Oud begins as a wound. When certain trees of the Aquilaria genus are infected by a mould, they defend themselves by producing a dark, fragrant resin. Over years, the heartwood darkens and becomes agarwood, one of the most precious raw materials in perfumery.
Across the Gulf it has been part of daily life for centuries. Chips of agarwood are burned as bakhoor to scent homes and clothes, and the oil, dense and smoky, is worn alone, a drop at the wrist or behind the ear.
Oud does not sit on the skin. It settles into it.
Western perfume houses came to it late, and their early attempts often used synthetic versions that captured the smoke but not the depth. Over the past two decades, as perfumers spent more time with the real thing, their compositions have grown more confident, pairing oud with rose, saffron and leather in ways that owe a clear debt to the region.
Real oud remains rare and expensive, and quality varies enormously. The best advice is the oldest: try it on skin, wait an hour, and judge it by how it smells at the end of the day rather than the beginning.
