Raw Olive Oil: What the Word Guarantees, and What It Doesn't
Raw olive oil is one of those phrases that sounds as though it ought to be a grade — something sitting above extra virgin, the way raw honey sits above the ordinary jar. It isn't. No EU, UK or US olive oil standard uses the word at all, and the reason that matters is more interesting than a simple absence: for olive oil, unlike for honey or milk, almost everything raw is meant to promise has already been written into the legal definition of the grade itself. This article sets out what sellers mean when they use the word, why it is close to redundant on an extra virgin label, the second and quite different sense in which people use it, and how to read a bottle either way.
For our own oil, see our cold-pressed organic Marrakech olive oil.
The Short Answer
- "Raw" has no legal definition for olive oil. It appears in no grade definition and on no list of permitted label claims in the EU, the UK or the United States. Nobody audits it, and nobody can be penalised for using it loosely.
- Extra virgin olive oil is already raw in the only sense that matters. Regulation (EU) No 1308/2013, Annex VII, Part VIII defines virgin olive oils as oils obtained from the olive fruit solely by mechanical or other physical means, which have not undergone any treatment other than washing, decantation, centrifugation or filtration.
- The word is borrowed from raw food and raw honey, where it means nothing heated above roughly 40–49 °C. Olive oil goes further than that already: the terms "cold extraction" and "first cold pressing" are legally capped at 27 °C.
- There is a second, unrelated meaning. Chefs and researchers say "raw olive oil" to mean olive oil eaten uncooked, as a dressing or finishing oil, rather than heated in a pan. That usage is real and useful — and it is what most published research means by the phrase.
- What raw never tells you is how much is in the bottle. It describes handling, not content. A polyphenol figure, a harvest date and a grade tell you more than any adjective.
- Sidr & Stone's olive oil is single-estate, rain-fed, organically grown, unfiltered and cold-pressed within hours of a single harvest — but we do not put the word "raw" on the label, because it would add nothing we have not already said more precisely.
What "Raw Olive Oil" Actually Means
Raw olive oil means oil that has been separated from the fruit without heat and without refining, and bottled more or less as it came out of the mill. That is the intended sense, and it is a perfectly reasonable thing to want. The difficulty is that it is also the legal minimum for anything sold as extra virgin, which makes the word a description rather than a distinction.
The definition is worth reading closely, because it does the work people expect the word "raw" to do. Virgin olive oils, under Regulation (EU) No 1308/2013, Annex VII, Part VIII, are oils "obtained from the fruit of the olive tree solely by mechanical or other physical means under conditions that do not lead to alterations in the oil, which have not undergone any treatment other than washing, decantation, centrifugation or filtration". Extra virgin is that, plus a maximum free acidity of 0.8 g per 100 g expressed as oleic acid and a clean sensory result. The equivalent United States grade, published by the USDA's Agricultural Marketing Service, sets the same 0.8 g per 100 g ceiling and requires a median of defects of zero and a median of fruitiness greater than zero.
Read that list of permitted treatments again — washing, decantation, centrifugation, filtration. There is no heating step to opt out of. An extra virgin oil that had been heat-treated would simply not be extra virgin.
| Term on the label | Who defines it | What it actually guarantees | Sidr & Stone |
|---|---|---|---|
| Raw | Nobody — it appears in no EU, UK or US olive oil standard | Nothing enforceable | Not claimed |
| Extra virgin | Reg. (EU) No 1308/2013, Annex VII, Part VIII; USDA grade standards in the US | Mechanical extraction only, no treatment beyond washing, decantation, centrifugation or filtration; free acidity ≤ 0.8 g per 100 g; no sensory defects | Yes |
| Cold extraction / first cold pressing | Reg. (EU) No 29/2012, Article 5 — assimilated law in Great Britain | Below 27 °C throughout extraction; permitted on virgin grades only | Cold-pressed within hours of harvest |
| Unfiltered | Nobody — descriptive, not regulated | Nothing enforceable; in practice means the fine solids were left in | Yes |
| Polyphenol content (mg/kg) | Voluntary; established by laboratory analysis | A number a reader can actually check — if the producer publishes one | Not published |
Where the Word Came From, and Why It Travels Badly
"Raw" arrived in the food aisle from the raw-food movement, where it has meant, for decades, food never heated above a threshold usually given as somewhere between 40 °C and 49 °C. Raw honey is the version most people meet first: honey that has not been heated or fine-filtered, judged almost entirely on the producer saying so. The word does genuine work there, because ordinary commercial honey usually is warmed and filtered, so the distinction is real.
