Sitia Olive Oil: The Cretan PDO and What Its Rules Actually Say
If you have picked up a tin of Sitia olive oil in eastern Crete, or seen the name on a bottle at home, it is worth knowing precisely what that word is doing on the label. Sitia is a real place — a town and a province at the far eastern end of Crete, in the Prefecture of Lasithi — and it is also a protected name in European law. But the name is protected twice over, for two entirely different products, and the one most people mean when they say Sitia olive oil is not the one registered as plain Sitia. We went to the European Commission's own register to check, and the answer turned out to be more precise, and rather more interesting, than the marketing copy around it.
For our own oil, see our cold-pressed organic Marrakech olive oil.
The Short Answer
- The olive oil name is registered as Σητεία Λασιθίου Κρήτης / Sitia Lasithiou Kritis, a Protected Designation of Origin with the file number PDO-GR-0052, protected on 21 January 1998 and recorded in the oils-and-fats category of the EU register.
- Plain Σητεία / Sitia is also a PDO — but a wine one. It sits in the register as PDO-GR-A1613, protected on 11 June 1981, alongside Malvasia Σητείας (PDO-GR-A1608, 2011). Same word, different product, different file.
- The registration dossier describes an extra virgin oil from the Koroneiki variety, grown and pressed inside a delimited zone of named villages plus the town of Sitia, in the province of Sitia in the Prefecture of Lasithi.
- The specification sets its own chemistry, and it is tighter than the general extra virgin rule. A January 2022 register filing quotes the specification as requiring K232 ≤ 2.30 and K268 ≤ 0.15 at bottling, against the 2.50 and 0.22 that the trade standards allow.
- The register also records the one season those limits were relaxed. For 2021/22 only, they were raised to the legal maxima after drought — the filing cites a May that was the warmest in 35 years and total rainfall of just 13.1 mm from May to September in representative parts of the zone.
- Sidr & Stone is not a PDO oil and does not pretend to be. Ours is a single-estate, rain-fed, organically grown Moroccan oil, cold-pressed within hours of harvest — and we publish no polyphenol figure, which we would rather state plainly than imply.
What "Sitia" Names in the EU Register — and What It Does Not
The European Commission keeps a public register of protected geographical names called eAmbrosia. It is the only place where the question "is this name actually protected, and for what?" has a definitive answer. On 26 August 2026 we pulled all 4,011 entries and filtered them ourselves rather than working from a producer's description.
Sidr & Stone's reading of that register shows the olive oil is protected as Σητεία Λασιθίου Κρήτης / Sitia Lasithiou Kritis under file number PDO-GR-0052, with an EU protection date of 21 January 1998. The bare name Σητεία, on its own, belongs to a different file entirely — a wine PDO dating from 1981.
This is not a pedantic distinction. It is the same trap that catches readers of Greek and Italian regional names generally: a place that makes both wine and oil often has two separate registrations, and the shorter, more marketable form of the name usually belongs to the wine. We hit the identical pattern when we looked at Laconia, and again at Messinia, where the Greek word most people search turns out to name something quite different from what the label implies.
| Registered name | File number | Type | Product | EU protection date |
|---|---|---|---|---|
| Σητεία Λασιθίου Κρήτης / Sitia Lasithiou Kritis | PDO-GR-0052 | PDO | Olive oil (oils and fats) | 21 January 1998 |
| Σητεία | PDO-GR-A1613 | PDO | Wine | 11 June 1981 |
| Malvasia Σητείας | PDO-GR-A1608 | PDO | Wine | 30 December 2011 |
The register lists the instrument that created the olive oil designation as Commission Regulation (EC) No 134/98, published in Official Journal L 15 of 21 January 1998. It also records later activity on the file: an amendment application published in Official Journal C 226 of 14 June 2021, its approval in Official Journal L 355 of 7 October 2021, and a further standard amendment communicated in the Official Journal of 14 January 2026. We could not read those texts — EUR-Lex was serving a degraded page throughout our checks — so nothing in this article is quoted from them. Where we give a figure, it comes from a document we actually opened.
The Zone: The Province of Sitia, in Lasithi
The original registration summary, which the register still serves as an attachment, is a plain administrative document rather than a piece of marketing, and it is all the better for it. It names the applicant group as the Union of Agricultural Cooperatives of Sitia, at Mysonos 74, 72300 Sitia, Crete. It files the product under class 1.5, oils and fats. And it describes the oil in one sentence: an extra virgin olive oil of exceptional quality produced from the Koroneiki variety, in which the olive fruit fly is controlled by ground-level spraying or by biological methods.
