Understanding Oudh: Why It's the Most Prized Note in Perfumery
Oudh — also written oud, and known as agarwood — is the most expensive raw material in mainstream perfumery, and the one most often misunderstood. If you have ever found it overwhelming, or wondered why a small bottle costs what it does, the explanation is in how it forms.
What oudh actually is
Oudh is not a wood in the ordinary sense. It is resin. Aquilaria trees, when their heartwood is infected by a particular mould, defend themselves by saturating the affected wood with a dark, dense, aromatic resin. That resinous heartwood is agarwood. An uninfected tree produces none of it.
This is why oudh is scarce: the process is a response to injury, it takes years, and only a fraction of trees produce resin worth distilling. Scarcity, not marketing, sets the price.
What it smells like
Oudh is not one smell. Depending on origin, age and distillation it can read as sweet and honeyed, leathery and animalic, smoky and medicinal, or warm and balsamic — often several of these in sequence on the skin. What stays constant is depth. Oudh sits low in a composition and lasts, which is why perfumers use it as a base note (see our guide to fragrance notes).
How to wear it
The single most common mistake with oudh is applying too much. It is a concentrated, tenacious material and rewards restraint.
- Start with one application at a pulse point and wait. Oudh grows on the skin over the first half hour rather than announcing itself immediately.
- Cooler weather suits it. Heat amplifies an already powerful note; in Indian summer, less is genuinely more.
- Evening over morning. Oudh has presence — most people find it easier to wear after dark, or in formal and celebratory settings.
- Do not layer it with another heavy base. Oudh does not need help.
Oudh in India
Oudh has a long history across South Asia and the Gulf, worn both as an attar and burned as incense. That heritage is one reason Indian fragrance buyers often have a more educated relationship with oudh than markets where it arrived recently as a luxury trend.
Trying it
Oudh is the note most worth testing on your own skin before committing, because its development varies so much from person to person. Our Oudh Highness is a 60ml eau de parfum built around agarwood character — and like every 60ml signature perfume, it ships with a complimentary discovery sample of another SPR scent.
