Organic Olives: What the Certificate Covers on a Jar, Not a Bottle
Organic olives are sold everywhere and explained almost nowhere. Every result on the first page of a search for them is a shop, and the shops make some interesting claims — cured without caustic soda, no colour agents, naturally fermented — without ever saying which of those the organic certificate is actually responsible for. The answer is more interesting than the marketing. A table olive is a processed food and a bottle of oil is not, which means an organic claim on a jar has to cover the cure as well as the grove. This article sets out what the permitted-substance lists say, read from the statute this week rather than repeated from a product page.
For our own oil, see our cold-pressed organic Marrakech olive oil. We do not sell table olives, and nothing here is trying to sell you any.
The Short Answer
- Organic on a jar is a bigger claim than organic on a bottle. Olive oil is mechanically extracted, so its organic certificate is essentially about farming. A table olive is debittered, fermented and packed, so its certificate has to cover the processing too.
- The rules are a positive list, not a ban list. Council Regulation (EC) No 834/2007, Article 19(2)(b), as it stands in Great Britain, permits additives and processing aids in organic food "only in so far as they have been authorised". Anything not on the list is not available.
- The list itself is short. Commission Regulation (EC) No 889/2008, Article 27(1), allows six categories: the substances in Annex VIII, micro-organism and enzyme preparations, natural flavourings, colours for stamping meat and eggshells, drinking water and salt, and certain minerals and vitamins.
- Lye is on the list, but not for olives. Annex VIII permits sodium hydroxide as a processing aid for plant foods "for sugar(s) production; for oil production excluding olive oil production; for the preparation of plant protein extracts". Debittering olives is not among the named uses.
- The blackening agent is not on the list at all. Ferrous gluconate, the stabiliser associated with olives darkened by oxidation, does not appear anywhere in Annex VIII.
- The United States reaches a similar place by a different route. The National List at 7 CFR 205.605 permits sodium hydroxide as a non-agricultural ingredient but adds the words "prohibited for use in lye peeling of fruits and vegetables".
- None of this is a health claim. Organic tells you how something was grown and what was allowed near it during processing. It says nothing about freshness, salt content or quality, and it is not a claim about anybody's health.
Organic on a Jar Is Not Organic on a Bottle
Olive oil is not really processed. The fruit is crushed, churned and spun, and what comes out is separated rather than transformed. That is why an organic olive oil certificate is, in practice, a farming certificate: no synthetic fertilisers, pesticides or herbicides, a conversion period, documented practice, traceability. Our guide to organic olive oil works through that side in full.
A table olive is a different kind of object. It cannot be eaten off the tree, so something has to be done to it — lye, brine, dry salt, or time — and whatever is done becomes part of what "organic" is being asked to vouch for. That is the whole of the difference, and almost nobody selling organic olives explains it.
| Organic olive oil | Organic table olives | |
|---|---|---|
| What the certificate mainly covers | How the olives were farmed | How the olives were farmed and what was allowed into the cure |
| Is it a processed food? | No — mechanically extracted | Yes — debittered, fermented, packed in a medium |
| Governing rules for the processing step | Marketing standards for oil | The organic positive lists, plus Codex CXS 66-1981 for the trade description |
| What is in the pack besides the fruit | Nothing | Brine, sometimes vinegar, sometimes oil, sometimes a firming or colouring agent |
| What the certificate never tells you | Freshness, harvest date, polyphenol content | Freshness, salt level, drained weight, whether it tastes good |
The Rules Are a Positive List
The single most useful thing to understand about organic processing law is its shape. It does not work by listing what is forbidden. It lists what is allowed, and everything else is unavailable by default.
In Great Britain the governing texts are the assimilated Council Regulation (EC) No 834/2007 and its implementing Commission Regulation (EC) No 889/2008. Article 19(2)(b) of the first sets the principle: additives, processing aids, flavourings, water, salt, preparations of micro-organisms and enzymes, minerals, trace elements and vitamins "may be used, and only in so far as they have been authorised for use in organic production". Article 19(3) adds a second constraint that is easy to miss and rather elegant — substances and techniques "that reconstitute properties that are lost in the processing and storage of organic food, that correct the results of negligence in the processing of these products or that otherwise may be misleading as to the true nature of these products shall not be used".
Article 27(1) of the implementing regulation then says exactly what "authorised" means. Six categories, and no others.
| Category permitted by Article 27(1) | What it covers | Relevance to a jar of olives |
|---|---|---|
| (a) Substances listed in Annex VIII | The additive and processing-aid lists | The operative one — see below |
| (b) Preparations of micro-organisms and enzymes | Cultures normally used in food processing | Directly relevant to a fermented olive |
| (c) Natural flavourings | As defined in the flavourings regulation | Herbs and aromatics in the packing medium |
| (d) Colours for stamping meat and eggshells | Exactly what it says | None |
| (e) Drinking water and salt | Sodium chloride or potassium chloride as basic components | The brine itself |
| (f) Minerals, vitamins, amino acids, micronutrients | Only where legally required or specifically authorised | None |
Read that list again with an olive in mind and the picture forms on its own. Water, salt, a live culture, a few herbs, and whatever Annex VIII allows. That is the toolkit.
