Say "woody perfume" and many people picture something heavy and smoky. Some are. But two of the best-known "woods" aren't wood at all: vetiver is a root and patchouli is a leaf.
The short version
- Woods fade more slowly than citrus, so judge a woody scent once it settles on your skin.
- Start with texture: sandalwood is creamy, cedar pencil-like, vetiver earthy, patchouli spicy and oud resinous.
- Notes describe the smell, not what's in the bottle, so ask the brand if the source matters.
Where woody sits on the fragrance wheel
Michael Edwards' Fragrance Wheel sorts perfumes into four families: fresh, floral, amber and woody.
Woody splits three ways:
- Woods: cedar, sandalwood, vetiver, patchouli and pine.
- Mossy woods: oakmoss and patchouli with amber and citrus.
- Dry woods: leather and tobacco give a dry, often smoky edge.
Woody's neighbours are woody amber and the aromatic family.
Why woods last longer than citrus
A perfume doesn't evaporate in tidy stages. It all starts at once, at speeds set by vapour pressure: how readily each molecule escapes into the air.
Small, light molecules tend to escape faster than big, heavy ones. Citrus smells come mostly from small ones like limonene, which has 10 carbon atoms. It's the first thing you smell and the first to go.
Most woody smells come from sesquiterpenoids, which have 15 carbon atoms. They're heavier, so they leave the skin slowly.
That's why perfumers use woods as base notes. They often work as fixatives too, helping lighter notes last longer.
How the smell gets out of the plant
Most woody oils are made by steam distillation:
- Steam passes through chipped wood, roots or dried leaves and carries the scent out.
- It then cools in a condenser.
- The oil doesn't mix with water, so it forms a layer that's drawn off.
Patchouli leaves are usually dried, and sometimes fermented, first. This helps release more oil.
The main woody materials
Sandalwood, cedar and guaiac oils come from the wood. Vetiver comes from roots, patchouli from leaves, and oud from resin.
Sandalwood: soft and creamy
Sandalwood oil is distilled from the heartwood (the trunk's inner core) of Santalum album, the Indian sandalwood tree. It smells warm, sweet and creamy.
Most of that comes from two related molecules, alpha-santalol and beta-santalol. The oil is valued mainly on how much of them it has.
Wild Indian sandalwood was cut so heavily that it's now listed as vulnerable on the IUCN Red List. A tree takes decades to grow heartwood worth harvesting, so supply can't recover quickly. Plantations, especially in Australia, now grow it.
Cedarwood: the pencil-case wood
The best-known cedarwood oils, Virginian and Texan, come from junipers, not true cedars. Their woody smell comes mainly from sesquiterpenoids, chiefly thujopsene, cedrol and the cedrenes.
Virginian red cedar was once the main wood for pencils. That's why it's still sometimes called pencil cedar.
Vetiver: earthy roots
Vetiver is a tall tropical grass, and its oil comes from the roots. It smells earthy and woody, and it's often used as a fixative. Haiti is the best-known source.
The oil has hundreds of compounds, khusimol among the most plentiful. But in 2021, chemists showed that its classic woody, ambery smell comes mainly from a compound found only in traces. It's called (+)-2-epi-ziza-6(13)en-3-one.
Patchouli: woody, spicy leaves
Patchouli is a leafy plant in the mint family, grown across tropical Asia. Its oil smells woody and spicy.
The oil's main compound is patchoulol (patchouli alcohol). Quality is judged mainly on how much of it the oil has.
Guaiac wood: woody, with a hint of rose
Guaiac wood oil is distilled from the heartwood of Bulnesia sarmientoi, a tree of the Gran Chaco. That's the dry forest where Paraguay, Argentina and Bolivia meet.
The oil smells woody with a soft, rosy side. It's made mostly of sesquiterpenoids.
The tree has been on CITES Appendix II since 2010. So cross-border trade in its wood and oil needs permits.
Oud: the wood made by a wound
Oud, or agarwood, is fragrant, resin-filled wood from Aquilaria and related trees. A healthy tree doesn't make it. When a tree is wounded and fungi get in, it lays down resin around the damage as a defence.
That resin's smell comes mainly from sesquiterpenes and 2-(2-phenylethyl)chromones. Our guide to what oud smells like goes deeper.
One agarwood species has been on CITES Appendix II since 1995, and the others since 2004.
Lab-made woods
Many woody notes now come partly or wholly from lab-made aroma chemicals. Part of the appeal is that they don't rely on scarce wild sandalwood or ambergris.
- Iso E Super smells soft, woody and ambery. Much of that smell comes from a related compound present in the mix only as a small impurity.
- Ambroxan (ambroxide) is a key smell molecule of ambergris, a rare waxy substance from sperm whales. It's made from sclareol, found in clary sage, so no whale is needed. It's used as a musky base note.
Notes aren't ingredients
A "sandalwood" note might be natural, lab-made or a mix of both.
Under EU cosmetics rules, the whole fragrance blend can be listed as one word: "parfum". Only certain allergens are named. If the source matters to you, ask the brand.
What woods are paired with
- Spice. In woody amber, spicy amber notes are woven through patchouli, oud and sandalwood.
- Vanilla. It's a mainstay of the amber family next door, so it often meets woods.
- Flowers. In Kannauj, India, attars are still made by distilling rose, jasmine and other flowers straight into sandalwood oil.
- Citrus and herbs. Bergamot or lavender over woods gives the fresher aromatic style.
How to find the woods you like
Compare two at a time. A sandalwood-led scent next to a cedar-led one teaches you more than any notes list.
Then look at the partners. You may love the spice or vanilla as much as the wood.
Our guide to how perfume oils wear compares oils and sprays. For a flower to pair with woods, try our guide to jasmine.
From our shelves
To try woods with the partners above, start here. The first four are alcohol-free perfume oils, in a full-size bottle or 6 ml and 3 ml roll-ons, and each also comes as an Extrait de Parfum. They're described by their listed notes.
- Pure Reverie: bergamot and aromatic herbs over vetiver and cedarwood, with oud and amber in the base. Woods with citrus and herbs.
- Stellar Dreams: cinnamon, cardamom, orange blossom and bergamot, then Bourbon vanilla and elemi, over praline, ambroxan, guaiac wood and musk. Woods with spice and vanilla.
- Al Layl: saffron, lemongrass and white musk, then freesia and mandarin, over sandalwood and vanilla. Sandalwood with spice and vanilla.
- Luna Bliss: rose and oud, then vanilla, over white musk and frankincense. Woods with rose.
- The Oud Discovery Set: four of our oud and wood perfume oils (Imperial Wood Oud, Royal Bliss, Pure Reverie and Dark Passion) in 3 ml roll-ons, so you can compare them side by side.
You'll find more in our woody collection, our oud collection and our discovery sets.
