Minerva Olive Oil: The Greek Range, Brand by Brand and Grade by Grade
If you are looking at Minerva olive oil, the first useful thing to know is that you are not looking at one product. You are looking at eleven, sold under three different brand names, at two different grades, in sizes from a 500 ml bottle to a four-litre tin. The company behind them is one of the larger food manufacturers in Greece, and it has been in the olive oil trade a long time. Most of what is written about the brand online treats it as a single thing and stops there. This article does the boring, useful work instead: which company you are buying from, what each line actually declares, what none of them publishes, and the one word on the pack that changes what you are holding.

The Short Answer
- Minerva olive oil is made by Minerva S.A., a Greek food company based at Tatoiou 165 and Odysseos, 14452 Metamorfosi, Attica. Its own homepage describes it as starting out in the Greek market in the olive oil sector in the early 1900s and becoming one of the largest food companies in the country.
- The olive oil is sold under three brand names, not one: Minerva, Altis and Horio. All three sit inside the same company, alongside eleven further brands covering butters, margarines, tomato products, sauces, vinegars, cooking fats and cheese.
- Two of the lines are not extra virgin, and the product name says so. Minerva Classic Olive Oil and Altis Classic Olive Oil are named "olive oil", not "extra virgin olive oil", and the company describes Altis Classic on its own page as "a sweet mixture of selected olive oils".
- Where the company does declare things, it declares real ones. Two lines name Koroneiki as a single variety, and two carry the PDO Kalamata designation — a genuine, registered origin name, not a marketing word.
- No Minerva olive oil page publishes a chemical figure. We crawled all 371 URLs in the company's own sitemaps and every PDF it links to before writing that sentence — the method is set out below. This is the category norm rather than a fault, and it is worth saying that Sidr & Stone does not publish a polyphenol figure either.
- Sidr & Stone is a different shape of product entirely: one single-estate, rain-fed, organically grown Moroccan grove, one small harvest a season, cold-pressed within hours and bottled unfiltered in 500ml dark glass.
Which Minerva Are You Looking For?
"Minerva" is a Roman goddess and a popular company name, so it pays to be sure. Within olive oil specifically there are two entities a search can land on, and they are not related.
The one almost everyone means is the Greek company at minerva.com.gr. That is the live domain we used throughout this article, and every fact attributed to the company below comes from a page we fetched there on 26 August 2026. The site runs on WordPress with a WPML translation layer and Yoast sitemaps; it is not a WooCommerce shop, and it does not sell direct.
The second is Minerva Evo, a small Sicilian producer selling single-harvest extra virgin olive oil in tins by harvest year. Its site is a Shopify store, and when we checked it returned "This store is currently unavailable" rather than a shopfront. We mention it only so that a reader who arrived here looking for a Sicilian tin knows they have the wrong article.
| Name | What it is | Where | Related to the other? |
|---|---|---|---|
| Minerva S.A. | Greek food manufacturer; olive oil plus butters, margarines, tomato products, sauces, vinegars, cooking fats and cheese | Metamorfosi, Attica, Greece | This is the one nearly all searches mean |
| Minerva Evo | Premium Sicilian single-harvest extra virgin olive oil sold in tins by harvest year | Italy | No connection; its shop was offline when we checked |
| "Minerva" in other sectors | A common company name used by unrelated businesses outside food | Various | No connection |
The Olive Oil Range, Brand by Brand
Minerva S.A. runs fourteen brands. Three of them carry olive oil: Minerva itself, Altis and Horio (Χωριό, meaning "village"). The rest — TOP, Pummaro, Benecol, BRAVA, Fast, Minervini, Mana, Flora, Minerva "Niki", Sol and Savoi — cover everything from balsamic cream to feta.
