ROI Olive Oil: The Ligurian Mill Behind the Taggiasca Crus
ROI olive oil is one of those searches that lands two different people on the same page. One of them wants return on investment. The other has picked up a slim bottle of Ligurian extra virgin and wants to know who made it. This article is for the second reader — and the answer is Olio Roi, a family mill in the village of Badalucco, in the Argentina Valley behind Sanremo, in the heart of Taggiasca country. What makes it worth a page of its own is not the region, which we have written about elsewhere, but something the company does that very few olive oil producers of any size bother with: it sells three separate single-grove oils and tells you, for each one, the altitude it grew at and the exact ripeness mix of the fruit that went into it.
For our own oil, see our cold-pressed organic Marrakech olive oil.
The Short Answer
- ROI is a mill, not a metric. Olio Roi S.r.l. is based at Via Argentina Sud 1, Badalucco, in the province of Imperia, Liguria, and registers itself as a Società Benefit — an Italian company form that writes public-benefit aims into the statute.
- The family dates itself to 1900. Its own account begins with Giuseppe, the great-grandfather known as "Pepin u Roi", who "built the first oil mill using the wood and stones of our valley", and runs to Paolo, who works in the mill with his father today.
- It farms 42 hectares with about 11,000 Taggiasca trees, sited between 60 and 500 metres above sea level, and states it has been organically certified — "Bio since 2002".
- Three of its PDO oils are single-grove crus. Riva Gianca comes from a grove at Sanremo at 60 metres, Morgaa from Montalto Ligure at 250 metres, and Gaaci from Badalucco at 500 metres — each with a published green-to-ripe split of the fruit at picking.
- It publishes no numeric chemistry. Across every oil page on its site there is no free acidity figure, no peroxide value, no K-coefficient and no polyphenol count. That is the category norm rather than a lapse; almost no producer at this scale publishes them.
- The denomination on the bottle is Riviera Ligure DOP with the Riviera dei Fiori mention. We cover what that designation actually requires in our article on Ligurian olive oil, so this piece stays on the producer.
- Sidr & Stone's own oil is a different proposition entirely — single-estate, rain-fed, organically grown and cold-pressed within hours of harvest near Marrakech, with fulfilment in the UK, EU, and US.
Who Olio Roi Actually Is
Olio Roi S.r.l. is a Ligurian olive oil company registered at Badalucco in the province of Imperia, and it constitutes itself as a Società Benefit — a form introduced in Italian law that obliges a company to pursue stated public-benefit purposes alongside profit. That is a legal status, not a marketing badge, and it is printed in the site's own footer alongside the VAT and company registration numbers.
The company's account of itself starts in 1900. "The history of the Roi family begins in 1900 when Giuseppe, the great-grandfather 'Pepin u Roi', built the first oil mill using the wood and stones of our valley," its about page says, adding that "more than 100 years have passed" and that the business now works with 42 countries. The present-day name in the copy is Paolo, described as spending his time in the family mill with his father.
The farming is specific. Olio Roi states it has expanded to 42 hectares carrying about 11,000 Taggiasca trees, sited between 60 and 500 metres above sea level and surrounded by Mediterranean scrub and chestnut woods. A section heading on that page reads "Bio since 2002".
Why the Name Confuses the Search
"Roi" is a Ligurian family name and, in this valley, a piece of local history — the great-grandfather's nickname, "Pepin u Roi", is where the brand comes from. In English-language search it collides head-on with ROI as an initialism for return on investment, which is why a query for the oil often returns spreadsheets.
The practical consequence is worth one line: if you are shopping, the term that disambiguates is Olio Roi, not ROI. The company writes it that way itself, and the bottles are labelled that way too.
The Three Crus: Grove, Altitude and Ripeness
This is the reason the producer is interesting. Rather than one house PDO oil, Olio Roi bottles three separate single-grove oils, each named for the grove and each carrying two pieces of information that almost never appear on a label: the altitude of the trees, and the proportion of green, part-ripe and black fruit at picking. Ripeness at harvest is the single biggest lever on how bitter and peppery an oil tastes, so publishing the split is a genuinely useful disclosure.
| Cru | Grove and place | Altitude stated | Ripeness at picking, as published |
|---|---|---|---|
| "Riva Gianca" (sea) | Olive grove at Sanremo, near the sea | 60 metres above sea level | 30% green, 50% not fully mature, 20% black |
| Organic "Morgaa" (hill) | Roi Morgaa grove, Montalto Ligure | 250 metres above sea level | 20% green, 50% not fully mature, 30% mature |
| Organic "Gaaci" (mountain) | Roi Gaaci grove, Badalucco | 500 metres above sea level | 40% green, 50% not fully mature, 10% black |
Read down the ripeness column and the pattern is legible: the mountain grove at 500 metres is picked greenest, the hill grove at 250 metres ripest. The 250 ml bottlings of all three carry a further line stating a limited production of about 2,000 bottles a year; the 500 ml versions of the same oils repeat the origin and ripeness text without it.
