The Guild defines what artisanal grade oud means and proves it — from accredited peer review, through gas chromatography–mass spectrometry, to species identification of Aquilaria in both oil and wood. A single licensed seal records two distinct findings: what the material is, and how good it is. Both are verifiable by anyone, free, and independent of the seller.
The artisanal oud market has long traded on claims a buyer cannot check — of species, of origin, of grade. The Guild is constituted to replace assertion with method, so that the trust placed in genuine oud can be examined rather than merely extended.
To define what artisanal grade oud means — and to verify that what the consumer is promised is what they receive.
The artisanal oud market runs on reputation and assertion: claims of species, age and origin that a buyer is asked to take on faith. The Guild replaces assertion with method — building, in deliberate stages, from human expertise toward instrumental and accredited rigour, so that every claim attached to genuine oud can be examined rather than merely believed.
A standing panel of master distillers and trained evaluators assesses each submission blind, against a published sensory lexicon that fixes a shared vocabulary for profile, intensity and fault. Panellists are themselves recalibrated against reference material at set intervals to prevent the slow drift of individual palates.
DELIVERS — consensus grade · documented faults · provenance review
Gas chromatography–mass spectrometry resolves the chemical fingerprint of a sample, quantifying the sesquiterpenoids and 2-(2-phenylethyl)chromones that characterise genuine agarwood. The same chromatogram exposes dilution with carrier oils, phthalate plasticisers and synthetic boosting, measured against a catalogue of known adulteration signatures.
DELIVERS — authenticity · grade index · adulteration screen
Developed jointly with university departments in phytochemistry, forestry and conservation genetics, this is a validated framework for establishing Aquilaria species and origin. It combines DNA barcoding — applicable to both distilled oil and raw wood — with chemometric origin models and, at the highest tier, geochemical provenance.
DELIVERS — species · wild / cultivated · geographic origin
Conflating quality with identity is the market's oldest sleight of hand — letting a beautiful aroma stand in for a species claim, or a famous origin imply a grade. The Guild reports each question independently, with its own evidence and its own confidence level, and never permits a strong answer to one to imply an answer to the other. A certificate states plainly what has been established, and what has not.
Is this genuine oud? Is it adulterated, diluted or synthetically boosted? And where does it sit on a defensible scale of grade? This is a chemical and sensory question — first sensed by the panel, then settled at the bench by instrumental analysis read against the reference library.
Which species produced this material — and is it even Aquilaria, rather than one of the other resin bearing genera? Was the source tree wild or cultivated, and from where? Wood anatomy alone cannot resolve Aquilaria to species, so the Guild reads the genome and the geochemistry.
Verification is offered as a graded ladder. A submission may be certified at any rung, and each higher rung subsumes the assurances of those beneath it. The structure is deliberate: the lower rungs require expertise rather than capital equipment, so the Guild can operate and certify from its first month, while the income and reference data from each tier fund the climb toward instrumental and accredited proof.
Each certified submission returns a dated certificate stating the rung achieved and the separate findings for Question A and Question B, with the supporting data retained in the Guild's archive.
Every entry in the library is a known sample — verified species, origin, tree status, age and method of formation — paired with its complete analytical record: GC-MS fingerprint and quantified marker profile, DNA barcode sequences, sensory profile in the standardised lexicon, screening spectra and a full provenance dossier.
Every new submission is graded and identified by correlation against this corpus. This is what allows the Guild to grade by comparison rather than by assertion, to identify species by genetic match rather than by guess, and — decisively — to accumulate the validated reference materials and method data that an international standard requires.
Access is licensed in tiers to researchers and partner laboratories, under provenance and custody rules stricter than those applied to any ordinary submission.
Possession of the library is what makes the Guild the natural author of the standard — not merely a petitioner to it.
Modelled on assay office hallmarking rather than on marketing. The seal is licensed against a specific certified batch, never sold outright, and may be withdrawn — so that its meaning is preserved and a buyer can rely on it.
The rung achieved, the findings for Questions A and B, the certified batch and an expiry date — not a vague endorsement.
A unique identifier resolves, via QR, to a public registry entry showing the certificate's full scope — readable by anyone, at no cost.
Because it can be revoked and is tied to a batch, the mark cannot be diluted by reuse; its scarcity is what makes it worth carrying.
Membership and verification are open to the artisanal community on terms scaled to its breadth — from the single still operator to the established house — so that rigour does not become the privilege of the largest players alone.
Prove the integrity of what you produce. Certify batches at the rung that fits, license the seal, and let independent science speak for the patience and judgement that artisanal distillation demands.
Offer verified provenance and grade at the point of sale. The seal and its public registry convert a claim the buyer must trust into a fact they can check for themselves in seconds.
Scan any seal and read its full scope — species, grade, origin and the rung achieved — instantly, at no cost, and entirely independent of the party selling to you.
The path to a published standard is staged so that each tier of authority funds and earns the next. The Guild standardises only once reproducibility has been demonstrated across laboratories — never before, because a standard asserted ahead of the evidence would devalue the very seal it is meant to protect.
Constitute the body, governance and ethics board. Convene the technical committee and sensory panel, publish the lexicon, and issue the first certificates on expertise alone.
Assemble Reference Library v1 from authenticated donor and member samples. Validate the GC-MS marker panel with a partner laboratory. Launch the seal and the public registry.
Scale GC-MS throughput. Validate DNA barcoding for oil and wood and the origin models. Run interlaboratory ring trials to demonstrate reproducibility — the gate to standardisation.
Formalise the validated methods and engage ISO/TC 54 toward an oud standard, with the sandalwood standard (ISO 3518) as precedent and the library as the basis for reference materials.
Founding membership is open to artisanal distillers and vendors. Join the body that will define artisanal grade oud — and help build the reference library that proves it.
