How to check the kava you are buying is noble

"Noble" appears on kava packaging so often that it has started to lose its meaning, but the word has a specific legal history and a narrower definition than most labels suggest. Before you buy, it helps to know where the term comes from, what a lab report actually tests for, and which questions a good vendor should be able to answer without hesitation.

What "noble" means in law

The word comes from Vanuatu's own regulation of its kava industry. The Kava Act No. 7 of 2002 sorts kava varieties into four schedules: noble varieties in Table 1, medicinal varieties in Table 2, two-day (tudei) varieties in Table 3, and wichmannii varieties in Table 4 (Vanuatu Kava Act No. 7 of 2002, verified against the official text and the FAOLEX legal database mirror). Only noble varieties, plus their recognised synonyms from island to island, may legally be exported from Vanuatu. That distinction, a named variety sitting on a government schedule, is the actual legal basis for the word "noble". It is not a flavour category, a marketing tier, or a synonym for good quality. It is a list.

Because the Act is Vanuatu's domestic export law, it never governed what a shop in Warsaw or Los Angeles is allowed to call kava once the root has left the country. No EU member state has a novel food authorisation for kava at all, so European buyers are dealing with an unauthorised food category regardless of cultivar (European Commission, Novel Food status catalogue). Kava is banned outright as a food in Poland, the United Kingdom and the Netherlands, and in Germany it sits closer to prescription medicine territory than the open market (Herbal Reality, An update on kava regulations: 2025 global overview). If you are ordering into any of those four countries, the legal question comes before the noble question. See kava.fyi's guides for Poland, the United Kingdom, the Netherlands and Germany before you order.

Why two-day (tudei) matters

Tudei is Bislama for "two-day", a plain description of how long its effects and after-effects can run. Table 3 of the Vanuatu Kava Act exists specifically to keep these varieties out of export shipments, because their kavalactone chemistry, heavier in dihydromethysticin relative to a noble profile, is the chemistry most consistently associated with the nausea, grogginess and liver-safety questions that damaged kava's reputation in Europe in the early 2000s (Teschke, Kava, the anxiolytic herb: back to basics to prevent liver injury?, British Journal of Clinical Pharmacology, 2011). A shop that cannot tell you which named cultivar is in the bag, or whether that cultivar sits in Table 1 or Table 3, is asking you to trust a word it may never have checked itself.

What a certificate of analysis actually shows, and what it does not

A certificate of analysis (COA) is a lab report on one specific batch. At minimum it should state total kavalactone content as a percentage of dry weight, and most reputable labs also screen for heavy metals and microbial contamination. A fuller COA breaks that total down into the six-number chemotype described below. What a COA does not automatically do is confirm the cultivar name, confirm that the material is root rather than aerial parts, or confirm noble status under the Vanuatu schedule. A lab reports on what it is asked to test, and "kavalactone percentage" is a different measurement from "noble". Read the cultivar atlas and the kavalactones page alongside any COA a vendor sends you, so the numbers on the certificate mean something specific rather than sounding reassuring in the abstract.

What a chemotype code tells you, and what it cannot

The six-digit chemotype code ranks the six major kavalactones, desmethoxyyangonin, dihydrokavain, yangonin, kavain, dihydromethysticin and methysticin, from most to least abundant in that sample, a numbering system introduced by Lebot and Levesque (International Kava Organization, Decoding the Experience: 6 Essential Numbers). A code that opens with 4 or 6 generally correlates with the heady-to-balanced noble varieties Pacific communities have used for centuries; a code that opens with 2, alongside a high share of dihydromethysticin, correlates with tudei chemistry. This makes the chemotype a useful proxy, but only a proxy. It describes ratios in one lab sample, not the legal identity of the plant, and it says nothing about whether the batch tested is root or aerial material, or whether the figures were run on the batch you are actually buying rather than a reference sample from the same supplier.

Which vendors publish certificates, and which do not

kava.fyi tracks the disclosure practices of every vendor in its price comparison, based on what each vendor publishes on its own site. Kalm with Kava, Bula Kava House, Root of Happiness, Kava Depot, Captain Cook's Kava and The Kava Society New Zealand all publish certificates of analysis, though the detail varies: Root of Happiness states chemotype and percentage per product, Bula Kava House gives a kavalactone profile per varietal, Kava Depot lists extracts by percentage, and Captain Cook's Kava publishes batch-specific figures. Nakamal at Home publishes kavalactone percentages but only partial documentation. Wakacon says it tests but has not published certificates, kava.com (Kona Kava Farm) and TRU KAVA publish weak or incomplete documentation, and Leilo makes certificates available only on request. Gourmet Hawaiian Kava, Kavafied, Kava Europe, Kava Club, Kava Mode and Melo publish no certificate of analysis at all, according to kava.fyi's tracking. Kavaha, the Poland-based vendor run by the same people who operate this site, also falls into the "none published" group as of the last check. kava.fyi discloses this because Kavaha is held to the same disclosure standard as every other vendor in its tables, and no vendor pays to be listed (products.json, pulled 16 September 2026).

Red flags on a label

No cultivar named, only a generic "kava root powder" with no named variety.
"Aerial parts" or "whole plant" anywhere in the ingredient list. Noble kava is a root and rootstock product, and aerial material is the part most consistently linked to liver-safety concerns (Teschke, 2011).
"Kava extract" with no stated extraction method, whether water, ethanol or acetone, and no stated percentage.
No stated origin island or country, since chemotype and noble status are tied to specific growing regions.
A chemotype code offered with no lab name and no batch date attached, since an unverifiable number is not meaningfully different from no number at all.

Questions to send a vendor before you order

Which named cultivar is this, and which Vanuatu Kava Act schedule, or equivalent classification from its country of origin, does it sit in?
Can you send the certificate of analysis for the specific batch you would ship me, not a generic reference certificate?
Is this root material only, or does it include stems or leaves?
What extraction or preparation method was used, if this is anything other than raw grind?
Which lab ran the test, and when?

A vendor with nothing to hide usually answers all five without friction. One that answers only the first two, or goes quiet, has told you something too. For general reference while you compare answers, kava.fyi's cultivar atlas, kavalactones page and price comparison are free to check against whatever a vendor tells you.
