Greek Olive Oil: Regions, Cultivars and What the Label Guarantees
Greek olive oil is one of the most trusted phrases in the olive aisle, and one of the least explained. Greece grows olives from Crete to Thrace, presses much of its oil from one small-fruited cultivar, and has 33 olive oil names registered as protected designations on the European Union's eAmbrosia register — 20 PDOs and 13 PGIs, the newest of them the island-wide "Kriti" PGI added in September 2025. We pulled the full register on 1 October 2026 [1] and read the published specifications rather than repeating other guides. This article explains the regions, the cultivars, and exactly what the word "Greek" on a label does — and does not — guarantee under EU marketing rules.
For our own oil, see our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml). It is a Moroccan oil, not a Greek one, and this guide is written so you can judge a Greek bottle on its own terms.
The Short Answer
- On an extra virgin or virgin olive oil, "Greece" as the place of origin means the olives were harvested in Greece and pressed at a mill in Greece — that is the legal rule in Commission Delegated Regulation (EU) 2022/2104.
- The eAmbrosia register lists 33 Greek olive oil designations on 1 October 2026: 20 Protected Designations of Origin (PDO) and 13 Protected Geographical Indications (PGI), all with status "Registered".
- Crete holds 13 of the 33, including the island-wide "Kriti" PGI registered on 11 September 2025; the Peloponnese holds Kalamata, Lakonia, Olympia and several smaller names.
- Koroneiki is the backbone cultivar. The Kriti PGI requires at least 90% Koroneiki or Tsounati olives, and the Kalamata PDO is made mainly from Koroneiki with no more than 5% Mastoeidis.
- A PDO or PGI ties an oil to a place and a specification — Kriti, for example, caps acidity at 0.6% against the EU's 0.8% for any extra virgin oil. It does not tell you how fresh the bottle is.
- "First cold pressing" and "cold extraction" are legally reserved terms meaning extraction below 27°C; a harvest year may only be printed if 100% of the oil comes from that harvest.
- Sidr & Stone's own oil is a single-estate Moroccan extra virgin from outside Marrakech — a different origin, judged by the same label checks.
What "Greek Olive Oil" Means on a Label
Greek olive oil, legally, is olive oil whose olives were harvested in Greece and pressed in a Greek mill. Under Article 8 of Commission Delegated Regulation (EU) 2022/2104 [4], extra virgin and virgin olive oils must state a place of origin, and a named Member State must match both where the olives were harvested and where the mill stands.
That rule closes the most obvious loophole. If olives grown in one country are pressed in another, the regulation requires wording of the form "extra virgin olive oil obtained in [country] from olives harvested in [country]". Blends must say so: "blend of olive oils of European Union origin", "not of European Union origin", or both. A registered PDO or PGI can stand in place of a country as the stated origin.
What the rule does not cover is everything after the mill. The country of origin says nothing about who bottled the oil, when it was pressed, or how it was stored. In Great Britain, the older EU marketing standard — Regulation (EU) No 29/2012 — continues as assimilated law, with its own version of these origin rules, so a UK bottle may follow slightly different wording.
The Main Greek Olive Oil Regions
Greece's registered olive oil names cluster in the south and the islands. Of the 33 on the register, the regional spread looks like this.
| Region | Registered names (file number) | Main cultivars named in specifications we read |
|---|---|---|
| Crete | 13 names, including Kriti (PGI-GR-02793), Sitia Lasithiou Kritis (PDO-GR-0052), Chania Kritis (PGI-GR-0033), Kolymvari Chanion Kritis (PDO-GR-0053), Peza Irakliou Kritis (PDO-GR-0035) and Messara (PDO-GR-0973) | Koroneiki and Tsounati, with Throumba as the main minor variety (Kriti PGI) |
| Peloponnese | Kalamata (PDO-GR-0037), Lakonia (PGI-GR-0457), Olympia (PGI-GR-0034), Krokees Lakonias (PDO-GR-0407), Finiki Lakonias (PDO-GR-0361), Petrina Lakonias (PDO-GR-0394), Kranidi Argolidas (PDO-GR-0400), Lygourio Asklipiou (PDO-GR-0050) | Koroneiki, up to 5% Mastoeidis (Kalamata PDO) |
| Aegean and Ionian islands | Lesvos / Mytilini (PGI-GR-0059), Samos (PGI-GR-0032), Thassos (PGI-GR-0377), Rodos (PGI-GR-0390), Kefalonia (PGI-GR-0388), Zakynthos (PGI-GR-0051), Agios Mattheos Kerkyras (PGI-GR-0214) | On Lesvos: local Kolovi and Adramytiani alongside Koroneiki (research literature) |
| Northern and western mainland | Agoureleo Chalkidikis (PDO-GR-0736), Galano Metaggitsiou Chalkidikis (PDO-EL-1027), Elaiolado Makris (PDO-GR-02388), Preveza (PGI-GR-0399) | Varies by designation |
Crete is the heavyweight. The Kriti PGI single document, published in the Official Journal on 15 April 2025, describes Koroneiki as "the main variety grown in the defined area" and notes the olives are milled within 48 hours of harvest [2]. The Peloponnese gives the world its most famous Greek oil name — our guide to Kalamata olive oil explains why that oil is not made from Kalamata table olives. Lesvos, in the North Aegean, is one of Greece's largest olive-growing islands, and a 2021 study in Molecules by Kalogiouri and colleagues records the local Kolovi and Adramytiani varieties grown there alongside Koroneiki [5].
