International Council of Olive’s meeting will be held in Iran
Almost every argument about olive oil quality traces back to one intergovernmental body in Madrid. It has no police force and no market power — and it still decides what the words on your bottle are allowed to mean.
Every so often the olive world’s governing body holds a session in a country that most people do not associate with olives at all — Iran, say, or India, or Argentina. It sounds like diplomatic housekeeping. It is actually how the map of olive growing gets redrawn: an emerging producer hosts, gets technical assistance, sends its agronomists on training courses, and starts aligning its grades with a standard written on the other side of the Mediterranean.
What the International Olive Council is
The International Olive Council is an intergovernmental organisation established under United Nations auspices in 1959 and based in Madrid. Its membership is made up of states and the European Union, and between them those members account for the overwhelming majority of world olive and olive oil production. It is not a company, a lobby group or a certifier. It is a treaty body with four practical jobs: writing the trade standard for olive oils and table olives, validating the analytical and sensory methods used to test them, collecting and publishing production and trade statistics, and running technical cooperation and promotion programmes.
What it does not have is enforcement power. The council writes the standard; national regulators decide whether to adopt it, and national inspectors decide whether to test anything. That gap between a well-written standard and patchy enforcement is where most olive oil quality complaints actually live.
| Extra virgin olive oil | Free acidity not more than 0.8 g per 100 g, peroxide value not more than 20, ultraviolet limits, and a sensory panel finding zero defects with some fruitiness |
|---|---|
| Virgin olive oil | Free acidity not more than 2.0 g per 100 g, with a small tolerance for sensory defect |
| Ordinary virgin olive oil | Free acidity not more than 3.3 g per 100 g; not sold at retail in many markets |
| Lampante virgin olive oil | Above the virgin limits or heavily defective; not fit to consume as it is, sent for refining |
| Refined olive oil | Lampante oil chemically refined; almost no flavour and almost no phenolic content |
| Olive oil | A blend of refined olive oil with some virgin oil for flavour — the plain supermarket grade |
| Olive pomace oil | Extracted from the solid residue with solvents, then refined and blended; a separate product |
| Sensory panel | A trained, standardised tasting panel; the only test that reliably catches a well-deodorised blend |
The grades in plain English
Free acidity is not a taste, it is a measure of how far the oil’s fatty acids have broken free of their glycerol backbone — which happens when fruit is damaged, infested, bruised or left sitting before milling. It is a proxy for how well the fruit was handled. Peroxide value and the ultraviolet absorbance figures measure oxidation, current and past.
None of those numbers can tell you whether the oil tastes good, which is why the standard also requires a trained sensory panel for the top grade. Extra virgin is the only major food grade in the world defined partly by a panel of human tasters, and that peculiarity is deliberate: it is the only method that catches oil which is chemically respectable and organoleptically dead. It is also, unsurprisingly, the part of the standard that gets challenged most often.
Why the United States is outside, and what follows
The United States is not a member of the council, and American olive oil grade standards are voluntary rather than mandatory. That does not mean the United States has no rules — it has federal voluntary grade standards broadly modelled on international ones, plus a state-level standard and a certification seal in California — but there is no equivalent of a mandatory import testing regime backed by a treaty.
This is precisely the gap that produced the great American olive oil argument of the last two decades, in which university testing found a large share of imported supermarket bottles labelled extra virgin failing the international sensory standard, importers disputed the sampling and the methods, and Californian producers argued for tougher enforcement. Whatever you make of the specific figures, the structural point stands: a standard without a mandatory test at the border is a request, not a rule.
Why emerging producers show up
For a country building an olive sector from a low base — Iran, India, Argentina, Australia, Japan, several central Asian states — membership and technical cooperation are worth real money. You get access to validated methods and reference materials, training for agronomists and panel leaders, comparative statistics, and above all a recognised vocabulary. An exporter who can say the oil is extra virgin under the international standard is speaking a language every importer already understands. Without it, you are asking a foreign buyer to trust an adjective.
That is the quiet significance of a council session held in Tehran or anywhere else outside the traditional heartland. It is the standard travelling, one host country at a time — which is how a Mediterranean crop became a global one.
What to take from all this
- Extra virgin is a grade, not a compliment — defined by measurable limits plus a tasting panel.
- Free acidity describes fruit handling, not flavour. Low acidity is necessary, not sufficient.
- Plain olive oil is mostly refined oil with virgin added back for taste. That is legal and clearly defined.
- A claim of meeting the standard means little without a date and a testing body. Ask who tested, and when.
- Pomace oil is a different product, solvent-extracted and refined; it has its uses but should never be confused with virgin oil.
- Where enforcement is voluntary, your own palate is the last line of defence. Learn what a defect tastes like.
The International Olive Council: common questions
What does the International Olive Council do?
It writes the international trade standard for olive oils and table olives, validates the test methods used to apply it, publishes production and trade statistics, and runs technical cooperation and promotion programmes. It has no enforcement powers of its own.
Is extra virgin a legal definition?
Yes, within jurisdictions that adopt the standard. It requires specified limits on free acidity, peroxide value and ultraviolet absorbance, plus a trained sensory panel finding no defects and some fruitiness.
Why is the United States not a member?
The United States has never joined the treaty body. Its grade standards are voluntary and broadly modelled on the international ones, with a stricter state standard and a certification seal operating in California.
What is lampante oil?
Virgin olive oil whose acidity or sensory defects fall below the virgin grades. It is not sold for consumption as it is, but refined and then blended with virgin oil to make plain olive oil.
Does a bottle labelled extra virgin stay extra virgin?
Not necessarily. The grade is assessed at a point in time. Heat, light, air and age can push an oil out of grade long before its best-before date, which is why harvest date and storage matter.
The standard is better than its reputation and worse than its defenders claim, for one reason: it is only ever as strong as the testing behind it. A bottle described as meeting the international standard may have been tested at the mill eighteen months ago, before a summer in a warehouse and a container crossing. Nobody retests it on the shelf. So when a producer tells you their oil meets the standard, the only useful follow-up is: tested by whom, on which lot, on what date. The good ones have the report and will send it to you.
