In short
A woody accord is built by layering materials with different textures: dry and pencil-like, creamy, smoky, earthy and transparent. The common mistake is treating "wood" as one smell and stacking until it goes muddy. This workshop has you map your woods first, then build with a defined role for each.
What you will learn
- Map woody materials by texture rather than by name
- Layer woods without muddying them
- Evaluate a slow, low-impact accord fairly
Before this lesson: Rose Accord Workshop
Map by texture, not by name
| Texture | Examples | Typical role |
|---|---|---|
| Dry, pencil | Virginia cedarwood | Structure |
| Sweet, resinous dry | Atlas cedarwood | Warmth |
| Earthy, smoky, rooty | Vetiver | Depth, contrast |
| Dark, sweet-earthy | Patchouli | Depth, sometimes dominance |
| Smoky, tea, faintly rosy | Guaiac wood | Soft smoke |
| Creamy, milky | Sandalore, Javanol, sandalwood | Softness, body |
| Transparent, velvety | Iso E Super | Diffusion, volume |
| Dry amber-wood | Cedramber | Dry lift and radiance |
The guides on woody notes, cedarwood and vetiver cover grades and sources. For this workshop, work with two to four materials you actually own. Real sandalwood is costly and supply-constrained, as the sandalwood guide explains, so most learners use synthetic sandalwood materials instead.
A layering plan
- W1, structure: your dry wood alone at 10%, on a strip, as the reference.
- W2, add softness: one creamy material, in a ladder of 3:1, 1:1 and 1:3 with W1.
- W3, add depth: vetiver or patchouli at a low ratio such as 10:1. These can take over quickly.
- W4, add diffusion: Iso E Super or similar. Compare with and without, blind if you can.
Judging slow accords
Most of these materials are low in volatility and many are low in impact, which creates two problems. First, you need time: check at 1 hour, 6 hours, 24 hours and 48 hours. Second, you can stop perceiving them. You may have noticed in How Smell Works that some materials register weakly for some people. So do not increase a low-impact material merely because you cannot smell it. Compare with and without, and ask someone else.
These accords are slow to judge but quick to contaminate. Woody materials cling to hands, surfaces and strips, and they outlast everything else in the room. Keep old strips well away.
Cost and supply
Woods include some of the most supply-sensitive materials in perfumery. Certain sandalwoods and rosewoods have been subject to conservation concerns, and the CITES guide sets out how international listings can affect them. Note the species and source of what you buy.
Practical exercise: Build a woody accord in layers
- Map your own woods at 10%, adding a texture word for each from your own perception.
- Write your goal: for instance, a dry cedar with smoke, or a soft milky wood.
- Build W2, W3 and W4, keeping earlier versions, and working in the order above.
- Judge at 1, 6, 24 and 48 hours. Rewrite your goal if the accord has shown you something better.
- Ask someone else to compare your final version with W1, and note their words.
You have done this well if each material has a stated job, your judgment is based on times beyond the first hour, and you tested any low-impact material by comparison rather than by smelling it alone.
Common mistakes
- Adding more because you cannot smell it. You may be anosmic or adapted. Check first.
- Using five woods at equal doses. You get a brown blur. Give one material the lead.
- Letting patchouli or vetiver run away. Both can dominate at low doses. Start low.
