Oud (also called agarwood) is a rich, woody, resinous scent derived from the dark, fragrant heartwood that forms when Aquilaria trees become infected with a particular mould. Prized for centuries in the Middle East, real oud is one of the most expensive raw materials in perfumery.
What oud smells like
Oud is deep, warm and woody with smoky, leathery, sweet and sometimes animalic or 'barnyard' facets. Quality and origin vary enormously — Cambodian oud leans sweeter and fruitier, Hindi oud more intense and animalic. In Western perfumery, oud is often softened and paired with rose, saffron or amber to make it more wearable.
Where it comes from
Oud forms inside Aquilaria trees in South and Southeast Asia (Cambodia, India, Laos, Thailand) when the heartwood reacts to a specific mould infection, producing a dark, fragrant resin. Because only some trees become infected and the process takes years, natural oud is rare — hence its nickname 'liquid gold'.
Why oud is so expensive
Wild Aquilaria is endangered and the resin-forming process is slow and unpredictable, making genuine oud extraordinarily costly — among the priciest natural materials in perfumery. Most affordable 'oud' fragrances use synthetic oud accords, which are excellent, consistent and sustainable alternatives to the real thing.
Oud in fragrance culture
Oud is the cornerstone of Gulf and Middle Eastern perfumery, worn generously and layered with bakhoor (scented wood chips). Houses like Amouage, and the wave of accessible brands like Lattafa, Ajmal and Al Haramain, have brought oud to a global audience.
Oud smells deep, warm and woody with smoky, leathery and sometimes sweet or animalic facets. Cambodian oud is sweeter and fruitier; Hindi oud is more intense. It's often paired with rose, saffron or amber in perfume.
Why is oud so expensive?
Genuine oud comes from the rare, slow-forming resin inside infected Aquilaria trees, which are endangered. The scarcity and unpredictable formation make it one of the most expensive natural materials in perfumery — hence 'liquid gold'.
Is oud in perfume natural or synthetic?
Both. Real oud is extremely expensive, so most affordable oud fragrances use synthetic oud accords — high-quality, consistent and sustainable alternatives that capture the character without the cost.