The Cultivars: Koroneiki and the Rest
Greek olive oil is less varied than the map suggests, because one cultivar does most of the work. Koroneiki is a small-fruited oil olive, and the Kriti PGI specification credits it with "high oxidative stability" — the reason Cretan harvesters use hand-held beating machines rather than tree shakers, since its many small olives do not fall easily on vibration. Our Koroneiki olive oil guide covers the variety in depth.
- Koroneiki — the dominant oil cultivar of Crete and Messinia; green, fruity and peppery in style.
- Tsounati — the second named variety in the Kriti PGI, permitted alone or blended with Koroneiki up to the 90% threshold.
- Throumba — named in the Kriti PGI as the main variety in the permitted 10% minor share; better known as a wrinkled, tree-ripened table olive.
- Mastoeidis — capped at 5% in Kalamata PDO oil under the specification published in 2012.
- Kolovi and Adramytiani — the local Lesvos varieties; Kalogiouri and colleagues measured total phenols in Kolovi extra virgin oils from Lesvos between 251 and 1,230 mg/kg [5].
That last range is worth reading carefully. It comes from one study of one variety on one island, and the four-fold spread between samples shows how much harvest, altitude and handling matter. A cultivar name is a starting point, not a polyphenol guarantee — our explainer on olive oil polyphenols covers what those figures mean.
PDO and PGI: What a Registered Greek Name Adds
A protected name is the strongest origin promise a Greek bottle can carry. The eAmbrosia register — the European Commission's database of geographical indications — showed 33 Greek entries in the oils-and-fats class on 1 October 2026, all of them olive oils, all with the status "Registered". Twenty are PDOs, where every production step must happen in the defined area; thirteen are PGIs, where the link to place is real but at least one step, rather than all, must happen there. Twenty-two of the 33 were registered between 1996 and 1998; Kriti, approved by the Commission on 11 September 2025, is the newest [6].
Each name has a published specification, and those specifications can be far stricter than general EU law. The Kriti PGI is the clearest example, because its full single document is in the Official Journal.
| Parameter | Any EU extra virgin olive oil (Reg. 2022/2104, Annex I) | "Kriti" PGI extra virgin (single document, C/2025/2296) |
|---|---|---|
| Free acidity | ≤ 0.80% | ≤ 0.6% |
| Peroxide value | ≤ 20 meq O2/kg | ≤ 15 meq O2/kg |
| K232 | ≤ 2.50 | ≤ 2.00 |
| K270 | ≤ 0.22 | ≤ 0.15 |
| Fruitiness (median) | > 0 | ≥ 2.5 |
| Defects (median) | 0 | 0 |
| Cultivars | Not specified | At least 90% Koroneiki and/or Tsounati |
| Where it must be made | Not specified beyond origin labelling | Grown, pressed, stored and packed in the Region of Crete |
The Kalamata PDO adds its own limits: the amendment application published in the Official Journal in 2012 defines the area as the whole of Messinia and sets maximum acidity at 0.50 g per 100 g [3]. One register quirk catches careful readers: Greece appears as "EL" in some EU systems and "GR" in others, and the register files Galano Metaggitsiou Chalkidikis under PDO-EL-1027 while the other 32 Greek olive oil numbers use "GR". Both refer to Greece.