What That Means for the Cure
Annex VIII was substituted in full by Commission Implementing Regulation (EU) 2019/2164 and has been amended twice since for Great Britain, most recently with effect from 1 January 2026. It runs in three sections: food additives, processing aids, and processing aids for yeast. Two entries in it decide most of what an organic olive can be.
Sodium hydroxide appears twice, and neither entry is about olives. As a food additive, E 524 is permitted in plant foods only for "surface treatment of Laugengebäck" — the German lye pastry — and for regulating acidity in organic flavourings. As a processing aid it is permitted for plant foods "for sugar(s) production; for oil production excluding olive oil production; for the preparation of plant protein extracts". Debittering table olives is not among the named uses, and the olive oil carve-out is explicit in the other direction: caustic refining of olive oil is specifically excluded.
Ferrous gluconate does not appear in Annex VIII at all. That is the substance associated with fixing the uniform colour of olives darkened by oxidation — the sliced black olives in cans, which Codex treats as a separate trade preparation from naturally fermented fruit, as our piece on Kalamata olives sets out. Its absence from a positive list is not a small detail, and Article 19(3)'s bar on substances that "may be misleading as to the true nature" of an organic food points the same way.
What is on the list reads like a description of a traditional brine cure: lactic acid (E 270), citric acid (E 330), ascorbic acid (E 300), carbon dioxide, sodium carbonates, water and salt. A naturally fermented olive needs almost nothing that is not already there.
The Same Question in the United States
American organic rules are built differently — a National List of permitted non-agricultural substances rather than an annex of additives and processing aids — but they land close to the same place on the one question that matters here.
At 7 CFR 205.605(b), the entry reads in full: "Sodium hydroxide—prohibited for use in lye peeling of fruits and vegetables." The substance is permitted; one named use of it is not. And on the colour question, the National List carries ferrous sulfate, for iron enrichment or fortification where required or recommended, and no ferrous gluconate.
| Question | Great Britain — Reg. (EC) 889/2008, Annex VIII | United States — 7 CFR 205.605 |
|---|---|---|
| Is sodium hydroxide permitted at all? | Yes, as an additive and as a processing aid | Yes, as a non-agricultural ingredient |
| Which uses are named? | Additive: Laugengebäck and acidity in flavourings. Aid: sugar, non-olive oil production, plant protein extracts | Not itemised, but lye peeling of fruits and vegetables is expressly prohibited |
| Is olive debittering named? | No | No |
| Is ferrous gluconate listed? | No | No — ferrous sulfate only, for iron fortification |
| Structure of the rule | Positive list; unlisted means unauthorised | Positive list with per-substance annotations |
Two honest limits on all of that. We read the Great Britain texts, which are the assimilated versions of 834/2007 and 889/2008; the European Union has since replaced 834/2007 with its own newer regulation for its own market, and we have not read that text this week, so we are not going to characterise it. And a substance being absent from a positive list is not the same thing as a named prohibition of every conceivable process. Certifiers interpret, derogations exist, and equivalence arrangements apply to imports. What we can say is what the lists say.
What Organic Does Not Tell You
Everything above is about inputs. A great deal that decides whether a jar of olives is any good is untouched by it.
An organic certificate says nothing about salt. Table olives are preserved in brine, and that is a matter of food safety rather than recipe: Codex CXS 66-1981 sets a floor of 6.0% sodium chloride and a ceiling of pH 4.3 for natural olives in brine. An organic olive is not a low-salt olive, and no certificate makes it one.
It says nothing about how much of the jar is fruit. Codex sets a minimum drained weight of 50% for whole olives and 40% for stoned or stuffed ones, against the container's water capacity. Organic or not, a jar is allowed to be substantially brine.
It says nothing about variety, freshness or how long the pack has sat. If origin and cultivar are what you are after, a protected designation is the instrument that carries them, and our guide to Greek olives works through eleven of them.
And it is not a claim about health. That deserves saying plainly, because it is the thing organic marketing most often implies without stating. Organic describes farming method and permitted inputs. It is not a nutritional claim, it is not a medical one, and no cured olive is a treatment for anything.
The Objections Worth Taking Seriously
"You sell organically grown oil, so this is a sales argument." It would be, except that we sell no table olives at all and we hold no organic certificate for anything. If this page were written to flatter our own position it would argue that certificates do not matter. It argues the opposite: the certificate is a real instrument with a readable specification behind it, and that is precisely why it is worth knowing what it does and does not reach.
