Types of Oud: The Names Are Ports, Not Trees

Hindi, Cambodi and Borneo name ports, not trees. A taxonomy of oud: the Aquilaria and Gyrinops species behind each region, why the barnyard note is mostly a distiller's decision, how kyara grading works, and what CITES actually restricts.

Everything you smell as oud is an injury.

Agarwood is not a kind of wood. It is what forms inside a living tree wounded and colonised by microbes, resin laid down over years of damage. Uninfected heartwood is pale and odourless.

Nobody grows oud. They grow harm. Every word on an oud label describes how the harm was made, moved and sold.

The names are ports

Hindi, Cambodi, Borneo, Trat. They read like different trees. Almost none are. Sri Lankan oud and Indian oud are not even the same genus.

These names are shipping geography, not botany. Borneo alone covers three different trees sold under one island's name.

One bottle holds the spread: Blue Kalbar sets Sri Lankan and East Indian oud side by side, one earthy, one darkly resinous, settling into civet and ambergris over Mysore sandalwood. Moderate sillage, 8 to 10 hours.

The barnyard is a decision

The famous Hindi funk, the farmyard blast people either chase or flee, is largely not decided by the tree. It is decided at the soaking basin.

Before distillation the chipped wood soaks in water, a few days to three months, and that slow fermentation writes the sour, animal character into the oil. That is why one region gives a clean oil in one shed and a barnyard one in the next. You are not smelling India. You are smelling how patient the distiller was.

A filthy, unsupervised soak gives a fecal oil. Good wood soaked and distilled clean gives the barnyard collectors chase.

The arithmetic is brutal either way: seventy kilograms of wood yields at most 20 millilitres of oil.

The animal rose: Oud Maximus, Laotian, Indian and Thai oud worked into four rose oils, the Laotian oud animal from the first minute, birch tar underneath. Strong, 8 to 10 hours.

The clean, sweet exit: Borneo Trifecta, a tropical greenhouse of honeysuckle, jasmine and rose over Mysore sandalwood. Its pyramid, honestly, names Malayan and Papua oud, nothing literally Bornean. Moderate, 4 to 6 hours.

Everything you smell as oud is an injury that went on for years.

Kyara is a grade, not a tree

Kyara, the summit of the Japanese incense system, sounds like the rarest tree on earth. DNA work on 58 farmed Qi-Nan trees, the same top grade under its Chinese name, placed every one inside a single ordinary species.

In China, Qi-Nan is now propagated by grafting and grown in plantations. The kyara of Japanese incense came from wild trees, most of it from Vietnam, and wild kyara-grade wood still turns up in Brunei, Cambodia and Hainan.

If you only try one from this shelf: Kyara de Kalbar, Brunei, Kyara and Malayan ouds opened by crushed black grape, raspberry and persimmon. Strong, 8 to 10 hours.

The one that will not come back: Through the Looking Glass, carrying purple kinam, the Vietnamese word for the same grade, with wild Bornean agarwood under plum blossom and Iranian rose otto. It is the last of the Folkwinds Wonderland perfumes, ended by material discontinuations.

Why most oud is not oud

Every agarwood tree has been CITES listed since 2005, and the most traded species has lost over 80 percent of its population in three generations. That is the number under every price tag.

It is also why most commercial oud is a lab reconstruction, and no rule says it cannot be. A note pyramid describes an intended effect, not the contents. Black Afgano wears the note at Enormous sillage for 10 to 12 hours, and we make no claim about what is inside it, having no source.

None of this is scandal. It is what the words mean. Now that you can read them, the oud decant guide is the shopping list.