This matters more than it sounds. If you buy a bottle labelled Altis and a bottle labelled Horio thinking you are comparing two producers, you are not; you are comparing two ranges from the same company. And because the three brands overlap in grade, the brand name on the front tells you very little on its own. The line name does the work.
| Brand | Line | What the product name says about grade | What the company declares on the page | Sizes listed |
|---|---|---|---|---|
| Minerva | Classic Olive Oil | "Olive oil" — not extra virgin | "The first olive oil in Greece that came in standardized packaging" (their words) | 1 L, 2 L, 4 L |
| Minerva | Greek Extra Virgin Olive Oil Koroneiki | Extra virgin | Single variety, Koroneiki | 500 ml, 750 ml |
| Minerva | Organic Extra Virgin Olive Oil | Extra virgin | Organic; "rigorous standards at every point of the manufacturing process" | 500 ml, 750 ml |
| Minerva | P.D.O. Kalamata Extra Virgin Olive Oil | Extra virgin, PDO | Selected olives from the Messinian valley in the south-western Peloponnese | 500 ml, 750 ml |
| Altis | Classic Olive Oil | "Olive oil" — not extra virgin | "A sweet mixture of selected olive oils with a discrete aroma of mature fruits" | 1 L, 2 L, 3 L |
| Altis | Organic extra virgin olive oil | Extra virgin | Organic certification named on the page | 1 L, 2 L |
| Altis | Early Harvest (Agourelaio) | Extra virgin | Early harvest | 750 ml |
| Horio | PDO Kalamata olive oil | Extra virgin, PDO | "The long-standing olive variety of the Messinian land"; mechanical methods only | 1 L |
| Horio | Koroneiki variety | Extra virgin | Produced solely from Koroneiki variety olives | 750 ml, 1 L, 2 L, 4 L |
| Horio | Mountain regions | Extra virgin | Olives grown in mountain regions; "rich, full-bodied, intense flavor" | 1 L, 2 L |
| Horio | Organic extra virgin olive oil | Extra virgin | Organic | 750 ml |
Two things in that table are worth crediting plainly. Naming Koroneiki as a single variety on two separate lines is a real disclosure — plenty of national brands never name a cultivar at all, and Koroneiki is the small, hardy olive that carries most of Greek extra virgin production. And carrying PDO Kalamata on two lines is a legally protected origin claim, not a slogan: the designation sits in the EU register as PDO-GR-0037, protected on 13 June 1997, with Koroneiki and Mastoidis as its permitted varieties. We go through what that name does and does not guarantee in our piece on Kalamata olive oil, and another Greek brand built almost entirely on the same designation is covered in our article on Iliada olive oil.
"Classic" Is a Grade, Not a Compliment
This is the single most consequential thing on a Minerva or Altis shelf, and it is hiding in plain sight.
EU retail law recognises four consumer designations for olive oil: extra virgin olive oil, virgin olive oil, olive oil composed of refined olive oil and virgin olive oils, and olive-pomace oil. Only the first two are unrefined. The third — the one most packs shorten to plain "olive oil" — is a blend in which refined oil, stripped of most of its flavour and much of its phenolic content by industrial processing, is cut back with a proportion of virgin oil to restore some taste. The conformity rules and analytical limits behind those designations now live in Regulations (EU) 2022/2104 and 2022/2105, the instruments that replaced the long-repealed Regulation (EEC) No 2568/91.
Minerva Classic Olive Oil and Altis Classic Olive Oil are named olive oil. Their extra virgin siblings say extra virgin olive oil in the product name. The company is not hiding anything here — it describes Altis Classic on its own page as "a sweet mixture of selected olive oils with a discrete aroma of mature fruits, resulting in a fine, mellow flavor", which is an accurate description of what a blended everyday oil tastes like. The mistake is entirely on the buying side: shoppers see a familiar Greek brand, a large tin and the reassuring word "classic", and read extra virgin into a pack that never claimed it.
None of that makes the Classic lines bad. They are the biggest sizes for a reason — they are everyday cooking oil, sold by the litre for people who fry, roast and bake in quantity, and judged as that they are a sensible product. The error is only ever paying extra-virgin attention, or extra-virgin expectations, to a bottle that told you plainly it was something else. If you want the full walkthrough of what that word is doing, our article on classic olive oil covers the designation in detail.
What Minerva Declares — and What Nobody in the Aisle Declares
Before writing a sentence about what a company does not publish, we go and look where the number would live. Here is exactly what we did.