The house PDO oil, Carte Noire, is described instead as "a low-acidity oil obtained from a selection of the best Taggiasca olives" and "produced in limited series between 15,000 and 20,000 bottles". Note the wording: low acidity is asserted, not quantified. That distinction runs through the whole category, and it is the subject of the next section.
What Roi Publishes About Testing — and What It Does Not
Olio Roi keeps a dedicated "Certified quality" page, and on it the company states that "the chemical and multiresidual analyzes of raw materials and finished products are periodically carried out in samples by external laboratories certified by ACCREDIA" — the Italian national accreditation body. It also describes an HACCP regime, and states that its own professional tasters, working with an outside expert, taste and select all the oils.
For the designation itself, the company states that its olives come from selected suppliers certifying 100% Ligurian origin and Taggiasca cultivar, and that the Centro di Sperimentazione ed Assistenza Agricola — Made in Quality takes samples and performs the chemical analysis and organoleptic evaluation that certify the oil as PDO. It lists organic certification, Friend of the Earth, and a "Precision Agriculture" certification tied to the agronomy platform Elaisian, founded in 2016.
What none of that produces is a number. The analyses are described as happening; no result is published. That is worth stating plainly and without any implication of concealment, because it is the ordinary state of the category — and because we are in exactly the same position on the figure most readers care about.
| Figure | Olio Roi | Sidr & Stone |
|---|---|---|
| Free acidity (%) | Not published — described as "low acidity" | Not published |
| Peroxide value | Not published | Not published |
| K232 / K270 | Not published | Not published |
| Total polyphenols (mg/kg) | Not published | Not published |
| Harvest or crop year on the web page | Not published | Not published |
| Grove altitude | Published — 60 m, 250 m, 500 m by cru | Not published; grove is on the plains outside Marrakech |
| Ripeness split at picking | Published per cru | Not published; single harvest picked when the fruit is ready |
| Organic status | Certified organic — "Bio since 2002" | Organically grown; no formal certificate |
Two rows there go against us and we are not going to bury them. Olio Roi holds formal organic certification and we do not — ours is organically grown, without synthetic fertilisers, pesticides or herbicides, and we describe it that way rather than claim a certificate we have not been issued. And on grove-level detail, the cru pages tell a reader more than most producers do, including us.
One small correction, offered neutrally. The same page states that no food product can be sold in the United States without FDA approval. The Food and Drug Administration does not approve individual foods; food facilities register with the agency and are subject to inspection and to import controls. The company's underlying point — that it has been through a US regulatory process — is sound; the shorthand is not quite right.
The Mill: Three Ways of Crushing an Olive
The mill page is the most technically specific thing on the site. Olio Roi states that its current mill uses three different types of pressing — "the large granite millstones, a closed granite grinder and a steel knife crusher" — and that extraction runs on super presses or a three-phase decanter, with centrifugal separators finishing the job.
The line that matters most for quality is the next one: the processing is done "without heating the olive paste and without adding hot water". Adding warm water during malaxation raises yield and strips aroma and phenolics; saying plainly that you do not is a meaningful commitment. The company also notes that its mill is one of the teaching sites of the University of Gastronomic Sciences at Pollenzo.
Keeping three crushing systems is unusual and tells you something about intent. A knife crusher is fast and modern; granite millstones are slow, gentler on the paste and traditional. A mill that keeps both has decided the choice is worth making per batch rather than once, at purchase.
Three Objections Worth Taking Seriously
"A mild Ligurian oil is just a weak oil." It is a fair instinct and a wrong one here. The Riviera Ligure designation deliberately caps bitterness and pungency while setting acidity and peroxide limits stricter than the generic extra virgin standard — the full argument is in our piece on Ligurian olive oil. Gentle and tired are different states.
"They buy olives in, so is it really their oil?" Both things are true at once. Olio Roi farms 42 hectares of its own and states that its PDO olives come from selected suppliers certifying Ligurian origin and Taggiasca cultivar. That is a mill model rather than an estate model, and it is how most of Liguria works, given how small the terraced holdings are. It buys consistency and volume; it costs you the ability to trace a bottle to one field. The three crus are the part of the range where that trade is reversed.
"Without numbers, how do I judge it?" Honestly — you judge it on what is checkable. Origin, cultivar, denomination, grove, altitude, ripeness and crop year are all verifiable claims, and a producer publishing them is telling you more than one publishing an adjective. For what the numbers would add if they were there, see our explainer on olive oil polyphenols.
