Oud

The word "oud" is the Arabic ʿūd — literally "wood" — used in perfumery as shorthand for agarwood, the dark resinous heartwood that certain Aquilaria trees produce only when infected with a specific mold. Healthy Aquilaria is pale and unscented; the resin forms as a defense response, which is why wild oud is rare enough that Aquilaria malaccensis is now critically endangered and trade is governed by CITES. India's April 2024 quota allows roughly 7 metric tons of agarwood oil annually for legal export — for a global fragrance industry the same fraction sees as a rounding error. The chemistry is dominated by oxygenated sesquiterpenes and chromones (agarospirol, jinkohol, jinkoh-eremol), but the smokier ouds also carry traces of the same molecules you would find in old leather and aged whisky barrels.

The note arrives in Western perfumery early — Yves Saint Laurent's M7 (2002) is the often-cited modern beachhead — but the 2007 release of Tom Ford Oud Wood is what turned oud into a Western commercial category. What Tom Ford did was smooth: cardamom and rosewood up top, sandalwood underneath, a polished oud accord in the middle, none of the barnyard. A decade of designer oud-and-rose flankers followed; by the late 2010s the note had been gourmandized (Mancera's Red Tobacco, Xerjoff Alexandria II), incense-ified (Amouage Interlude Man), and made into amber-radiant blockbusters (Louis Vuitton Ombre Nomade, 2018). Outliers exist — Creed Royal Oud (2011) treats it as a clean base support rather than a centerpiece — but across the catalog, just under fourteen thousand fragrances now list oud as a note, a scale that arrived in roughly fifteen years.

Most fragrances labeled oud today contain little or no natural agarwood oil. The label functions more like a stylistic flag — dark, rich, Middle Eastern-inflected — than a guarantee of material. That is not necessarily a problem; the best synthetic oud bases (Norlimbanol, Karanal, the proprietary oud-naphtha accords the big houses guard) are extraordinary perfumery ingredients on their own merits. But it explains why oud fragrances vary so wildly. A Creed-style fresh oud, a Nasomatto barnyard bomb, and a Memo leather-oud are all named after the same word and share almost no common ground. Treat oud as a starting hypothesis to be confirmed by sample, not a finished claim.
