What Is Oud? A Guide to Liquid Gold

Called liquid gold for good reason, oud is one of the most precious materials in perfumery. A short guide to where it comes from, how it smells and how to recognise quality.

Few ingredients carry the weight of history that oud does. Burned in palaces and places of worship across the Middle East and Asia for centuries, it has earned a nickname that is not an exaggeration: liquid gold.

Where oud comes from

Oud — also called agarwood — comes from the Aquilaria tree. Healthy wood is pale and almost odourless. Only when the tree is wounded and infected does it produce a dark, aromatic resin as a defence. That resin-soaked heartwood is harvested, then either burned as chips or distilled into precious oud oil.

How oud smells

Oud is not one scent but a spectrum. Depending on its origin and age, it can be woody, smoky, leathery, balsamic, sweet or even slightly animalic. The finest grades are smooth and layered, unfolding differently on every skin.

“Great oud does not shout. It reveals itself slowly, one layer at a time.”

Recognising quality

Quality oud is defined by depth and longevity. It should evolve on the skin rather than stay flat, feel rich rather than sharp, and remain present long after lighter notes have gone. Age matters too: like fine wine, oud oil matures and softens over time.

Every TORAX fragrance is built around this material — with the rarest grade, Kinam, at its core.