The geographical area is then given as a list — the administrative boundaries of named villages including Zakros, Piskokefalos, Praisos, Skopi, Myrsini, Tourloti, Sfaka, Chandras and Ziros, together with the town of Sitia itself, all within the province of Sitia in the Prefecture of Lasithi. Crucially, the dossier requires that the product be made exclusively from olives grown in that area and processed there. Growing and milling both have to happen inside the zone; you cannot lorry the fruit somewhere cheaper.
Two further details in that document are worth knowing, because they are the parts that give the name teeth. The inspection body is the Agriculture Directorate of the Prefecture of Lasithi — a named authority, not a self-declaration. And the labelling section specifies a control number carried on the pack, tied to a serial number and the last two digits of the year of production. A name with an inspection body and a serial number behind it is a different kind of claim from a name printed because it sounds good.
For context, Crete alone holds nine registered olive oil names in the EU register — Chania Kritis, Peza Irakliou Kritis, Vorios Mylopotamos Rethymnis Kritis, Viannos Irakliou Kritis, Apokoronas Chanion Kritis, Sitia Lasithiou Kritis, Kolymvari Chanion Kritis, Arxanes Irakliou Kritis and Selino Kritis — and Greece as a whole has 33 in the oils-and-fats category. Sitia is one entry in a dense map, not a lone landmark. The cultivar behind most of them is the same small, hardy olive we cover in full in our guide to Koroneiki olive oil, and the best-known Greek registration of all is the one we examine in our piece on Kalamata olive oil.
Where the Sitia PDO Is Stricter Than the Extra Virgin Rule
This is the part almost nobody writes about, and it is the most useful thing on the file.
Extra virgin olive oil has to clear a set of laboratory limits before it can be called extra virgin at all. Two of them are ultraviolet absorbance coefficients: K232, which rises with the conjugated dienes formed early in oxidation, and K270, which rises with conjugated trienes and with the traces left by refining. Under the International Olive Council trade standard COI/T.15/NC No. 3/Rev. 22 of June 2026 and the live EU rules — Regulations (EU) 2022/2104 and 2022/2105, the instruments that replaced the long-repealed Regulation (EEC) No 2568/91 — extra virgin oil must sit at K232 ≤ 2.50 and K270 ≤ 0.22, alongside free acidity of no more than 0.80% expressed as oleic acid, a peroxide value of no more than 20.0 milliequivalents of active oxygen per kilogram, a defect median of 0.0 and a fruity median above 0.0.
The Sitia specification asks for more. A filing lodged on the register in January 2022 quotes the product specification's own chemical characteristics chapter, and it sets the bar at K232 ≤ 2.30 and K268 ≤ 0.15 at bottling. Both numbers are inside the general legal ceiling with room to spare. A PDO does not have to do that — many designations simply restate the legal minimum and stop — so a scheme that writes tighter numbers into its own rules is telling you something real about how it expects its oil to be made and stored.
One honest caveat before the table. The Sitia specification states K268 where the trade standards state K270. These are absorbance readings taken at slightly different wavelengths and they are not the same measurement, even though they are used for the same purpose and the register document treats 0.22 as the ceiling drawn from extra virgin legislation. We report both as written rather than silently converting one into the other.
| Measure | Extra virgin limit (IOC Rev. 22 / EU 2022/2104) | Sitia PDO specification, at bottling | Sitia PDO, 2021/22 season only |
|---|---|---|---|
| K232 | ≤ 2.50 (optional between commercial partners under Rev. 22) | ≤ 2.30 | ≤ 2.50 |
| K270 / K268 | K270 ≤ 0.22 | K268 ≤ 0.15 | K268 ≤ 0.22 |
| Free acidity (% oleic) | ≤ 0.80 | Not quoted in the filing we could read | Unchanged |
| Peroxide value | ≤ 20.0 meq O₂/kg | Not quoted in the filing we could read | Unchanged |
| Sensory panel | Defect median 0.0, fruity median > 0.0 | Not quoted in the filing we could read | Unchanged |
The Season the Limits Moved — and What Drought Does to a Rain-Fed Oil
The reason we can quote the Sitia specification's numbers at all is that in January 2022 the Greek authorities filed a temporary amendment to relax them, and the register published the file. It is a short document, in Greek, and it is unusually candid.
The request was to raise K232 from 2.30 to 2.50 and K268 from 0.15 to 0.22 — that is, up to the general extra virgin maxima — for the 2021/22 olive season and no other. The justification is weather. The filing describes drought and prolonged high temperatures across the delimited zone, states that that May was the warmest in 35 years, and records total rainfall of just 13.1 millimetres between May and September in representative parts of the zone. The applicants were the Sitia union of agricultural cooperatives together with the Municipality of Sitia and the local farmers' association, who had also applied to the Greek agricultural insurance organisation for compensation over reduced fruit set.
