Cold Extracted Olive Oil: What It Means and Why It Matters
Cold extracted olive oil is oil produced without heating the olive paste above a set temperature — under European rules, below 27°C — so that the flavour compounds and polyphenols which heat would damage stay in the bottle. It is one of the most meaningful phrases on an olive oil label, and also one of the most misunderstood, sitting alongside "cold pressed", "first cold pressing", and "extra virgin" in ways that are easy to muddle. This article explains exactly what cold extraction is, how it differs from cold pressing and from refining, why the temperature matters, and how to use the term to judge an oil rather than be sold by it.

The Short Answer
- Cold extracted means the oil was separated from the olive paste below 27°C. Under EU and International Olive Council rules, "cold extraction" is a regulated term for modern methods (centrifuge or percolation) kept below that temperature.
- It exists to protect heat-sensitive compounds. Polyphenols, aromas, and flavour degrade with heat, so keeping extraction cool preserves the qualities that make good olive oil worth drinking.
- "Cold extracted" and "cold pressed" mean almost the same thing in practice. The difference is the method: "first cold pressing" refers to traditional press extraction; "cold extraction" to modern centrifugal systems. Both cap the temperature at 27°C.
- It is not the same as "extra virgin". Cold extraction describes the temperature; extra virgin describes the grade and quality. The best oils are both — cold extracted and extra virgin.
- Refined oils are the opposite. "Pure", "classic", and "light" olive oils are made with heat and chemical treatment, which strips most of the polyphenols cold extraction protects.
- Sidr & Stone's olive oil is cold-pressed within hours of a single harvest, unfiltered and extra virgin — exactly the approach this article describes.
What "Cold Extracted" Actually Means
To get oil out of an olive, you crush the fruit into a paste and then separate the oil from the water and solids. How much heat is applied during that separation matters enormously, because olive oil's most valuable components are fragile.
Under European Union labelling rules (Regulation 1019/2002) and International Olive Council standards, two specific terms are protected. "First cold pressing" may be used only for extra virgin or virgin oil obtained at below 27°C by a traditional mechanical pressing system. "Cold extraction" may be used only for extra virgin or virgin oil obtained at below 27°C by percolation or centrifugation — the modern methods most quality producers now use. In both cases the headline fact is the same: the olive paste was never taken above 27°C during extraction.
That 27°C threshold is not arbitrary. It is the line, set by the Codex Alimentarius and the IOC, above which the gentle warming used to coax more oil out of the paste starts to drive off aromatic compounds and degrade polyphenols. Producers can always extract a little more oil by warming the paste further, but they do it at the cost of quality — and they lose the right to the "cold" claim.
Why the Temperature Matters
The case for cold extraction rests on what heat does to olive oil. Three things in particular are at stake.
Polyphenols. Olive oil's antioxidant compounds — oleocanthal, oleuropein, hydroxytyrosol, and tyrosol — are the focus of most of the published research on olive oil, and they are heat-sensitive. Warm the paste and you lose some of them before the oil is even bottled. The EU's registered health claim for olive oil polyphenols (Regulation 432/2012) requires at least 5 mg of hydroxytyrosol and its derivatives per 20 g of oil — a level a well-made cold extracted oil can reach and a heat-treated one struggles to.
Aroma and flavour. The grassy, fruity, peppery character of a good olive oil comes from volatile compounds that, by definition, evaporate. Heat speeds that evaporation. Cold extraction is part of why a freshly made extra virgin oil smells and tastes alive while a heat-treated or refined oil tastes of very little.
Oxidation. Heat accelerates the oxidation that eventually turns any oil rancid. Keeping extraction cool, and pressing quickly after harvest, gives the oil the best possible starting condition for a long, stable shelf life.
None of this makes cold extracted oil a health product — it is a food, and the research describes a dietary pattern, not a cure. But it does explain why the phrase is on the label: it is shorthand for "we did not trade quality for yield".
Cold Extracted vs Cold Pressed: Is There a Difference?
These two phrases cause more confusion than almost any other pair on an olive oil label, and the honest answer is that in everyday terms they mean the same thing: oil separated from the paste without heat, below 27°C.
The distinction is historical and technical. "Cold pressing" — or "first cold pressing" — describes the traditional method, where the paste is spread on mats and squeezed in a hydraulic press. "Cold extraction" describes the modern method, where the paste is spun in a centrifuge or separated by percolation. Most quality producers today use the modern centrifugal method, which is faster, more hygienic, and gives more consistent results — so technically much of the "cold pressed"-style oil you buy is actually cold extracted, the older phrase having simply stuck because shoppers recognise it.
For a buyer, the practical takeaway is simple: treat "cold pressed", "first cold pressing", and "cold extracted" as equally good signs. All three are regulated, all three require the 27°C cap, and all three can only appear on extra virgin or virgin oil. What you are really confirming is that the oil was made gently — the exact machine is a detail.