"You are reading absence from a list as prohibition." A fair challenge, and we have tried to be careful about it above. The honest form of the point is narrower: organic processing rules in both jurisdictions are positive lists, olive debittering is not a named permitted use of lye in either, and the blackening agent is on neither list. Whether a particular certifier permits a particular process by another route is a question for that certifier's standard, which we have not read.
"Organic olives cost more, so they must be better." They are grown under a specific, audited regime, and for many people that is reason enough. What the certificate does not do is tell you the fruit was well grown, well cured, well graded or recently packed. Those come from the producer, not the scheme.
Why Sidr & Stone
This is a topic where the honest position is a slightly awkward one for us, so here it is first: our own oil is organically grown and we do not hold a formal organic certificate. We describe the farming and let you judge it rather than print a mark we have not earned. If a certified organic label is your single non-negotiable, a certified product is the right choice and we will not pretend otherwise.
- Single-estate — one family-owned grove on the plains outside Marrakech, Morocco, with no blending across origins.
- Rain-fed — no irrigation; the trees take what the season gives them.
- Organically grown — no synthetic fertilisers, pesticides or herbicides, and no certificate claimed.
- Single harvest — a small batch, once a season, picked when the fruit is ready rather than when the calendar says so.
- Cold-pressed within hours of harvest — flavour, aroma and polyphenols preserved by keeping the gap between picking and pressing short.
- Unfiltered extra virgin — minimally processed, and it may show natural sediment, which is normal for an unfiltered oil.
- 100% natural — one ingredient, with nothing added to it.
- 500 ml dark glass with a gold label — protective packaging in a size built to be finished fresh.
- Halal certified, with 10% of profits to charity as a brand-wide commitment.
- Fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is the best olive oil — that would be exactly the sort of unbacked adjective this article is about. We publish no polyphenol figure for our oil yet, and we would rather say so plainly than imply one. For the wider set of things a bottle can genuinely tell you, see our guide to choosing a quality olive oil.
Frequently Asked Questions
What are organic olives?
Table olives grown under a certified organic regime and cured using only substances authorised for organic processing. Because a table olive is a processed food, the certificate has to cover the cure as well as the grove — which is the main way an organic olive differs from organic olive oil.
Can organic olives be cured with lye?
Not by any use named in the lists we read. In Great Britain, Annex VIII to Regulation (EC) No 889/2008 permits sodium hydroxide as a processing aid for sugar production, non-olive oil production and plant protein extracts only. The United States National List permits it but expressly prohibits lye peeling of fruits and vegetables.
Are organic olives healthier than ordinary olives?
Organic is not a health claim and we are not going to turn it into one. It describes farming method and the inputs permitted during processing. Cured olives of every kind are salty by construction, and none of them is a treatment for anything.
What does organic certification actually cover on a jar of olives?
Growing without synthetic fertilisers, pesticides or herbicides, plus the processing rules: only water, salt, permitted cultures, natural flavourings and the substances in Annex VIII may go into the pack. It does not cover salt level, drained weight, freshness or flavour.
Are black canned olives ever organic?
The route matters more than the answer. Olives darkened by oxidation are a distinct Codex trade preparation, and ferrous gluconate, the agent associated with fixing that colour, appears on neither the Great Britain nor the United States permitted list. Read the trade preparation on the label, not the colour.
Is organic olive oil the same claim as organic olives?
No, and this is the practical point. Oil is mechanically extracted, so its certificate is essentially about the grove. Olives are debittered, fermented and packed, so the certificate has to reach into the processing as well.
Does Sidr & Stone sell organic olives?
No. We sell a single-estate Moroccan extra virgin olive oil and no table olives. Our own olives are organically grown without synthetic inputs, and we hold no organic certificate, which we say plainly rather than imply otherwise.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
The useful thing about organic olives is not that the certificate is a guarantee of quality. It is that the certificate is readable. Behind the green leaf on the jar there is a regulation, and behind the regulation an annex, and the annex is a list of about sixty substances you can go and look at. Very little else on a food label works that way.
What the list turns out to describe, once you read it with an olive in mind, is close to the oldest method there is: fruit, water, salt, a live ferment and time. Whether that makes a better olive than a lye-cured one is a matter of taste. What it does mean is that the word on the front of an organic jar is pointing at a real and specific set of constraints, which is more than most words on most jars manage.
That is the same discipline we try to apply to our own aisle, where knowing what the two halves of the olive harvest actually involve does more for a buyer than any adjective. Our cold-pressed organic Marrakech olive oil — single-estate, rain-fed, organically grown and unfiltered — is available to pre-order, with fulfilment in the UK, EU, and US. First harvest, estimated shipping from November 2026.
