Perfumer’s Nose: Oud, The Nuances

Deep Earth Scent Vision

The second time around I switch the order of the oud samples. For my first sniffing trial, I randomly lined up my little sample vials which were all diluted to 10%. The dilute samples on the scent strips yield the nuances in different ways as the fragrance dries out. A few things happen as I go through the samples, mainly I confirmed that evaluating oud is a learned skill and that I could probably go through these few samples many more times and get something different each time. But I also found that some aspects come through whether it is the first sample of the day or the last sample.

I like to think I have a well-trained nose but I have known all along that the determined character of agarwood essential oils would put my nose to the test. Which happened. What also happened was that I walked around with the smell of oud in my nose – kind of a nice effect that fragranced the world around me. But it also limited any other evaluations I could conduct for at least a day.

It won’t be surprising that the more subtle aspects of fruit and fine wood are lost as your nose becomes a bit overloaded with oud. I did pretty well the first time through, picking up nuances of woody notes, spice, water, and even honey in all samples even though some of the stronger and more animalic samples came up early in the evaluation. For the second evaluation, I used my notes from the previous one to put the samples in order from lightest fragrance to strongest. By doing this I was able to find the more subtle nuances: hints of cedar, definite floral aspects in more of the samples, and green notes appeared as well. But the best find in my second time through was a wonderful deep fruity and wine-like note in two of the samples that I missed the first time around. In one it was intertwined with spicy berries and the other it appeared as a sort of wine-y wood. Honeyed tones also shone through a bit more. I seemed to detect smoke less often and used watery and mossy descriptors less often as well.

Perfumer’s Nose: Oud, The Beginning

AquilariaAstragalusRoyle US Public DomainSo many names – agarwood, oud, oudh, aloeswood, kyara, jinkoh, gaharu, eaglewood, kynam, sinking wood.

So many nuances—incense, wood, smoke, barnyard, balsam, sandalwood, ambergris, animalic, civet, fruity, fresh, minty, herbaceous, vetiver, spicy, peppery, galbanum, honey, castoreum.

Nuanced? Actually, yes, there are quite a few nuanced oud essential oils out there. There are also some with their fair share of stank. To be fair, when I walk out of my studio leaving the many scent strips on my workbench, it is the skank I smell when I come back in. But up close and with my eyes closed there are nuances, themes, accents, touches, and even choruses. But more about that later.

Perhaps I should define the stank part of agarwood; it’s a tough one but here is my take on it. The stronger ones seem to have a strong woody smell with tones of something like armpit or perhaps civet, if civet were a plant. But it’s a really nice armpit, one that maybe not long ago was daubed with honey or some sort of exotic spicy wood essence. You want to smell it again and maybe add a bit of rich fruit or a touch of smoke.

But don’t forget, there are some oud oils with no stank, beautiful worn alone on the skin, and endlessly interesting.

First the tree—there are a number of Aquilaria species comprising agarwood. In its natural state it has a relatively pale heartwood with little or no fragrance. It’s not the wood but the resin, produced as a result of wounding or infection by a fungus, that is aromatic. Age and level of injury act together to produce a highly resinated wood that is aromatic and darkly patterned. The pattern or dark striations on the light wood evoke the pattern of eagle feathers, thus the scientific name Aquilaria meaning eagle. Infection occurs naturally in a portion of the living trees, about 7%. From looking at the tree, it is difficult to determine whether it has produced a resin; cutting into the tree (or cutting it down completely) is often the only way to determine the level of aromatic resin. Over-exploitation has led to a drastic decline in this wood growing naturally in its native habitat throughout Asia with the result that many countries are exploring, with some success, the production of agarwood through cultivation.

Oud or agarwood oil is the product of steam distillation of resinous wood. So many things are involved in the fragrance of the agarwood—infection, wounding, terroir, age of the tree, and even species. In addition, once the wood is harvested it may be treated in a variety of ways before and during distillation. The wood is generally soaked for various lengths of time, water used for soaking may be local water or purified, distillation units may be traditional iron or modern glass, and the length of distillation can extend to days.

world soulThe story of oud is ancient and complex, the ways we use it seem to be the same. In pure form it serves excellently as a personal fragrance, as an incense it has an ancient history continuing to modern times, and more recently it has served as a unique note in perfumes.

Do you have a definition for skank? Do you use or collect agarwood/oud? How do you use it?

Next time I will talk about my search for all the above words and nuances in my samples of agarwood. Many thanks to JK DeLapp of Rising Phoenix Perfume and Katlyn Breene of Mermade Arts for beautiful products, lovely artwork, and free samples.

Perfumer’s Nose: The Green and The Woody of Botanical Musks

In order to discover the actions of several botanical musks, I went to some of my pre-blended heart and base stashes and added a bit of this or that botanical.The base blends were all at 10% strength and the musks were added at 3% of the total. This was probably a bit high for some, definitely for the black currant bud, but made the effect of the musk more apparent for this evaluation. See my previous blog here for a description of each botanical musk. In working with these to evaluate the effects on both floral blends and bases, I eliminated black currant bud because it is very much an accessory note and adds a very individual effect based on a particular blend so difficult to generalize about. I also eliminated costus root because it is very difficult to find and is thought to cause sensitization (basically I don’t want to encourage its use).

The two tables below describe the interactions of four musks with both floral blends and with bases. These are pretty simplistic exercises and I really recommend doing your own experimentation. Botanical musks seem to add more complexity to the mix than some of the animalic musks and the effect is not quite as straightforward. With a strong green or rooty note (spikenard and angelica) or a definite nutty/oily aroma (ambrette seed) these will interact with the floral heart and change a composition. However, having worked out the topnotes and heart notes, ambrette seed and angelica root can add a really lovely sweet musk note to the drydown and spikenard and agarwood contribute their own precious wood notes (not so much musk, at least for the ones I tested) to a perfume.