It also does real work for some seed oils. We have written about this in the context of raw black seed oil, where the raw-food threshold maps neatly onto a cold-press claim below 40 °C — because in that category plenty of oil genuinely is pressed warm or solvent-extracted and then refined, and the word marks a real fork in the road.
Olive oil is the awkward case. The fork in the road already has a signpost on it, and the signpost is stricter. Under Article 5 of Regulation (EU) No 29/2012 — still assimilated law in Great Britain — "first cold pressing" and "cold extraction" may be used only for extra virgin or virgin oils obtained below 27 °C. That is more than ten degrees below the loosest raw-food threshold and comfortably below the tightest. An olive oil that satisfies the legal cold-extraction claim has already cleared the bar "raw" is pointing at, with a number attached and a definition behind it. For the full treatment of that threshold, see our guide to what cold-pressed olive oil actually means.
The Words the Law Defines — and the One It Doesn't
Olive oil labelling is unusually prescriptive. Rather than banning specific claims, the rules set out a short list of optional indications a producer may use, each with a condition attached. Anything not on the list is not a regulated claim at all. The list is short enough to read in full — and "raw" is not on it.
| Optional indication permitted on an olive oil label | Condition attached |
|---|---|
| "First cold pressing" | Extra virgin or virgin only, obtained below 27 °C from a first mechanical pressing using a traditional hydraulic press system |
| "Cold extraction" | Extra virgin or virgin only, obtained below 27 °C by percolation or centrifugation of the olive paste |
| Taste and smell descriptors | Extra virgin or virgin only, and only where based on the results of a formal sensory assessment |
| Maximum acidity | Only if accompanied, in the same size lettering and the same visual field, by peroxide value, wax content and ultraviolet absorption |
| Harvesting year | Only where 100% of the contents of the container come from that harvest |
| "Raw" | Not on the list — no condition, no definition, no enforcement |
None of this makes the word dishonest. A small producer describing their oil as raw is usually telling the truth about how it was made. It simply means the word carries no obligation, and that a reader cannot infer anything from it that the grade has not already promised. The acidity rule in the fourth row is the more instructive one: the law will let a producer print a number, but only if they print the awkward numbers beside it.
The Other "Raw": Olive Oil Eaten Uncooked
There is a second meaning, and in the scientific literature it is the dominant one. When researchers write "raw EVOO" they do not mean an unrefined grade — they mean olive oil that has not been cooked, used as the control against which heated samples are compared. That is also what most cooks mean when they say to use the good oil raw.
The measurements here are worth knowing, because they are frequently exaggerated in both directions. Lozano-Castellón and colleagues, writing in Antioxidants in 2020, pan-fried a Hojiblanca extra virgin oil in a domestic kitchen at two temperatures and measured the phenolic profile by mass spectrometry. Total polyphenol content fell by roughly 40% at 120 °C and roughly 75% at 170 °C compared with the raw oil. That is a real loss. But the authors' own conclusion is the part usually left out: the cooked oil still met the parameters of the EU health claim.
