Pyramid
Base
Dark, complex, animalic-woody with a fermented, almost barnyard depth. Oud smells like nothing else — leather soaked in honey, left in a smoky temple, then buried in wet earth.
Intensely complex. Opens smoky, leathery, animalic — almost barnyardish in Hindi varieties. Cambodian types are sweeter, with dried-fruit and caramel qualities. All share a deep, woody-resinous backbone with medicinal, bitter undertones. More animalic than sandalwood, darker than patchouli, less clean than cedarwood. The dry-down is warm, persistent, and deeply woody — oud can last days on skin and weeks on fabric.

The Full Story
Essential oil distilled from the resinous heartwood of Aquilaria trees (primarily A. malaccensis, A. crassna, A. sinensis) infected by Phialophora parasitica mold. The infection triggers a defensive resin production — agarwood — which transforms the pale, odorless wood into dark, fragrant, extraordinarily valuable material.
Oud oil is arguably the most complex and polarizing material in perfumery. Its scent ranges wildly by origin: Cambodi oud (Cambodia) tends to be sweet, fruity, almost caramelized. Hindi oud (India, Assam) is dark, animalic, leathery, almost fecal at high concentration. Malinau/Borneo oud is greener, more herbal. The chemistry is dominated by sesquiterpenes (agarospirol, jinkoh-eremol) and chromone derivatives — hundreds of volatile compounds have been identified.
In Western perfumery, oud has been the defining trend ingredient of the 2010s-2020s. Most 'oud' fragrances use synthetic reconstructions (a major aroma-chemical supplier's Oud Synthetic, a Swiss fragrance house's Agarwood Base) rather than natural oil, which can cost $20,000-100,000+ per kilogram for high-quality material.
A single kilogram of high-grade wild Hindi oud oil has sold for over $100,000, making it more expensive per gram than gold. The most prized agarwood — 'sinking grade' or 'chen xiang' (沉香) — is dense enough to sink in water, indicating complete resinous saturation of the wood fibers.
Extraction & Chemistry
Extraction method: Steam distillation or hydrodistillation of infected agarwood chips, typically over 48-72 hours. Yield is extremely low — approximately 0.1-0.7% depending on resin density. CO2 extraction captures a different, often smoother profile. The raw material itself is the bottleneck: natural infection rates are very low (perhaps 7-10% of wild trees), and plantation inoculation techniques produce variable results. Major producing countries include India (Assam), Cambodia, Vietnam, Laos, and Indonesia.
Base note and signature ingredient in amber, woody-ambery, and Middle Eastern compositions. Natural oud functions as both a character note and a powerful fixative. In traditional Arabian perfumery (mukhallat), oud is the central element. In Western perfumery, synthetic oud bases are used to provide the dark, woody-animalic character at accessible price points. Oud pairs with rose (the classic Arabian combination), saffron, sandalwood, and amber.