How to Read a Roi Bottle
| What you see | What it tells you | What it does not |
|---|---|---|
| "Riviera Ligure DOP — Riviera dei Fiori" | The registered designation and the exact geographic mention, verified against a specification | The age of your bottle, or any chemistry result |
| A cru name — Riva Gianca, Morgaa, Gaaci | One named grove, with a published altitude and ripeness split | Which season's pressing you are holding |
| "Cultivar Ogliarola-Taggiasca" | A blend of two named cultivars, stated as 100% Italian | Anything about proportions, or about Ligurian origin specifically |
| "Mosto" | An unfiltered-style pressing, described as first cold pressing | A denomination — the Mosto line is sold outside the PDO |
| The organic mark on Morgaa and Gaaci | Third-party certified organic production | Anything about flavour intensity or freshness |
One detail worth knowing. The company's quality page refers to the designation as "PDO Riviera Ligure (Riviera di Ponente)", an older regional shorthand, while the bottles themselves carry the exact registered mention, Riviera dei Fiori. Trust the bottle.

Why Sidr & Stone
We write about other producers because readers are researching them, and because the honest comparison usually teaches more than the sales page does. Olio Roi answers the question "how do you keep a valley's oil distinct at mill scale". Ours answers a narrower one: how short can the chain from tree to bottle be made.
- 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 — without synthetic fertilisers, pesticides or herbicides. We do not hold formal organic certification and do not claim it.
- Single harvest — a small, limited batch, picked only when the season says the fruit is ready, sometimes weeks later than neighbouring farms.
- Cold-pressed within hours of harvest — flavour, aroma and polyphenols preserved by pressing quickly and without added heat.
- Unfiltered extra virgin — minimally processed, so it may carry a little natural sediment, which is normal.
- 100% natural — one ingredient, olive oil, and nothing else.
- 500 ml dark glass with a gold label — protective packaging in a size built to be finished fresh.
- Halal certified, with 10% of profits given to charity.
- Fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is better than a good Ligurian cru — a fresh Gaaci or Morgaa is a fine oil and we would happily have one in the kitchen. What we will say is that ours is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, that we do not yet publish a polyphenol figure and will not imply one, and that a single-estate oil answers a different question from a mill's.
Frequently Asked Questions
What is ROI olive oil?
It is the extra virgin olive oil of Olio Roi, a family mill at Badalucco in the province of Imperia, Liguria. The range is built on the Taggiasca cultivar and includes three single-grove PDO oils as well as blended and flavoured lines.
Is ROI olive oil related to return on investment?
No. The overlap is an accident of initials. Roi is the family name behind the mill, taken from the great-grandfather's nickname "Pepin u Roi". Searching for "Olio Roi" rather than "ROI" will find the producer rather than the business metric.
Who owns Olio Roi?
It is a family business trading as Olio Roi S.r.l., constituted as a Società Benefit and based at Badalucco. The company traces itself to Giuseppe "Pepin u Roi" in 1900 and names Paolo as working in the mill with his father today.
What are the Roi crus?
Three single-grove PDO oils: Riva Gianca from a grove at Sanremo at 60 metres, Morgaa from Montalto Ligure at 250 metres, and Gaaci from Badalucco at 500 metres. Each page publishes the altitude and the green-to-ripe split of the fruit at harvest.
Does Olio Roi publish lab results?
Not as figures. The company states that chemical and multiresidual analyses are carried out periodically on samples by external laboratories accredited by ACCREDIA, and that a certification body performs the PDO chemical and sensory checks, but no acidity, peroxide or polyphenol values are printed on the site.
Is Olio Roi organic?
Parts of the range are. The company states organic certification and heads its farming page "Bio since 2002", and the Morgaa and Gaaci crus are sold as organic PDO oils. Other lines in the range are not marketed as organic.
Where can you buy ROI olive oil?
Olio Roi sells from its own online shop and from stores attached to the mill at Badalucco, and it states that it trades into 42 countries. Italian delicatessens and specialist oil retailers are the usual route elsewhere. Check the crop year on the bottle, which Riviera Ligure DOP labels are required to carry.
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
Most producer pages are a mood. This one is a set of claims you could go and check: a village, a company form, a year, a hectarage, a tree count, an altitude band, three named groves, a ripeness split for each, and a description of the crushing equipment specific enough to argue with.
What is missing is the chemistry, and it is missing everywhere in this category — which is why the fair way to read it is as a norm rather than a failing, and why we have said openly in the table above that our own polyphenol row reads "Not published" too. Until a producer prints a number, the checkable things are the ones to buy on.
So: if you want a Ligurian oil with a traceable field behind it, one of the three crus is the part of the Roi range that gives you most for your attention. If you want a gentle house oil, Carte Noire is what the mill is known for. Either way, look for the crop year before you look at anything else.
Our cold-pressed organic Marrakech olive oil — single-estate, rain-fed, organically grown and pressed within hours of harvest — is available to pre-order as a limited first harvest. Estimated shipping from November 2026. Fulfilment in the UK, EU, and US.