Cold Extraction Is Not the Same as Extra Virgin
A common mistake is to treat "cold extracted" and "extra virgin" as interchangeable. They describe different things, and understanding the difference is the key to reading a label well.
Extra virgin is a grade. It certifies that the oil was mechanically extracted, has no sensory defects, and sits below 0.8% free acidity — a statement about the finished oil's quality. Cold extracted is a process claim. It certifies that the extraction happened below 27°C — a statement about how the oil was made.
The two usually travel together, because the regulations only allow "cold" claims on virgin and extra virgin oil in the first place. But the logic runs one way, not both. A bottle can be extra virgin without advertising "cold extracted" (though good ones usually were), while "cold extracted" without "extra virgin" would be unusual and worth a second look. The strongest signal is when both appear: an extra virgin oil that is also explicitly cold extracted has told you both that it met the top grade and that it was handled gently to get there.
Contrast all of this with refined oils. Anything labelled simply "olive oil", "pure", "classic", or "light" has been through heat and chemical treatment precisely the opposite of cold extraction — neutralised, bleached, and deodorised — which strips out most of the polyphenols and flavour that cold extraction exists to protect. The word "cold" will never appear on those bottles, and that absence is itself informative.
How to Use the Term When You Buy
Cold extraction is a genuinely useful label cue, but only as part of a fuller picture. On its own it confirms the oil was made gently; combined with a few other checks it points you to a genuinely good bottle.
Look for "extra virgin" alongside the cold claim, since grade and process together are stronger than either alone. Check for a harvest date — cold extraction preserves freshness, but only freshness that was there to begin with, so a recent harvest matters. Favour dark glass or a tin, because the polyphenols you have paid a premium to keep are also degraded by light. And prefer a named single origin over a vague multi-country blend, since traceability tends to travel with care.
One honest caveat: because "cold pressed" and "cold extracted" are familiar, reassuring phrases, some labels lean on them harder than the rest of the bottle deserves. They are regulated and meaningful, but they are not a guarantee of a great oil by themselves — a cold extracted oil that is two years past harvest and sitting in clear glass under shop lights has lost much of the advantage. Read the whole label, not just the comforting word.

- 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 (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 the very claim careful readers should distrust. What we will say is that our oil is single-estate Moroccan, rain-fed, organically grown, and cold-pressed within hours of harvest — and that the evidence of that care is in the taste, the colour, and the season's small limited batch.
Frequently Asked Questions
What does cold extracted olive oil mean?
It means the oil was separated from the olive paste below 27°C, without the warming used to increase yield. Under EU and International Olive Council rules, "cold extraction" is a regulated term for modern percolation or centrifugal methods kept under that temperature.
Is cold extracted the same as cold pressed?
In practice, yes. Both mean the oil was made below 27°C. "First cold pressing" refers to traditional press extraction; "cold extraction" to modern centrifugal methods. Treat all the "cold" terms as equally good signs.
Is cold extracted olive oil the same as extra virgin?
No. Cold extracted describes the temperature of the process; extra virgin describes the grade and quality of the finished oil. The best oils are both — and the "cold" terms can legally appear only on virgin or extra virgin oil.
Why is cold extraction better?
Heat degrades olive oil's polyphenols, aroma, and flavour and speeds oxidation. Keeping extraction below 27°C preserves those heat-sensitive compounds, which is why cold extracted extra virgin oils taste fuller and retain more antioxidants than heat-treated or refined oils.
Does cold extracted olive oil have more polyphenols?
Generally yes, compared with heat-treated or refined oil, because polyphenols survive better at low temperatures. The actual amount also depends on the olive variety, freshness, and storage, so cold extraction helps but isn't the only factor.
Can I cook with cold extracted olive oil?
Yes. Cold extraction refers to how the oil was made, not how you must use it. A cold extracted extra virgin oil is excellent raw and also handles normal home cooking temperatures well, thanks to its monounsaturated fats and antioxidants.
Where can I buy genuinely cold extracted olive oil?
Look for "extra virgin" plus a "cold extracted" or "cold pressed" claim, a recent harvest date, dark glass, and a named origin. Sidr & Stone's single-estate Moroccan oil is cold-pressed within hours of harvest, currently on pre-order, 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
Cold extraction is one of the few phrases on an olive oil label that is both regulated and genuinely meaningful. It tells you the producer kept the paste below 27°C to protect the polyphenols, aroma, and flavour that heat would otherwise strip away — the opposite of how a refined "pure" or "light" oil is made. Understood properly, it sits alongside grade, freshness, packaging, and origin as one of the markers worth checking.
What it is not is a magic word. A cold extracted oil that is old, badly stored, or only "virgin" rather than extra virgin has spent its advantage. The phrase rewards a careful reader who treats it as one signal among several — and, taken that way, it reliably points toward the oils made with care.
Our cold-pressed organic Marrakech olive oil is made exactly this way — pressed cold within hours of a single, patient harvest, unfiltered and extra virgin — and is available now for pre-order, with fulfilment in the UK, EU, and US.