What makes the document genuinely interesting is its reasoning. It notes that the published literature reports K232 and K268 values being higher in trees that are not irrigated, and falling as irrigation water increases — and it attributes that to the higher concentration of phenolic compounds in water-stressed fruit, which absorb in that region of the ultraviolet spectrum. It cites work on the Koroneiki variety specifically, in which the year with less rainfall and higher temperatures produced oil with a greater phenolic content and higher K232 and K268 readings.
That is a nuance worth sitting with, because it cuts against the intuition that a lower K number is simply a better oil. In a rain-fed grove in a dry year, part of what pushes those readings up is the very chemistry that people prize. The file also makes the practical point that these values rise naturally during storage, so an oil starting the season higher was expected to have a shorter usable life — which is why the producers wanted headroom that would last until the bottle reached the shopper, not just until it left the mill.
We read all of this with some interest, because our own grove is rain-fed. The trees outside Marrakech take what the season gives them and nothing else, and the harvest waits until the fruit is genuinely ready rather than when the calendar says so. We are not going to turn that into a claim about our chemistry — we have not published a polyphenol figure and are not about to imply one from someone else's dossier. But the mechanism the Sitia file describes is the same mechanism our farming sits inside, and it is a more honest way to think about water and olive oil than "more rain is better".
Three Objections Worth Answering
"A PDO tells you where an oil is from, not how good it is." Largely fair, and it is the most common sensible criticism of the whole scheme. A designation guarantees origin, method and a set of minimum characteristics; it does not guarantee that the bottle in front of you is excellent, or fresh, or well stored between the mill and the shelf. What Sitia's file adds is a written ceiling tighter than the law and a named inspection authority, which is more than most origin claims carry. It still is not a substitute for buying a recent harvest from a seller who turns stock over.
"Tighter numbers on paper do not survive a year in a warehouse." True, and the register itself says so. The 2022 filing's own argument rests on the fact that K values climb during storage, which is precisely why the producers asked for headroom rather than a one-off dispensation at the mill. The number that matters to you is the one in the bottle when you open it, and no specification can control how long that bottle sat in a hot shop window. Buy the newest crop you can find, keep it dark and cool, and use it.
"You sell Moroccan oil — of course you would relativise a Greek PDO." A reasonable suspicion, so here is the plain version. The Sitia designation is a real, well-documented scheme with an inspection body, a delimited zone, a named cultivar and chemistry limits stricter than the legal floor. We hold nothing equivalent. Sidr & Stone has no PDO, no PGI and no organic certificate; our olives are organically grown rather than certified organic, and we say so on every page rather than blur the two. What we offer instead is a single named estate, one harvest, and no blending across origins. Those are different kinds of assurance, and a reader is entitled to prefer the Greek one.
How to Read a Sitia Label Without Buying the Wine
A short, practical checklist, in the order it is worth applying.
- Look for the full registered name, not the short one. An olive oil trading on this designation should carry Sitia Lasithiou Kritis or its Greek original, with the EU PDO mark. Sitia on its own is a wine name and, on a bottle of oil, tells you only that someone liked the word.
- Confirm the grade separately. The designation covers an extra virgin oil, but grade and origin are two different statements and both should appear.
- Find the harvest or crop year. Nothing in the register text we could read requires one, and it is the single most useful number on any olive oil label.
- Check for the control number. The registration file specifies a serialised control number with the last two digits of the production year. Its absence is not proof of anything, but its presence is a good sign.
- Ignore the colour. Green, gold or somewhere between tells you almost nothing about quality; it is the least informative thing on the bottle.
For the brand-agnostic version of all of this — grade words, harvest dates, packaging, and the marketing phrases that mean nothing — our guide to choosing a quality olive oil walks through the whole label. If a Sitia oil looks cloudy rather than bright, that is a separate question with a separate answer, and we cover it in our piece on unfiltered versus filtered olive oil.