We pulled every URL listed in minerva.com.gr's own sitemaps — the product, page, brand and blog sitemaps — giving 371 unique URLs, including all 220 product pages across both the Greek and English versions of the site. We fetched every one of them and searched the raw HTML for acidity, οξύτητα, polyphenol, πολυφαιν, mg/kg, peroxide, υπεροξειδ, K232, K270, K268 and free fatty. Fourteen pages matched. Every single one was either a TOP-brand vinegar page, where the figure is the vinegar's 5% or 6% acidity, or a general blog post. Not one olive oil product page carries a chemical figure of any kind.
We also collected every PDF the site links to anywhere: 24 files, all of them annual financial statements or privacy policies. There is no technical or trade area, no downloadable specification, no certificate of analysis. The company's WooCommerce Store API returns 404 because the site is not a shop, so there is no product feed to interrogate either.
So the honest finding is this: Minerva publishes no free acidity, peroxide value, K-coefficient, polyphenol figure or harvest date for any of its olive oils. What it does publish is cultivar on two lines, a registered PDO on two lines, an organic claim on three, and a size range.
That is not a scandal, and we are not going to dress it up as one. It is the category norm. Across dozens of producers we have examined for this blog — Spanish, Italian, Greek, Californian and Tunisian, small estates and national brands alike — the overwhelming majority publish no lot chemistry at all. A handful are genuine exceptions, and they deserve the credit: some publish full third-party sensory and chemical certificates per lot, which is the highest standard we have found anywhere. Most publish nothing, and Sidr & Stone publishes no polyphenol figure either. We say that in every article rather than letting the omission pass quietly.
One point of precision, because it is so often garbled. There is a single polyphenol figure with legal force in the EU: 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. Minerva makes no such claim, which is the correct thing to do in the absence of a measurement.
One more thing we looked at and could not use. The company's own "Awards and Certifications" page lists four product awards — two for Horio feta at the World Cheese Awards in 2019 and 2020, two for Horio pralina at a healthy-food award in 2019 — and then terminates in a WordPress critical error, in both the English and the Greek versions. No certification standard is named on the part that renders. Because the page is visibly broken, we do not know what sits below the error, and we publish nothing from it.
Three Claims Worth Reading as the Company's Own Words
Minerva makes three superlative claims on its product pages. None is dishonest on its face; all three are the kind of statement that gets repeated by third parties until it hardens into fact. We report them as the company's own words and leave them there.
"Probably why it is the No1 Extra Virgin olive oil brand in Greece." This appears on the Minerva Koroneiki page. No measure, source or year is given, and we found none. It may well be true by volume; we simply cannot check it, so we will not repeat it as a finding.
"This was the first olive oil in Greece that was named a premium extra virgin olive oil with Protected Designation of Origin." This is on the Minerva P.D.O. Kalamata page. It is worth putting the register alongside it rather than contradicting it: the Kalamata designation itself was protected on 13 June 1997, whereas four Greek olive oil PDOs — Peza Irakliou Kritis, Vorios Mylopotamos Rethymnis Kritis, Viannos Irakliou Kritis and Arxanes Irakliou Kritis — were protected on 21 June 1996, a year earlier, along with the Chania Kritis and Olympia PGIs. The claim may well be about this specific bottled product reaching the Greek market first rather than about the designation, which is a different and unrecorded question. Either way, the register does not support reading it as "the first Greek olive oil PDO".
"This was the first olive oil in Greece that came in standardized packaging." On the Minerva Classic page. Plausible for a company that says it entered the trade in the early 1900s, and not something any public record we could reach either confirms or refutes.
Three Objections Worth Answering
"A big national brand cannot be as good as a small estate." Not a safe assumption, and scale is not a quality verdict. A large company with its own mills and steady contracts can hold a specification more consistently than a small producer having a bad year. What scale genuinely costs you is traceability to one place: a national range draws fruit from many groves, so the oil in the bottle is a competent blend rather than a portrait of a particular hillside. Whether that matters depends entirely on what you want the oil to do.
