Olio Santo Olive Oil: The Brand, the Bottle and the Calabrian Original
Search for olio santo olive oil and you will get two completely different products wearing the same name. One is a Californian extra virgin olive oil made by Stonehouse Olive Oil, best known outside the trade because Ina Garten has cooked with it for years. The other is olio santo in its original Italian sense — a Calabrian chilli-infused oil, made at home every autumn from fresh peperoncini and extra virgin oil, and used as a condiment rather than a cooking fat. Neither is a mistake. They simply share a name, and which one you want changes what you should be looking at on the label. This article covers both, using what each source actually publishes.
For our own oil, see our cold-pressed organic Marrakech olive oil — a single-estate Moroccan extra virgin oil, unfiltered and unblended.
The Short Answer
- Olio Santo is a Californian extra virgin olive oil brand made by Stonehouse Olive Oil. Stonehouse's own product page describes it as the oil that "started the California extra virgin olive oil movement in 1996".
- Stonehouse states on that page that Olio Santo "has been Ina Garten's and Williams Sonoma's EVOO of choice for over 25 years". That endorsement is the reason the name trends.
- Stonehouse publishes a harvest date on the bottle and on every product page — the Olio Santo page showed a harvest of October 2025 to January 2026 when we checked on 21 August 2026. That is a genuine transparency practice and we credit it plainly.
- Stonehouse's About page states that its oils are "certified Extra Virgin by Modern Olives, a third party lab", and that its groves are "in transition to become certified Organic". Both are honest, checkable statements.
- Olio Santo is filtered, by design. Stonehouse explains why on the product page. Ours is unfiltered. Both positions are defensible and we set out the trade-off below rather than pretending one is simply right.
- Separately, olio santo is the traditional Calabrian name for hot chilli oil — literally "holy oil". If that is what you meant, you want a recipe and a food-safety note, not a grade standard.
- Sidr & Stone's olive oil is single-estate, rain-fed, organically grown and cold-pressed within hours of harvest near Marrakech. We do not yet publish a laboratory panel for it, and we say so.
Which Olio Santo Do You Mean?
The quickest way to sort this out is to notice what the bottle is for. If it is a 500ml or larger bottle of pale-labelled Californian extra virgin oil intended for cooking, dressing and finishing, you mean the brand. If it is a small bottle or jar of oil with visible chilli flakes in it, meant to be shaken over pizza, pasta or soup a few drops at a time, you mean the Calabrian condiment.
| Olio Santo (the brand) | Olio santo (the Calabrian condiment) | |
|---|---|---|
| What it is | Extra virgin olive oil | Extra virgin olive oil infused with hot chilli |
| Where it comes from | California, made by Stonehouse Olive Oil | Calabria, southern Italy — usually homemade |
| What it is for | Everyday cooking, roasting, dressing, finishing | A finishing condiment, used sparingly |
| What to check | Harvest date, grade, acidity, filtration | Whether the chilli was dried or salted before it met the oil |
| Typical format | Bottles and bulk tins | Small jars and shaker bottles |
Olio Santo the Brand: What Stonehouse Actually Publishes
We read Stonehouse's own pages rather than reviews, and there is more on them than most brand pages carry.
The Olio Santo product page describes the oil as "smooth, creamy and mild, with just a hint of a piquancy on the finish", and positions it as "an excellent all-purpose EVOO, perfect for cooking, sauces, roasting, dressing greens and vegetables, for finishing, or enjoyed simply with fresh bread". It states that the olives are "grown herbicide and pesticide free, cold-pressed, and filtered, to prolong freshness". It gives a harvest window for the current bottling, and Stonehouse's FAQ confirms the practice generally: "We harvest October-January each year, and you'll see a harvest date sticker on the back of each bottle and on every product's page when you order."
