Cretan Olive Oil: The Island, the Koroneiki and the PDOs
Crete olive oil is the oil most Greek bottles quietly lean on. The island grows its olives on limestone hills between the White Mountains and the Libyan Sea, presses roughly a third of all Greek olive oil according to the Region of Crete, and holds 13 of the 33 Greek olive oil names protected on the European Union's eAmbrosia register. We pulled that register on 2 October 2026 and read the island-wide "Kriti" specification in the Official Journal, rather than repeating what shop listings say. This guide covers the island, the Koroneiki and Tsounati olives behind its oil, every Cretan PDO and PGI, and how to choose a Cretan bottle well.
For our own oil, see our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml). It is Moroccan, not Cretan, and this guide is written so you can judge a Cretan bottle on its own terms.
The Short Answer
- Crete produces about one third of Greece's olive oil, according to a production guide published by the Region of Crete; olive trees cover around 65% of the island's cultivated land, with more than 34 million trees.
- Koroneiki — known locally as "Liani" — dominates the island's groves; Tsounati grows mainly in the mountains of western Crete and Throumbolia in the mountains of central Crete.
- The eAmbrosia register listed 13 Cretan olive oil names on 2 October 2026: 10 Protected Designations of Origin (PDO) and 3 Protected Geographical Indications (PGI), all with the status "Registered".
- The newest is the island-wide "Κρήτη / Kriti" PGI (PGI-GR-02793), registered on 11 September 2025, which requires at least 90% Koroneiki and/or Tsounati olives and caps acidity at 0.6%, against 0.80% for any EU extra virgin oil.
- "Crete" on a label tells you the island; a PDO or PGI name and symbol tells you a specification was followed. Neither tells you how fresh the bottle is — the harvest or best-before date does.
- Sidr & Stone's own oil is a single-estate Moroccan extra virgin from outside Marrakech — a different origin, judged by the same label checks.
Why Crete Matters to Greek Olive Oil
Crete matters because of scale. A guide to producing "Kriti" extra virgin olive oil, prepared by the Institute of Olive Tree, Subtropical Plants and Viticulture and published by the Region of Crete, states that the island produces about one third of Greek olive oil, that olive trees take up 65% of its cultivated area — roughly 190,000 hectares — and that more than 34 million trees are grown there [3].
Greece as a whole is a mid-sized producer by world standards. The International Olive Council's January 2026 statistics put Greek production at a provisional 250,000 tonnes for the 2024/25 crop year, up 30% on the year before, out of a world total of 3,572,000 tonnes [4]. Spain, at 1,419,000 tonnes, dwarfs it. Crete's weight is therefore within Greece rather than on the world stage — but within Greece it is the heavyweight.
The history is long, and the official record is careful about it. The Kriti PGI single document notes an olive tree near the village of Kavousi estimated to be 3,250 years old, an oil press more than 2,500 years old found nearby, and hundreds of recorded monumental trees, including the olive tree of Vouves in Chania [2]. Our guide to Greek olive oil sets Crete in the context of the whole country.
Koroneiki, Tsounati and Throumbolia: Crete's Olives
Cretan olive oil is mostly one cultivar. The Region of Crete's production guide names Koroneiki, Tsounati and Throumbolia as the overwhelming majority of the island's trees, and says Koroneiki dominates farmland across the whole island [3].
- Koroneiki ("Liani") — a small-fruited oil olive; the Kriti PGI single document calls it "the main variety grown in the defined area" and credits it with high oxidative stability [2].
- Tsounati — grown mainly in the mountainous areas of western Crete [3], and the second variety named in the Kriti PGI.
- Throumbolia — grown mainly in the mountainous areas of central Crete [3]; the Kriti specification names Throumba as the main variety in its permitted 10% minor share [2].
The fruit shapes the harvest. Koroneiki carries many small olives that do not fall easily on vibration, so — the single document explains — Cretan growers mainly use hand-held beating machines rather than trunk shakers, and pick when the fruit is turning from greenish yellow to purple-black. The olives travel in jute sacks or crates and, under the Kriti specification's description, are milled within 48 hours of harvest [2]. Our Koroneiki olive oil guide covers the variety in more depth.
All 13 Cretan Olive Oil PDOs and PGIs
Crete holds more protected olive oil names than any other part of Greece. On 2 October 2026 the eAmbrosia register showed 33 Greek entries in class 1.5 (oils and fats), all registered, and 13 of them are Cretan [1]. Ten are PDOs, where every production step must happen in the defined area; three are PGIs, where the link to place is real but at least one step, rather than all, must happen there.