| What was done to the oil | Measured result | Source |
|---|---|---|
| Raw (uncooked) extra virgin olive oil | Baseline polyphenol content | Lozano-Castellón et al., Antioxidants, 2020;9(1):77 |
| Domestic pan-frying at 120 °C | Total polyphenols down about 40% | As above |
| Domestic pan-frying at 170 °C | Total polyphenols down about 75% | As above |
| Cooked oil, overall verdict | Still met the parameters of the EU health claim | As above |
| Repeated deep-frying to the legal polar-compound limit | Olive oils lasted 24–27 hours; a commercial vegetable oil blend lasted 15 hours | Casal et al., Food Chem Toxicol, 2010;48(10):2972–9 |
The Casal study is the useful counterweight. Sampling every three hours until total polar compounds reached the maximum legal value of 25%, the Porto group found that every olive oil category outlasted the vegetable oil blend it was compared against — 24 to 27 hours against 15. Their conclusion was that olive oil is "clearly resistant to frying conditions", and that the natural antioxidant content is what predicts how it behaves.
Both are single studies with the limits that implies: one cultivar in one kitchen, one set of oils in one laboratory. Neither licenses the claim that cooking with extra virgin oil is pointless, and neither licenses the opposite. The honest reading is that heat costs you polyphenols in proportion to how hot you go, and that using some of a good oil uncooked is a sensible way to keep the most of it. For what those compounds actually are, see our guide to olive oil polyphenols.
Three Objections Worth Taking Seriously
"If the word is redundant, why does anybody use it?" Mostly because it is doing a different job than the one it appears to be doing. For many small sellers, "raw" is shorthand for unfiltered — oil bottled without the final polish, sediment and all. That is a genuine choice with genuine trade-offs, and we cover it properly in our comparison of unfiltered and filtered olive oil. The criticism is not that the word is a lie; it is that "unfiltered" says the same thing more precisely, and can be checked by looking at the bottle.
"But the extra virgin grade is widely abused — so the legal definition proves nothing." This is the strongest objection and it deserves a straight answer: yes, misgraded oil is a real and documented problem, and pointing at a definition is not the same as verifying that a particular bottle meets it. What the objection does not do, though, is rescue the word "raw". If a producer is prepared to misdescribe a regulated grade that carries penalties, an unregulated adjective is not going to slow them down. If anything the incentive runs the other way. We look at what genuine verification does and doesn't establish in our piece on real olive oil.
"Doesn't unfiltered oil go off faster?" It can. Suspended fruit solids and residual moisture give an unfiltered oil more to react with over time, which is why an unfiltered bottle rewards a cool dark cupboard and a reasonable turnover rather than being kept for a special occasion two winters away. That is a real cost, honestly stated. It is also the main reason a single-harvest oil is best treated as a seasonal thing.
How to Buy Well When the Label Says "Raw"
Treat the word as a hint about the producer's intentions and then go looking for the things that can actually be checked. Four in particular carry more information than any adjective.
- The grade, stated plainly. "Extra virgin olive oil" on the front is the one claim on the bottle that carries a legal definition and a legal consequence.
- A harvest date, not just a best-before date. Under the labelling rules a harvest year may only be shown if the entire container comes from that harvest, which makes it one of the more reliable things printed on a bottle.
- Numbers, if the producer publishes any. Free acidity, peroxide value and polyphenol content are measured, not asserted. Most producers publish none of them — that is the category norm rather than a black mark — but the ones who do have given you something to hold them to.
- Dark glass or a tin. Light degrades the polyphenols that all of this is ultimately about. A clear bottle under shop lighting undoes a good deal of careful milling.

Why Sidr & Stone
This article has argued that adjectives are worth less than definitions and measurements, which puts an obligation on us to describe our own oil the same way. We do not print the word "raw" on our label. Everything it would be gesturing at is already covered by words that mean something specific.
- Single-estate — one family-owned grove near Marrakech, Morocco; no blending across origins
- Rain-fed — no irrigation; the trees take what the season gives
- Organically grown — no synthetic fertilisers, pesticides, or herbicides
- Single harvest — small, limited batch; once the season's pressing is gone, it's gone until next year
- Cold-pressed within hours of harvest — flavour, aroma, and polyphenols preserved
- Unfiltered extra virgin — minimally processed, may show natural sediment
- 100% natural — single ingredient, no additives
- Dark glass with gold label — protective packaging against light
- Halal certified
- 10% of profits to charity — a brand-wide commitment
- Fulfilment in the UK, EU, and US
One thing we are not able to give you yet, and would rather say plainly than skate over: we do not publish a polyphenol figure for our olive oil. Laboratory analysis for the first harvest has not been done, and until it has, a number from us would be an estimate dressed up as a measurement. When we have one, it will go on the site with the certificate behind it.
