Bertolli Olive Oil: Heritage, Sourcing, and How to Choose Well
By Yusuf Elsayed, Founder of Sidr & Stone · Last updated 4 June 2026Share
If you are looking into Bertolli olive oil, you are looking at one of the most recognised names in the category — a brand that has been selling olive oil since 1865 and was, for years, the world's best-selling olive oil. That history is real, and it is worth understanding before you decide whether a bottle belongs in your kitchen. This article looks at Bertolli honestly: who the brand is, where its oil actually comes from, what the "extra virgin" grade does and does not guarantee, and how to judge any olive oil — Bertolli's or anyone else's — on the things that genuinely matter.
For our own oil, see our cold-pressed organic Marrakech olive oil.
The Short Answer
- Bertolli is a genuine heritage brand, founded in Lucca, Tuscany, in 1865. It became the global market leader in olive oil and is widely available and accessible — both real strengths.
- The brand is no longer Italian-owned. Its olive oil business has belonged to the Spanish group Deoleo since 2008; the wider Bertolli trademark is held by Japan's Mizkan.
- Bertolli extra virgin olive oil is a blend drawn from across the Mediterranean — typically Spain, Tunisia, Greece, and a smaller share from Italy — rather than oil from a single estate or single country.
- "Extra virgin" is a real, regulated grade, but it is a category that has been tested and found inconsistent. A 2010 University of California, Davis study flagged several major supermarket brands, Bertolli among them, as not meeting the extra virgin standard in the samples tested.
- The most useful question is not "which famous name?" but "can I trace this oil, and how fresh is it?" Single-origin traceability and time-from-harvest matter more than the label.
- Sidr & Stone takes the opposite approach to a large blend: a single-estate, rain-fed, organically grown oil from one grove near Marrakech, cold-pressed within hours of harvest and unfiltered.
Who Bertolli Is: A 160-Year-Old Italian Name
Bertolli began in 1865 in Lucca, Tuscany, where Francesco Bertolli and his wife Caterina ran a small shop. It grew into an international business and, for a long stretch of the twentieth and early twenty-first centuries, was the best-selling olive oil brand in the world. That is not marketing gloss — it is a genuine commercial achievement, and it is the main reason the name carries the trust it does today.
It is worth being clear about what Bertolli has become, though, because the branding still leans heavily on its Tuscan origins. The olive oil business was sold by Unilever to the Spanish group Grupo SOS — now Deoleo — in 2008. Deoleo is one of the largest olive oil companies in the world and also owns names such as Carapelli and Carbonell. The broader Bertolli trademark, covering products like pasta sauces, sits with the Japanese group Mizkan. So the "Italian family" story is a heritage story, not a description of who makes and owns the oil now.
None of this makes Bertolli a poor product. It makes it a large, professionally run, mass-market brand — which comes with genuine advantages (consistency, availability, price, quality-control systems) and genuine trade-offs (scale, blending, distance from the grove). The point is simply to see it as it is.

Where Bertolli's Olive Oil Actually Comes From
This is the part most shoppers do not expect. Despite the Tuscan heritage on the label, Bertolli's olive oil is a Mediterranean blend. Published sourcing breakdowns describe the majority of the olives coming from Spain — by some accounts up to around 60% — with sizeable shares from Tunisia and Greece, and often only a small percentage from Italy itself. The oil is blended to a consistent house style and bottled at scale.
Blending across countries is completely standard practice for large commodity olive oil, and it is not dishonest in itself — the labels are generally explicit that the oil is a blend of oils from more than one country. But it does mean that "Bertolli" describes a recipe and a brand, not a place. You are not buying the output of one grove or one harvest; you are buying a blend assembled to taste the same bottle after bottle, year after year.
Whether that matters depends on what you want. If you want a dependable, everyday cooking oil that tastes consistent and is easy to find, a large blend does that job well. If you want to know exactly where your oil grew, who tended the trees, and how soon after picking it was pressed, a multi-country blend cannot answer those questions — by design.

What "Extra Virgin" Means — and Why It Has Been Tested
"Extra virgin" is a regulated grade, not a marketing word. To qualify, an oil must be produced by mechanical means only, have a free acidity of no more than 0.8%, and pass a sensory panel with no detectable defects. Bertolli states a maximum acidity of 0.3% for its extra virgin oil, which is well inside the legal limit and a reasonable figure to publish.
The honest complication is that extra virgin, as a category, has not always lived up to its own grade on the shelf. In 2010, a study by the University of California, Davis tested a range of imported "extra virgin" olive oils sold in the United States and found that a number of major brands — Bertolli among them — failed to meet the extra virgin standard in the samples tested, usually on sensory grounds. In 2018, Deoleo agreed a multi-million-dollar settlement in the United States to resolve a class action over how some of its olive oil had been represented. These are matters of public record, and we mention them not to single Bertolli out — several household names appeared in the same findings — but because they make a wider point: a famous label is not, on its own, a guarantee of what is in the bottle.
That is the real takeaway. The grade matters, the acidity figure matters, but the thing that protects you most is verification you can actually trace — origin, harvest, and pressing — rather than a category name that has, across the industry, proven variable.