"If they publish no chemistry, they must be hiding something." We do not think so, and the evidence points the other way. Publishing per-lot analysis is rare across the whole category, including among producers with excellent oil and nothing to hide; it is a cost and a commitment most bottlers have never made. The fair reading is that Minerva sits with the majority, not that it has something to conceal. We would rather campaign for the whole category to publish more than single out one company for a norm — particularly when we do not publish a polyphenol figure ourselves.
"You sell olive oil, so of course you say the Classic line is inferior." We have not said that. A blend of refined and virgin oil is a legitimate product with a legitimate job, and for high-volume cooking it is often the sensible buy. The only genuine error is paying for one thing and believing you bought another — and on these packs the product name tells you honestly which one it is. Our disagreement is with shoppers not reading it, not with Minerva printing it.
Why Sidr & Stone
We are the opposite shape of producer, and the comparison is only useful if that is said clearly. Minerva is a national range with three brand names and eleven olive oil lines. We have one grove and one oil.
- 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. Where a competitor holds a genuine organic certification, as several Minerva lines do, that is a real advantage we do not match.
- 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 is exactly the sort of claim this article has spent its length taking 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 Minerva olive oil?
Minerva olive oil is a range of Greek olive oils made by Minerva S.A., sold under the Minerva, Altis and Horio brand names. It spans everyday blended cooking oil in large tins through to single-variety and PDO Kalamata extra virgin oils in 500 ml and 750 ml bottles.
Who makes Minerva olive oil?
Minerva S.A., a Greek edible-oils and food company based at Tatoiou 165 and Odysseos in Metamorfosi, Attica. Alongside olive oil it makes butters, margarines, tomato products, sauces, vinegars, cooking fats and cheese under fourteen brands in total.
Is Minerva olive oil extra virgin?
Some of it. Nine of the eleven olive oil lines are named extra virgin. Two — Minerva Classic Olive Oil and Altis Classic Olive Oil — are named simply "olive oil", which in EU retail law means a blend of refined and virgin oils. Read the product name on the pack.
What is the difference between Minerva, Altis and Horio?
They are three brands owned by the same company rather than three producers. Ranges overlap in grade, so the brand name alone tells you little; the line name — Classic, Koroneiki, Organic, Early Harvest, PDO Kalamata, Mountain Regions — is what identifies the product.
Does Minerva publish acidity or polyphenol figures?
No. We crawled all 371 URLs in the company's own sitemaps, including every product page in both languages, plus all 24 PDFs the site links to, and found no free acidity, peroxide value, K-coefficient, polyphenol figure or harvest date on any olive oil page. This is the norm across the category rather than unusual.
Is any Minerva olive oil PDO?
Yes — two lines carry PDO Kalamata, one under the Minerva brand and one under Horio. Kalamata is a registered Protected Designation of Origin (PDO-GR-0037, protected 13 June 1997) covering oil from the Messinia region of the south-western Peloponnese.
How does Sidr & Stone compare, and where do you buy each?
Minerva is a national Greek range sold through supermarkets and Greek grocers worldwide, strongest on availability and size choice. Sidr & Stone is a single-estate Moroccan oil sold direct in one 500ml format from one small harvest, with fulfilment in the UK, EU, and US. Different products for different jobs.
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
Minerva is a competent, long-established Greek producer that does several things well and one thing that trips people up. It names a cultivar where many national brands will not. It carries a genuine registered designation on two lines. Its organic lines say so. And its everyday blends are honestly named — the word "olive oil" rather than "extra virgin olive oil" on a Classic pack is the company telling you, correctly, what is inside.
What it does not give you is a number. Not acidity, not peroxide value, not a K-coefficient, not a polyphenol figure, not a harvest date. We checked properly before saying so, and the answer is the same one we get from most of the industry. If that frustrates you, the useful response is not to distrust one brand — it is to notice how rare published chemistry is across the whole aisle, and to ask for it. Our brand-agnostic guide to choosing a quality olive oil sets out what to look for in the meantime.
Our own answer is narrower and slower: one grove, one harvest, no blending, and no figure published that 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.