We will not tell you Sidr & Stone is the best olive oil, or the rawest one — that would be exactly the unbacked adjective this article has spent two thousand words arguing against. What we will say is that our oil is single-estate Moroccan, rain-fed, organically grown, unfiltered, and cold-pressed within hours of a patient harvest, and that the evidence of that care is in the colour, the taste, and the size of the season's batch.
Frequently Asked Questions
What is raw olive oil?
Raw olive oil is a marketing description for oil pressed and bottled without heat treatment or refining. It has no legal definition in the EU, the UK or the United States. In practice it usually means an extra virgin oil that is also unfiltered — which is what the label would be better off saying.
Is raw olive oil the same as extra virgin?
Almost. Extra virgin is a legal grade requiring mechanical extraction with no treatment beyond washing, decantation, centrifugation or filtration, plus free acidity no higher than 0.8 g per 100 g and no sensory defects. That already excludes everything "raw" is meant to rule out, so a genuine extra virgin oil is raw whether or not the word appears.
Is there a legal definition of raw olive oil?
No. The word appears in no olive oil grade definition and on no list of permitted optional label indications in the EU, the UK or the United States. Producers may use it freely, and no authority checks it.
Is raw olive oil better than cold-pressed olive oil?
Cold-pressed is the stronger claim, which is the reverse of what most people assume. "Cold extraction" and "first cold pressing" are restricted by law to virgin grades extracted below 27 °C. "Raw" borrows a looser threshold from the raw-food convention, roughly 40–49 °C, and is not enforced at all.
Does cooking with olive oil destroy the polyphenols?
It reduces them in proportion to the heat. In a 2020 study in Antioxidants, domestic pan-frying cut total polyphenols by about 40% at 120 °C and about 75% at 170 °C compared with the raw oil — but the cooked oil still met the parameters of the EU health claim. Using some of a good oil uncooked is a sensible way to keep more of it.
Why is my raw olive oil cloudy?
Because it is unfiltered. Cloudiness and a little sediment at the bottom are suspended fruit solids left in when the oil was bottled, and are entirely normal. They do mean the oil is best kept cool and dark and used within a reasonable window rather than saved indefinitely.
Where can I buy genuinely unprocessed olive oil?
Look for an oil that states the extra virgin grade, a harvest year, a named single origin and dark glass or tin packaging, and buy from a producer who will tell you when it was pressed. Sidr & Stone's single-estate Moroccan oil is cold-pressed within hours of harvest and bottled unfiltered; it is available to pre-order. First harvest, estimated shipping from November 2026. 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
Raw is a decent instinct expressed as a poor word. The instinct — that you want the oil interfered with as little as possible between the tree and the table — is exactly right, and it is the instinct the whole extra virgin category was built to serve. The word simply arrives late to a job already done, and done with numbers attached: mechanical extraction only, no treatment beyond washing, decantation, centrifugation or filtration, and a 27 °C ceiling on anything calling itself cold extracted.
The second meaning is the one worth keeping. Olive oil used uncooked really does deliver more of what makes it interesting, and the measured difference between raw and pan-fried oil is large enough to change how you use a good bottle without being large enough to justify never cooking with it at all.
If a label tells you it is raw and nothing else, you have been given an adjective. If it tells you the grade, the harvest, the origin and how it was extracted, you have been given something you can check.
Our cold-pressed organic Marrakech olive oil is made that way — single-estate, rain-fed, organically grown, unfiltered extra virgin, pressed cold within hours of a single patient harvest — and is available to pre-order. First harvest, estimated shipping from November 2026. Fulfilment in the UK, EU, and US.
