A Journey into The World of Oud

Introduced in the Spring of 2015

Latest revision: July 2021

Part One

One of my favorite experiences so far in my aromatherapy explorations was visiting Kurt Schnaubelt, who not only introduced me to a wide variety of oils, but also got me interested in the rare and magical oil called Agarwood, Aloes, or Oud.

At the end of my visit with him, I just happened to ask him what turned out to be the most fortuitous question, "What is your next project?" He casually mentioned that one of his future ventures will be to create a collection of agarwood oils from different regions of Southeast Asia.

I asked him "what is agarwood oil", and he shared that it's a consciousness-altering essential oil that has been valued for thousands of years but is little-known in the West.

Having my curiosity aroused, I began my many-year-long journey exploring this amazing oil.

What is the origin of Oud?

(I have read a lot about Oud since I first wrote this column, and have recently revised it in order to increase its accuracy and depth).

When subtropical evergreen trees of two different genuses, Aquilaria and Gyrinops, suffer injury and then get infected by specific fungus, a small percentage of them exude a resin to protect themselves. It is the resin that is highly prized for its aromatic and spiritual qualities.

Agarwood oil or Oud (or Oudh) is currently available from two sources: the rapidly-becoming-extinct wild trees, and the sustainably farmed and manually infected trees. Unfortunately, in the wild, most trees are cut down en masse (even though 85% of them have no resin content) in order to harvest the oil.

The most reverential and respectful methods of harvesting Oud from trees in the wild are to either only harvest from trees that have already died, or to just remove only the resin-saturated infected parts of the trees, leaving the trees to continue to grow and thrive. I have been very happy to discover a few oils obtained by these methods.

Most Oud is prepared by steam or hydro-distillation of the pulverized wood, but some Oud is now being made using CO2 extraction (a cold method that extracts more of the constituents of the plant). (I recently found a company that has two oils created using vacuum distillation.)

(Ensar Oud points out that the production of "synthetic Oud", a mix of various chemicals some of which are toxic, has grown considerably in the perfume industry. Even some Oud purveyors are selling synthetic Oud as the real thing.)

What does Oudh smell like?

Lower grade Oud -- if the wood is soaked for weeks before distilling, often in unclean water -- can have a one-dimensional barnyard or fecal or animalistic smell; or in the case of many plantation Ouds harvested from too-young trees and not aged, have an overly sweet and floral and fruity scent that is also one dimensional and a little cloying.

The better Ouds are distilled carefully from older trees and then aged, and have a much fuller and rounder aroma and in fact offer so many different scents that each one is an exploration in itself.

Important Note: Dorje123 pointed out, on the Basenotes.net forum, that there are two very different kinds of barnyard, and some excellent Ouds have a barnyard component. To quote him:

"I think in a good oud the barnyard is balanced with other very rich notes, especially extreme "oudniness". And, the barnyard should dissipate into a woody-incense kind of note after a time, leaving a very rich, incense, sweet, maybe slightly fruity and intense smell that remains for a long time. Also, it would be marked by the absence of other "off-notes" after the barnyard fades away."

Oud is used in many high-end perfumes because of its complexity and versatility. In perfumery, scents are described as top-notes, middle-notes, and base-notes. Top notes are what you smell first, and represent the most volatile components of any oil. Middle notes form the central body of the fragrance, while base notes "fix" the fragrance (make it last longer) and are sometimes called the "dry down" scent, because they are the final scents that remain.

Therefore, when one applies Oud to oneself, there are a medley of notes to be experienced. Some Ouds don't vary much from beginning to end, while others vary tremendously.

For example, I recently got an Oud from India that was very pungent and intensely animalic in odor, and I thought that I would never sample it again. But I tried wearing a very small amount of it, and after a while (after both the top and middle notes were done), I was surprised by the sweetly floral dry down.

Among the scents found in agarwood oils are:

Floral: chamomile, lilac, rose, etc. (Typically found in Cambodian and Thai Oud distilled in Copper.)

Green: Grassy, herbaceous, minty, mossy. (Typically found in Borneo and Papua New Guinea Oud and other areas of Indonesia.)

Earthy: Dirt, mud, soggy wood, mildewy, hay. (Typically found in Candan Oud.)

Pungent: Barnyard, fecal, animalic, musky, funky. (Typically Indian Oud that has been soaked for a long time before distillation.)

Dark: Tobacco, leather, smoky, bitter. (Typically Indian, Indonesian, and Bhuntan Oud.)

Incense: Burned incense and wood, powdery, frankincense, heated resin (Typically from the highest grade and oldest wild trees).

Ice: Phenolic, crystalline, mineral (Found in Indonesian Ouds.).

Sweet: Perfumey, syrupy, vanilla, honey. (Typically in Copper distilled Cambodian and Thai Oud.)

Fruity: Orange, lemon, berries, raisins. (Typically found in Cambodian and Thai Oud.)

Spicy: Cinnamon, nutmeg, black pepper.

Balsamic: Resinous, soothing, syrupy, amber, balsam. (Found in both Thai and Cambodian Ouds.)

Syrup: Caramel, vanilla, maple syrup, sweet resin. (Found in the most refined CO2 extracted Ouds.)

Note: The species of wood used, the method presoaking (short/long, type and quality of the water used, additions to the water), the method of distillation (steam or hydro), the length of distillation and the temperature(s) used, the vessel used for the distillation (copper, stainless steel, hybrids, etc.), all alter the scent characteristics of the Oud produced. Oud can easily be ruined by mishandling, or made really special in the hands of a master distiller.

I originally preferred the sweeter, more floral and fruity Ouds, but over time I've graduated to prefer a much wider range of scents.

Acquiring Ouds

Note: You might want to jump now to my new web page which covers How to Approach Oud/Agarwood oil and Where to Start in Collecting Oud.

----------------------------------------------------------------------------------

I've explored many Ouds already. Some are low-priced, others are medium-priced, and several are very high-priced.

For Beginners:

Important Note: Aloes of Ish has gone out of business. I am only keeping this section on my website as a remembrance.

At the start of my Oud explorations, I found one purveyor who sold Oudhs at amazingly low prices:

Aloes of Ish


Labeled AA or A or HQ, his oil are so low priced because most of the Ouds he sells are second distillations. I.e. they are produced after the high-end Ouds have already been extracted. This makes them quite a bit less concentrated and more perfumey, and notably shorter-lived in the persistence of their scent, but for beginners they provide an affordable start.

Ish does sometimes have first-distillation AAA Ouds for sale, which are better, but they are bit more expensive, and you have to contact him to find out if he has any currently available.

Important note: When searching for Ouds, be careful NOT to purchase Mukhallats. These are blends of a little Oud with many other fragrance oils and are not pure agarwood oil.