What the Label Guarantees — and What It Doesn't
Every phrase on a Greek bottle is either a legal promise, a reserved term with a technical definition, or marketing. Knowing which is which is most of the skill.
| Label wording | What it legally guarantees | What it does not tell you |
|---|---|---|
| "Extra virgin olive oil" | Top grade, obtained directly from olives solely by mechanical means, within the Annex I chemical and tasting limits | How fresh the oil is today |
| "Greece" as origin | Olives harvested in Greece and pressed in a Greek mill | Which region, cultivar or producer |
| PDO or PGI name and symbol | The registered area and the published specification | Whether this bottle is recent or well stored |
| "First cold pressing" | Below 27°C, from a first mechanical pressing using traditional hydraulic presses | Anything about quality beyond the method |
| "Cold extraction" | Below 27°C by percolation or centrifugation | Anything about the olives themselves |
| Harvest year | 100% of the contents come from that harvest | How the oil was stored since |
| Maximum acidity figure | Only lawful if peroxide, wax and UV values are printed alongside it | Taste or polyphenol content |
Two of these trip up even experienced buyers. "First cold pressing" is the term most often seen on supermarket shelves, yet Article 10 of Regulation 2022/2104 reserves it for oil from traditional hydraulic presses; many modern mills use centrifuges, for which the correct term is "cold extraction". And an acidity figure printed on its own is not allowed, because acidity means little without the other measures beside it.
How to Buy a Good Greek Olive Oil
Six checks separate a well-chosen Greek bottle from a merely Greek one.
- Find "extra virgin" — not "olive oil", "light" or "pure", which are refined blends.
- Read the origin line — "Greece" alone, a named PDO or PGI, or a blend statement.
- Look for the PDO or PGI symbol with the registered name, if regional origin matters to you.
- Find the cultivar — Koroneiki for a classic green, peppery style; Kolovi or Tsounati for something less common.
- Check for a harvest year or a best-before date, and 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.
For a fuller walkthrough of these checks on any bottle, see our guide to choosing a quality olive oil, and for how the Greek rules compare with other origins, our guides to Italian olive oil and Spanish olive oil.
The Honest Objections
"Isn't a PDO a guarantee of quality?"
It is a guarantee of origin and of a specification, and some specifications — Kriti's 0.6% acidity cap is one — are genuinely demanding. But the limits apply at bottling. A PDO bottle that has sat in a warm shop window for a year can be worse than a fresh, unregistered oil. Treat the designation as a floor, then check the date.
"Greece has the best olive oil, surely?"
Greece has a deep olive culture: the European Commission puts Greek consumption at around 12 kg per person per year, the highest in the EU [7]. That is real evidence of how central the oil is to Greek cooking. It is not evidence that every Greek bottle beats every other origin, and no honest guide can rank whole countries.
"You sell Moroccan oil — why write about Greek oil?"
Because the label skills are the same, and a reader who knows how to read a Greek bottle can judge ours too. We have no Greek heritage to claim and would rather say so than borrow one. If a fresh Cretan Koroneiki from a named mill 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 — 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 Greek oil — a fresh PDO from a careful Cretan or Messinian producer is a fine thing, and the label 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. For more on our origin, see our guide to Moroccan olive oil.
Frequently Asked Questions
What is Greek olive oil?
Olive oil from olives harvested and pressed in Greece. Koroneiki is the main variety on Crete and in Messinia, and 33 Greek olive oil names are protected as PDOs or PGIs on the EU register.
Why is Koroneiki so common in Greek olive oil?
It is the main variety grown on Crete and in Messinia, and the Kriti PGI specification credits it with high oxidative stability. Together with Tsounati it must make up at least 90% of Kriti PGI oil, and it is the main variety in Kalamata PDO oil.
How can I tell if a Greek olive oil is genuine?
Check that the origin line says Greece or names a registered PDO or PGI, look for the EU designation symbol, and buy from a producer or mill that is named on the label.
What is the difference between PDO and PGI Greek olive oil?
A PDO requires every production step in the defined area. A PGI requires at least one step there, though some specifications, like Kriti's, require growing, pressing and packing in the area anyway.
Is Greek olive oil better than Moroccan olive oil?
Neither origin is automatically better. Freshness, cultivar, grade and handling matter more than the country, and a good Greek or Moroccan extra virgin should both pass the same label checks.
What does "first cold pressed" mean on Greek olive oil?
Under EU rules it means extraction below 27°C from a first pressing with traditional hydraulic presses. Oil made in modern centrifuge mills below 27°C should say "cold extraction" instead.
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
Greek olive oil earns its reputation honestly: a deep olive culture, a backbone cultivar in Koroneiki, and 33 registered names whose specifications are public and, in places, stricter than EU law. But the word "Greek" on its own promises only where the olives were grown and pressed. The useful information sits one line further down — the PDO or PGI, the cultivar, the harvest year, the grade.
Read those lines and you can choose a Greek 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.
