (Osmoz, 2015). Chypre and fougère are families defined by an accord, not by a single smell: Osmoz describes chypre as built on oakmoss with floral and fruity notes, after Coty's 1917 perfume of that name, and fougère as a blend of woody and lavender notes.
| System | Families | Built for |
|---|---|---|
| Edwards Fragrance Wheel (2010 version, as summarized on Wikipedia) | Floral, Amber, Woods, Fresh, Fruity (subfamilies such as Aromatic, Citrus, Water, Green, Mossy Woods, Dry Woods) | Helping retailers and consumers place finished perfumes |
| French Society of Perfumers, 1984 (as described by Osmoz) | Amber, woody, chypre, leather, citrus, floral, fougère | Classifying perfumes by composition |
Neither system was drawn for essential oils. That does not make them useless for a home blender, but it means every placement below is our reasoning from the cited tables, not something either system states.
The same oil lands in different families
The Good Scents Company, a widely used perfumery materials database, assigns each material an "odor type" and lists substantivity in hours without stating how the figure was measured, so treat the hours as one database's numbers. Set beside the example notes in the Edwards table summarized on Wikipedia (Fresh: lavender, bergamot; Woods: vetiver; Amber: sandalwood, patchouli; Floral: fresh-cut flowers), you can see where the systems disagree.
| Oil | Database odor type and descriptors | Listed substantivity | Edwards-style placement (our reading) |
|---|---|---|---|
| Lavender, France | Floral; herbal, floral, spicy, aromatic, camphoreous, balsamic, woody | 12 hours | Fresh (aromatic); fougère in the French system |
| Rose, Bulgaria | Floral; rose, spicy, winey, waxy, honey, green | 168 hours | Floral |
| Patchouli | Woody; old wood, dry, earthy, balsamic, spicy, minty | 400 hours | Amber (the table lists patchouli there), though the database says woody |
| Vetiver, Haiti | Woody; earthy, rooty, balsam, amber | 400 hours | Woods |
| Cedarwood, Virginia | Woody; cedar, oily, balsam | 388 hours | Woods |
| Amyris wood oil | Balsamic; sweet, balsam, peppery, guaiacwood, cubeb | 400 hours | Between Woods and Amber |
| Amyris bark oil | Woody; sweet, creamy, sandalwood, blackcurrant, smoky | Not listed | Between Woods and Amber |
Three things stand out. Lavender is a "floral" in the database, an "aromatic" under Fresh in the Edwards-style table, and the defining note of the fougère family in the French list. Patchouli is "woody" in one place and an amber material in another. And amyris itself has two database entries with different descriptors because the database separates wood oil from bark oil; both place it near the sandalwood group, and the database's sandalwood page lists amyris among its primary sandalwood-like materials (The Good Scents Company, sandalwood odor page). Since the Edwards-style table files sandalwood under Amber and vetiver under Woods, amyris sits across a boundary, which is our reasoning from those two tables. The CAS number 8015-65-4 is the same on both entries and on our Certificate of Analysis, which describes the smell as woody, earthy and smoky; our own shop description is creamy, woody and balsamic with a soft vanilla undertone.
Families loosely predict how long a scent lasts
If family and note position were independent, a wheel would tell you nothing about longevity. They are not independent. In a 2013 paper in Sensors, Manuel Zarzo compared perceptual freshness ratings for perfumery materials with tenacity values from the literature and reported a strong negative correlation, r = -0.85, between fresh odor character and substantivity; perfumers generally regard citrus and green notes as fresh and fast-evaporating, and oriental, powdery and animalic scents as long-lasting (Zarzo, 2013). The table above follows that pattern: lavender at 12 hours, rose at 168, the woods at close to 400. It is a trend across many materials, not a rule for every oil.
The practical consequence, reasoning from that paper, is that a blend assembled only from the Fresh family will start bright and lose its shape quickly, while a blend of woods and ambers changes slowly. Our shop copy describes amyris as a base note that helps citrus and floral top notes hold, which is how we would use it: as the member of the blend that stays.
How to use families when you blend
The only claim the wheel makes that is useful to a blender is that neighbours are related: Edwards-style wheels are drawn so that adjacent groups share olfactory traits. Reasoning from that, a first blend should pair two neighbours (a Fresh citrus with a Woods material, say) before attempting a blend from opposite sides of the wheel, and each change should be made one at a time so you know which oil moved the smell. For the full method see how to blend essential oils, and for how amyris pairs with citrus, spice and floral oils, blending amyris with citrus, spice and floral oils. If your question is which woody oil to buy, woody essential oils compared goes through the woods in one place, and base note essential oils covers tenacity.
What a scent family cannot tell you
A family is a statement about smell. It carries no information on skin safety, quality or identity: the citrus family includes expressed oils with phototoxic furanocoumarins and distilled oils without them (Tisserand Institute, phototoxicity, read October 2026). Check the dilution and safety of each oil separately; the essential oil safety guide is the place to start. The substantivity figures above come with no stated method, and descriptors are a matter of whoever did the smelling, so use the table as a map of disagreement, not a measurement.
If you came here to decide whether amyris belongs with sandalwood, the family tables do not settle it; they only show that it sits on the sandalwood boundary, which is not the same as being sandalwood. We do not describe our oil as sandalwood. For the difference see amyris versus sandalwood oil, and for what our oil smells like on its own, what amyris essential oil smells like.