The About page adds that Stonehouse has operated since 1996, is "proudly women-owned and operated", that many of its groves are "in transition to become certified Organic", and that its oils "are certified Extra Virgin by Modern Olives, a third party lab". It lists awards including gold and silver at the 2024 New York International Olive Oil Competition and medals at the Los Angeles County Fair. Its FAQ also references third-party lab testing of its oils over time and cites a 0.3% acidity figure achieved through improvements in milling — comfortably inside the 0.8% ceiling that defines extra virgin.
| What a buyer wants to know | Published by Stonehouse for Olio Santo? | Detail as read on 21 August 2026 |
|---|---|---|
| Harvest date | Yes | October 2025 – January 2026, shown on the product page and stickered on the bottle |
| Grade | Yes | Extra virgin, certified by Modern Olives, a third-party laboratory |
| Free acidity | Referenced in the FAQ | 0.3% cited as the level modern milling delivers, against an 0.8% EVOO ceiling |
| Filtration | Yes | Filtered, with a stated reason: to remove matter that degrades oil over time |
| Growing practice | Yes | Herbicide and pesticide free; groves in transition to organic certification |
| Olive variety | Not found | No cultivar breakdown located on the product page or FAQ |
| Polyphenol figure in mg/kg | Not found | The page says the oil is "full of polyphenols"; we found no numeric result published |
Two of those rows deserve a fair reading. A named third-party laboratory and a harvest date on the bottle put Stonehouse ahead of most of the shelf — we are not going to downplay that, and a reader comparing brands should weight it. The two "not found" rows are not accusations. Most olive oil brands publish neither a cultivar list nor a polyphenol number, and the absence is a category norm rather than a Stonehouse failing. It is simply the information that would let you compare oils on chemistry instead of on description. For how to read that information when it is available, see our guide to high phenolic olive oil.
Filtered or Unfiltered: The Honest Trade-Off
Olio Santo is filtered and says so, with a reason: filtering removes the fine particulate and residual water that slowly degrade an oil in the bottle. Our own oil is unfiltered. Both choices are legitimate, and anyone telling you otherwise is selling something.
| Filtered (Olio Santo's choice) | Unfiltered (ours) | |
|---|---|---|
| Appearance | Bright and clear | Hazy, with natural sediment that settles |
| Main argument for it | Longer stability in the bottle; less matter to degrade | Nothing removed after pressing; more of the fruit's own solids retained |
| Main argument against it | A processing step between press and bottle | Sediment can shorten practical shelf life if the bottle is kept warm |
| Who it suits | Buyers holding a large format over months | Buyers who will finish a smaller bottle within a season |
The sediment in an unfiltered oil is normal and is not a fault. It is fruit solids, and it settles. If you have not met it before, our piece on unfiltered versus filtered olive oil goes through it properly. The practical rule for either style is the same: keep the bottle dark, keep it cool, and use it while it is young. Harvest date beats every other date on a bottle, which is why we credit Stonehouse for printing one — see our piece on fresh pressed olive oil for why.
Olio Santo the Calabrian Condiment
In Calabria, olio santo means hot chilli oil. The name translates as "holy oil", and it is a household preserve rather than a commercial grade. Italian food publications set out a consistent traditional method: fresh Calabrian chillies are sliced thinly — seeds traditionally left in — then salted heavily and left overnight so they give up their water, before being covered with extra virgin olive oil and sealed in a jar.
That salting step is not decoration. Water is what turns an oil infusion from a preserve into a risk, because low-acid produce submerged in oil is the classic environment for Clostridium botulinum. Traditional practice drives the moisture out first. Modern home cooks are usually better served by dried chilli, which sidesteps the problem entirely. We cover the safe methods in our guides to chilli olive oil and infused olive oil, including the storage rules for anything infused with fresh ingredients.
One point of etiquette worth knowing: an olio santo is meant to be a light touch on a finished dish, not a cooking medium. A few drops on a pizza or a bowl of beans. It is also, by construction, an infused product — so the oil underneath matters less than it would in a finishing oil you taste on its own.
The Objections Worth Taking Seriously
"You are only writing this to sell your own oil." We do sell olive oil, and we are not going to pretend the article has no commercial purpose. What we can do is keep every claim about Olio Santo traceable to Stonehouse's own pages, credit what they do well, and not invent faults. If you finish this page and buy Olio Santo because a harvest-dated Californian oil with third-party certification suits you better, that is a reasonable decision and we have not misled you into it.
"A celebrity endorsement isn't evidence of quality." True, and worth saying. Ina Garten's long use of Olio Santo tells you it is a reliable all-purpose oil that a very experienced cook enjoys. It tells you nothing about acidity, polyphenols or harvest freshness. The harvest sticker and the third-party certification tell you those things, and they are the parts to weight.