Eight of the 13 date from the first wave of registrations in 1996–1998; Thrapsano, Selino, Messara, Kritsa and Kriti followed between 2002 and 2025. Heraklion, in the centre of the island, holds five of the ten PDOs. For the best-documented of them, our article on Sitia olive oil reads its registration file in detail.
Two register traps worth knowing
The wine with the same name. "Κρήτη" is also a wine PGI (PGI-GR-A1605, registered 16 April 2004), quite separate from the olive oil PGI registered in 2025. When you check a Cretan name on the register, confirm the entry sits in class 1.5, oils and fats, not in the wine register.
EL and GR. Greece appears as "EL" in many EU systems and "GR" in ISO country codes. All 13 Cretan olive oil files use the "GR" prefix; the one Greek olive oil filed under "EL" is Galano Metaggitsiou Chalkidikis (PDO-EL-1027), in northern Greece. Both prefixes mean Greece.
The Kriti PGI: What the Island-Wide Name Requires
The "Κρήτη / Kriti" PGI is the most useful single name for shoppers, because it can cover oil from anywhere on the island. Its single document, published in the Official Journal on 15 April 2025, requires extra virgin olive oil from olives grown in the Region of Crete — the regional units of Chania, Rethymno, Heraklion and Lasithi — of which at least 90% are Koroneiki, Tsounati or both [2]. The olives must be grown and pressed on the island, and the oil bulk-stored and packed there too, to protect it from light, oxygen and heat.
Its chemistry is tighter than the general EU rule for extra virgin olive oil in Annex I of Delegated Regulation (EU) 2022/2104 [5]. The Kriti limits apply at the time of bottling.
| Parameter | Any EU extra virgin olive oil (Reg. 2022/2104, Annex I) | "Kriti" PGI extra virgin (single document, C/2025/2296) |
|---|---|---|
| Free acidity (% oleic acid) | ≤ 0.80 | ≤ 0.6 |
| Peroxide value (meq O2/kg) | ≤ 20.0 | ≤ 15 |
| K232 | ≤ 2.50 | ≤ 2.00 |
| K270 | ≤ 0.22 | ≤ 0.15 |
| Fruitiness (median) | > 0.0 | ≥ 2.5 |
| Bitterness and pungency (median) | Not specified | ≥ 1.0 each |
| Defects (median) | 0.0 | 0.0 |
| Cultivars | Not specified | At least 90% Koroneiki and/or Tsounati |
Two caveats keep the table honest. The limits are checked at bottling, so they say nothing about a bottle that has since sat in a warm shop for a year. And the older Cretan PDOs each have their own specifications — Sitia's, for example, sets its own ultraviolet limits — so the Kriti figures should not be read across to every Cretan name.
What to Buy: How to Read a Cretan Label
Search results for Cretan olive oil are mostly shop listings, so the useful skill is reading what each bottle actually commits to. Six checks, in order:
- Find "extra virgin olive oil". "Olive oil", "light" or "pure" are refined blends, whatever island is pictured.
- Read the origin line. "Greece", "Crete" or a blend statement are different promises.
- Look for a registered name with the EU symbol. "Kriti" PGI, or a PDO such as Sitia Lasithiou Kritis, Kolymvari Chanion Kritis or Messara, means a published specification applies.
- Find the cultivar. Koroneiki for the classic green, peppery Cretan style; Tsounati if the producer names it.
- Check the harvest year or best-before date. Buy the most recent you can find.
- Choose dark glass or a tin, in a size you will finish within a few months of opening.
Applied to bottles UK and US shoppers actually see, the checks separate quite different promises. GAEA's Sitia PDO oil names the PDO, the Koroneiki variety and a stated acidity below 0.8% on its US product page. Belazu's Crete Gold, sold in the UK, says it is made from Koroneiki olives grown in the west of the island, without claiming a designation on its product page. Both can be good oils; only one makes a registered-origin promise. For a producer we have looked at in full, see our review of Terra Creta, and for the same checks on any bottle, our guide to choosing a quality olive oil.
The Honest Objections
"Isn't Cretan olive oil simply the best in the world?"
Some pages ranking for Cretan olive oil say so in their headlines. The register supports a narrower claim: Crete has a dense set of protected names, and its newest PGI sets chemistry limits tighter than EU law. That is real evidence of a serious olive culture. It is not evidence that every Cretan bottle beats every other origin, and no honest guide can rank whole islands.
"Doesn't the Cretan diet prove the oil is good for you?"
