How to spot a real oud

The question comes up every week, in two forms. The first: how to be sure that what you are holding is oud. The second, more polite: what justifies the price.

Both lead to the same place. A large portion of what circulates under the name oud is not oud. Estimates commonly cited within niche perfumery suggest a wide majority on mass-market channels, sometimes four bottles out of five. These are synthetic accords, sometimes skilful, sometimes crude, that borrow a few recognisable notes from agarwood and pad them with structural molecules so that an untrained nose finds what it expects.

Three markers

Three markers separate the two worlds with reasonable clarity. The first is price. Agarwood resin forms in defence of the tree against fungal infection, over fifteen to thirty years, and only a small proportion of trees produce it in useful quantity. The material is far less available than sandalwood, in orders of magnitude that make mass production impossible. A three-millilitre bottle at forty euros exists. It is not oud. The question is not whether it is honest or not, it is simply arithmetic.

The second is the evolution on skin. A real oud does not stay still. It opens on a note that is often ungrateful, animalic, sometimes near-fermented depending on the origin, and unfolds over hours toward wood, resin, dry honey or smoke depending on the terroir. At eight hours of wear, it is no longer the same scent as at five minutes. A synthetic accord stays roughly identical from start to finish. That is precisely its commercial purpose. The honest test happens on the wrist, not on paper, and it takes time.

The third is batch-to-batch variation. An artisanal distillation produces a few millilitres at a time, sometimes a few dozen, from specific trees on specific dates. The April batch is not the September one. A brand offering the same olfactory profile sold in thousands of units across three years is doing it with something made in a laboratory, not with what came out of a copper still. Good distillers own these variations. They state them. They know that an informed customer prefers that honesty to a false uniformity.

Secondary tests

Other tests exist, more technical. The colour of the oil, which says little on its own. The viscosity, which can be felt at the drop. The residue on glass when the bottle is rotated, which depends on grade. None of these signals is sufficient in isolation, and skilled counterfeits know how to imitate each. But the three together, price and evolution and variation, cannot be faked at once.

What no test gives

One thing remains that no test provides. Once you have worn a real oud for a full day, the material is recognisable from the second that follows. Synthetic notes stop carrying the same authority. That is the most disorienting effect of the first real bottle: it makes the rest harder to fake past you.