Single-Estate vs a Mediterranean Blend: The Real Difference
This is where Bertolli and an oil like ours differ most, and it is a difference of model rather than a matter of one brand being "good" and another "bad". Bertolli is a large multi-country blend built for consistency and scale. Sidr & Stone's olive oil is the opposite: a single-estate oil from one family-owned grove on the plains outside Marrakech, Morocco — rain-fed, organically grown without synthetic inputs, harvested in a single small batch, and cold-pressed within hours of picking. It is unfiltered, which means it may carry a little natural sediment, and it is bottled in dark glass to protect it from light.
The practical consequences are real. A single estate means one origin you can name, not a recipe spanning several countries. Cold-pressing within hours of harvest protects the flavour and the polyphenols that fresh oil is prized for. A single annual harvest means the oil is a product of one season, not a year-round blend — when it is gone, it is gone until the next pressing. None of this makes a large blend wrong for everyday cooking; it makes a single-estate oil a different proposition for people who care about traceability and freshness.

Why Sidr & Stone
We write about brands like Bertolli not to talk them down — Bertolli has earned its place — but because the questions a shopper asks about a famous blend are the same questions worth asking about any oil, including ours. Here is what our olive oil is, stated plainly:
- Single-estate — one family-owned grove near Marrakech, Morocco, with no blending across origins.
- Rain-fed — no irrigation; the trees take what the season gives them.
- Organically grown — without synthetic fertilisers, pesticides, or herbicides.
- Single harvest — a small, limited batch; once a season's pressing is gone, it is gone until next year.
- Cold-pressed within hours of harvest — flavour, aroma, and polyphenols preserved.
- Unfiltered extra virgin — minimally processed; natural sediment is normal and expected.
- 100% natural — a single ingredient, olive oil, with nothing added.
- Dark glass with a gold label — protective packaging against light.
- Halal certified, with 10% of profits given to charity.
- 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 this article warns against. 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
Is Bertolli olive oil good?
For an accessible, consistent, everyday olive oil it is a reasonable choice, and the brand publishes a sensible acidity figure. Its main limitation is that it is a large multi-country blend, so it cannot offer single-origin traceability or the freshness of a small single-harvest oil.
Where is Bertolli olive oil from?
Despite its Tuscan heritage, Bertolli's extra virgin oil is a Mediterranean blend, with the majority of olives typically from Spain and further shares from Tunisia, Greece, and a smaller portion from Italy. It is a brand recipe rather than a single place.
Is Bertolli still an Italian company?
Not in ownership. The olive oil business has belonged to the Spanish group Deoleo since 2008, and the wider Bertolli trademark is held by Japan's Mizkan. The Italian roots are a genuine heritage, but the company behind the oil today is not Italian-owned.
What does "extra virgin" actually guarantee?
Extra virgin is a regulated grade requiring mechanical extraction, free acidity of no more than 0.8%, and no sensory defects. It is meaningful, but independent testing has shown the category can be inconsistent on the shelf — which is why traceable origin and freshness matter alongside the grade.
Why was Bertolli involved in olive oil testing controversies?
A 2010 University of California, Davis study found several major imported brands, including Bertolli, did not meet the extra virgin standard in the samples tested, and in 2018 parent company Deoleo settled a related US class action. These are matters of public record and reflect a wider, category-wide quality-variability issue rather than a problem unique to one name.
How is a single-estate olive oil different from Bertolli?
A single-estate oil comes from one named grove and usually one harvest, so you can trace exactly where and when it was made. A large blend like Bertolli is built for year-round consistency across multiple countries, which trades that traceability for scale and availability.
Where can I buy Sidr & Stone olive oil?
Our single-estate Marrakech olive oil is available to pre-order now from our product page, as a limited first harvest, 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
Bertolli is a famous name for understandable reasons: a long heritage, real scale, broad availability, and a consistent everyday product. If that is what you want, it does the job. The honest qualification is that a famous label is a brand, not a guarantee — and that the things which most reliably tell you about an olive oil are the ones a large multi-country blend cannot show you: a single named origin, a recent harvest, and an oil pressed soon after picking.
That is the gap we set out to fill. Rather than assemble a blend for year-round consistency, we make one oil, from one grove, in one season, and we are plain about exactly what it is. You do not have to take a label's word for it; you can read where it grew and how it was made.
Our cold-pressed organic Marrakech olive oil — single-estate, rain-fed, organically grown, and cold-pressed within hours of harvest — is available to pre-order now as a limited first harvest, with fulfilment in the UK, EU, and US.