"Californian oil can't compete with Mediterranean oil." This one does not survive contact with the evidence. California has produced serious extra virgin oil for three decades, and Stonehouse's competition results are a fair reflection of that. Geography is a weaker signal than harvest date, storage and grade. We say the same about Moroccan oil, which is our own origin — see California olive oil brands for a wider look at the region.
Why Sidr & Stone
We write brand articles like this one because the alternative — a page of scraped marketing copy — is not useful to anyone. Where a brand publishes something we do not, we say so. Stonehouse prints a harvest date on the bottle and names its third-party laboratory; those are two things we admire and two things we intend to match.
Our own oil is straightforward:
- 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. We do not hold a formal organic certificate and we do not claim one.
- Single harvest — a small batch, once a season. Picked when the season says the fruit is ready, which can be weeks later than neighbouring farms.
- Cold-pressed within hours of harvest — flavour, aroma and polyphenols preserved by keeping the gap between picking and pressing short.
- Unfiltered extra virgin — minimally processed, and it may show natural sediment.
- 100% natural — one ingredient, and nothing added.
- Dark glass with a gold label — protective packaging against light.
- Halal certified, with 10% of profits to charity as a brand-wide commitment, and 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 size of the season's limited batch. Our laboratory panel is not published yet. When it is, it will sit here with a number on it, in the same way Stonehouse names its laboratory.
Frequently Asked Questions
What is Olio Santo olive oil?
Olio Santo is a Californian extra virgin olive oil made by Stonehouse Olive Oil, which describes it as the oil that started the California extra virgin movement in 1996. Separately, olio santo is the Calabrian name for chilli-infused olive oil.
Who makes Olio Santo?
Stonehouse Olive Oil, a Californian producer trading since 1996. Its About page states the company is women-owned and operated and that its oils are certified extra virgin by Modern Olives, a third-party laboratory.
Is Olio Santo the olive oil Ina Garten uses?
Stonehouse's own product page states that Olio Santo "has been Ina Garten's and Williams Sonoma's EVOO of choice for over 25 years". That is the brand's claim on its own site, and it is the main reason the name is searched.
Is Olio Santo filtered or unfiltered?
Filtered. Stonehouse states this openly on the product page and gives its reasoning — that filtering removes particulate matter which degrades oil over time. Our own oil is unfiltered, which is a different and equally defensible choice.
Does Olio Santo publish a polyphenol figure?
We did not find one. The product page describes the oil as full of polyphenols but gives no milligrams per kilogram. Most olive oil brands publish no polyphenol number, so this is a category norm rather than a criticism of Stonehouse.
What does olio santo mean in Italian?
Literally "holy oil". In Calabria it refers to a homemade chilli condiment: fresh hot peperoncini sliced thin, salted overnight to draw out water, then covered with extra virgin olive oil and sealed.
How does Sidr & Stone's olive oil compare?
Ours is a single-estate Moroccan extra virgin oil from one family-owned grove near Marrakech — rain-fed, organically grown, cold-pressed within hours of harvest and unfiltered. Stonehouse publishes a harvest date and names its laboratory; we do not yet publish a laboratory panel.
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
The two olio santos have almost nothing in common except a name and a base ingredient, and knowing which one you are after solves most of the confusion in about ten seconds. If it is the Californian brand, you are buying a mild, all-purpose extra virgin oil from a producer that prints a harvest date, names a third-party laboratory and has been at it since 1996. That is a solid set of credentials and we have no interest in talking you out of it.
If it is the Calabrian condiment, you are not buying a grade at all — you are making or buying a preserve, and the questions that matter are about how the chilli was dried and how the jar is stored.
What links both, and what links every olive oil article we write, is that the useful information is nearly always the specific kind: a date, a grade, a number, a named laboratory. Description is easy. Specifics are the part that costs something to produce, which is exactly why they are worth looking for. Our guide to choosing a quality olive oil is the practical version of that argument.
Our cold-pressed organic Marrakech olive oil — single-estate, rain-fed, organically grown and unfiltered — is available to pre-order. First harvest, estimated shipping from November 2026. Fulfilment in the UK, EU, and US.