Crete is famous in nutrition research because of the Seven Countries Study, which included a cohort of men in Crete [7]. Keys and colleagues, reporting 15-year results in the American Journal of Epidemiology in 1986 for 11,579 men aged 40–59 across 15 cohorts, found all-cause and coronary death rates were low in cohorts with olive oil as the main fat — and stated plainly that causal relationships were not claimed [6]. That is observational evidence about whole populations and diets, not proof about any one bottle. Olive oil is a food, not a medicine.
"You sell Moroccan oil — why write about Crete?"
Because the label skills are the same, and a reader who can read a Cretan bottle can judge ours too. We have no Cretan heritage to claim and would rather say so than borrow one. If a fresh Kriti PGI or Cretan PDO Koroneiki suits your kitchen, it is an excellent choice.
Why Sidr & Stone
This article's argument is that origin is a promise you can check, not an adjective. Sidr & Stone's Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml) makes its origin promise at the narrowest level possible: one farm, our own, on the plains outside Marrakech, Morocco.
- Single-estate — Sidr & Stone's olive oil comes from our own family-owned farm near Marrakech, Morocco, and we control every step from tree to bottle, with no blending across origins.
- Rain-fed — our trees are not irrigated; they take what the season gives.
- Organically grown — no synthetic fertilisers, pesticides or herbicides are used (not yet certified; certification is in progress).
- Single harvest — a small, limited batch, picked when the fruit is ready; the current batch's harvest details are on the product page.
- Cold-pressed within hours of harvest — mechanical extraction only, with no solvents, no refining and no deodorising.
- Unfiltered extra virgin — minimally processed, so it may show natural sediment, which is normal.
- 100% natural — a single ingredient, olive oil, with nothing blended in.
- Dark glass with a gold label — 500ml, in protective packaging against light.
- 10% of profits to charity — a brand-wide commitment.
- Fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is better than a good Cretan oil — a fresh Kriti PGI or Sitia PDO from a careful producer is a fine thing, and the checks above apply to ours as much as theirs. What we will say is that our oil is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest. Unlike a PDO, we hold no registered designation; what we offer instead is one named estate and no blending. For more on our origin, see our guide to Moroccan olive oil.
Frequently Asked Questions
What is Crete olive oil?
Olive oil from olives grown and pressed on the Greek island of Crete, mostly from the Koroneiki variety. Crete produces about a third of Greek olive oil and holds 13 protected olive oil names on the EU register.
Why is olive oil from Crete so well known?
Scale, history and documentation. The island has more than 34 million olive trees, monumental trees thousands of years old, and since 2025 an island-wide "Kriti" PGI with limits stricter than general EU extra virgin rules.
How do I know a Cretan olive oil is genuine?
Look for "extra virgin", a registered name such as Kriti PGI or a Cretan PDO with the EU symbol, a named producer or mill, and a harvest or best-before date. You can check any registered name on the EU's eAmbrosia register.
What is the difference between the Kriti PGI and a Cretan PDO?
A PDO such as Sitia or Messara covers one smaller area and requires every step there. The Kriti PGI covers the whole island, and its specification still requires growing, pressing, storing and packing in the Region of Crete.
Is Cretan olive oil better than Moroccan olive oil?
Neither origin is automatically better. Freshness, cultivar, grade and handling matter more than the place, and a good Cretan or Moroccan extra virgin should both pass the same label checks.
Is Koroneiki olive oil always from Crete?
No. Koroneiki dominates Crete, but it is also grown in Messinia and elsewhere in Greece, and in other countries. The cultivar name tells you the olive; the origin line or registered name tells you the place.
Where can I buy a single-estate extra virgin olive oil?
Look for a producer that names one farm and sells only extra virgin. Our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml) is available to pre-order from the current single-harvest batch, with fulfilment in the UK, EU, and US.
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
Crete olive oil earns its reputation honestly: a third of Greek production, an island planted with Koroneiki, and 13 registered names whose specifications are public — the newest of them, Kriti, stricter than EU law on acidity, peroxide value and ultraviolet absorbance. But "Crete" on a label promises only the island. The information that helps you sits one line further down: the registered name, the cultivar, the harvest date, the grade.
Read those lines and you can choose a Cretan oil well, or compare it fairly with any other origin. That is the same test we invite for our own bottle.
Our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml) — single-estate, rain-fed and cold-pressed within hours of harvest — is available to pre-order now as a limited single-harvest batch, with fulfilment in the UK, EU, and US.
Our extra virgin olive oil is grown organically on our own single-estate farm on the plains outside Marrakech: we control every step from tree to bottle, and no synthetic pesticides, herbicides or fertilisers are used. It is not yet certified organic — certification is in progress, and we will publish it as soon as it comes through.