One polyphenol figure does carry legal weight in the EU, and it is worth stating precisely because it is so often garbled. Regulation (EU) No 432/2012 permits an olive oil polyphenol claim only where the oil contains at least 5 mg of hydroxytyrosol and its derivatives per 20 g of oil, and it requires the label to inform the consumer that the beneficial effect is obtained with a daily intake of 20 g. That is a specific measured fraction, not a total-polyphenol number, and the two are not interchangeable. The Sitia specification we read does not set one. Neither do we.
| What a buyer can check | Sitia PDO (the scheme) | Sidr & Stone |
|---|---|---|
| Origin name protected in EU law | Yes — PDO-GR-0052 | No — we hold no PDO or PGI |
| Delimited growing and pressing zone | Yes — named villages and the town of Sitia | One family-owned grove near Marrakech; no scheme behind it |
| Cultivar named in the file | Yes — Koroneiki | Not published as a named cultivar |
| Independent inspection body | Yes — named in the registration file | No third-party scheme; organically grown, not certified organic |
| Maximum K232 / K268 fixed in writing | Yes — 2.30 / 0.15 at bottling | Not published |
| Total polyphenols (mg/kg) | Not set by the specification we read | Not published |
| Batch size | Not limited by the scheme | One small single harvest per season |
| Grade and processing | Extra virgin | Unfiltered extra virgin, cold-pressed within hours of harvest |
Why Sidr & Stone
We are the wrong shape of producer to compete with a designation, and we are not going to pretend otherwise. What we do instead is name one place and stay there.
- 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 formal organic certificate, which we state rather than blur.
- Single harvest — a small, limited batch pressed once a season, picked only when the fruit is genuinely ready, sometimes weeks later than neighbouring farms.
- Cold-pressed within hours of harvest — flavour, aroma and polyphenols protected by pressing quickly and without added heat.
- Unfiltered extra virgin — minimally processed, so it may carry a little natural sediment.
- 100% natural — one ingredient, olive oil, and nothing else.
- 500ml dark glass with a gold label — protective packaging against light.
- Halal certified, with 10% of profits going to charity, and 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 claim this article has spent its length picking apart. What we will say is that our oil is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, that we publish no polyphenol figure and say so openly, and that the evidence of the care is in the taste, the colour and the size of the season's pressing.
Frequently Asked Questions
What is Sitia olive oil?
Sitia olive oil is extra virgin olive oil from the province of Sitia at the eastern end of Crete, in the Prefecture of Lasithi. Its protected name in the EU register is Σητεία Λασιθίου Κρήτης / Sitia Lasithiou Kritis, file number PDO-GR-0052.
Is Sitia olive oil a PDO?
Yes. It has held Protected Designation of Origin status since 21 January 1998, under the registering instrument the register lists as Commission Regulation (EC) No 134/98, published in Official Journal L 15 of that date.
Why is "Sitia" also a wine name?
Because the same place registered both. Σητεία is a wine PDO in its own right (PDO-GR-A1613, protected 11 June 1981), as is Malvasia Σητείας (PDO-GR-A1608). The olive oil sits under the longer name, which is why the full form matters on a label.
What olive variety is Sitia olive oil made from?
The registration dossier names the Koroneiki variety — the small, hardy olive behind most Greek extra virgin oil. It is prized for stability and a green, peppery character rather than for yield per fruit.
Is Sitia olive oil better than other Cretan olive oils?
Not automatically. Crete holds nine registered olive oil names and Sitia is one of them. What the Sitia file does carry is a specification with K232 and K268 ceilings tighter than the general extra virgin limits, which is a real point of difference on paper.
How does Sidr & Stone compare with a Sitia PDO oil?
They answer different questions. A Sitia PDO oil offers a legally protected origin, a delimited zone and an inspection body. Sidr & Stone offers a single named Moroccan estate, one small rain-fed harvest a season, and no blending — with no designation and no organic certificate.
Where can I buy Sitia olive oil?
Mostly from Greek producers, specialist importers and delis, and in Crete itself. Look for the full registered name and the EU PDO mark rather than the word Sitia on its own. Sidr & Stone is sold direct rather than through retailers.
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
Sitia olive oil is a genuinely well-documented designation, and the documentation rewards the reading. Behind a word that most shoppers treat as decorative sits a delimited zone, a named cultivar, a named inspection authority, a serialised control number, and a set of laboratory limits that the scheme has chosen to set below what the law requires. That is more substance than most origin claims on a shelf can offer, and it deserves to be said plainly by a competitor.
It also has an edge that no scheme can smooth away. The 2022 file is a reminder that a specification is a promise made in advance about weather that has not happened yet, and that in a dry year on rain-fed hillsides the numbers move. That is not a failure of the designation. It is what farming a real place looks like when someone writes it down honestly.
Our own answer to the same problem is smaller and less formal: one grove, one harvest, no blending, and a refusal to publish a figure we have not measured. Our cold-pressed organic Marrakech olive oil — single-estate, rain-fed, and pressed within hours of harvest — is available to pre-order. First harvest, estimated shipping from November 2026. Fulfilment in the UK, EU, and US.
