Taggiasca Olives: The Cultivar, the PGI, and What Is in the Jar
Taggiasca olives are the small dark fruit of Liguria, and the word on the jar tells you less than most buyers assume. Taggiasca is a cultivar name, and a cultivar can be grown anywhere. What changed in 2023 is that the phrase Olive taggiasche liguri became a registered protected geographical indication with a published specification behind it — one that fixes a minimum size, a sweetness median, a bitterness ceiling, a brine strength, and even how easily the flesh has to come away from the stone. This article reads that specification, sets out what a taggiasca olive actually is, and explains what to look for on a jar.

The Short Answer
- Taggiasca is a Ligurian olive cultivar with an unusual dual use: the same fruit supplies both the table olives sold in brine and the region's extra virgin oil.
- Olive taggiasche liguri is a protected geographical indication, file number PGI-IT-03011, protected from 5 October 2023 and registered by the act published in Official Journal L, 2025/1995 of 2 October 2025.
- The designation covers five things, not one: olives in brine, dried pitted olives, pitted olives in brine, pitted olives in extra virgin olive oil, and olive paste or pâté.
- The specification publishes checkable numbers — a minimum size of 10 mm, a sweetness median of at least 2.0, a bitterness median no higher than 3.0, and an ease-of-pitting median of at least 8.0 for whole olives.
- Deacidification with alkaline chemical agents is prohibited. These are brine-fermented olives: 5% to 15% sodium chloride, and at least 45 days in the brine before anything else happens to them.
- The protected name is the full Italian phrase, not the single word. The specification itself distinguishes Ligurian taggiasche from taggiasche grown elsewhere, and says the Ligurian fruit is the sweeter of the two.
- Sidr & Stone does not sell table olives. Our one olive product is a single-estate, rain-fed, organically grown oil from a family grove on the plains outside Marrakech.
What a Taggiasca Olive Actually Is
A taggiasca olive is small — the specification sets its minimum size at 10 mm — oval and slightly elongated, and it ripens through a range of colours the text describes as green to purplish green, typically iridescent, then dark brown or black. The flesh is firm rather than meaty, the aroma is fruity, and the taste is slightly acid and well balanced with a slight bitter note. What people usually notice first is that the stone comes away almost without effort.
The variety takes its name from Taggia, the town in the province of Imperia where, the specification records, Benedictine monks planted the first trees in the tenth century. A small discrepancy is worth flagging for anyone who reads both documents: this table-olive specification dates that planting to the tenth century, while the Riviera Ligure oil designation's specification — which we quote in our article on Ligurian olive oil — puts it in the ninth. We cannot settle that; we simply report what each text says.
The dual use is the genuinely interesting part. Most famous cultivars lean heavily one way, grown either for the table or for oil. Taggiasca does both, and the specification names that dual use as one of the reasons the variety spread across a region with very little flat land. For the botany underneath all of this, our guide to the olive tree covers what a cultivar is and how it differs from a botanical variety.
Olive Taggiasche Liguri: The Protected Name and the Five Things It Covers
The name entered the EU register under file number PGI-IT-03011, as a protected geographical indication rather than a protected designation of origin, in product category 147 — the register's class for fruit, vegetables and cereals, fresh or processed. Protection runs from 5 October 2023, and the registering act appeared in Official Journal L, 2025/1995 on 2 October 2025. The production area is the entire administrative territory of the Liguria Region, and the olives must be packed inside it.
Most writing about this treats the designation as though it protects one product. It protects five.
| Product type, as the specification names it | What it is | What the label has to add |
|---|---|---|
| In brine | Whole olives, the standard form, matured in salt solution | The words “in brine” |
| Dried pitted | Olives pitted after maturation, then centrifuged to dry | The words “dried pitted” |
| Pitted, in brine | Pitted olives kept in the preserving liquid | The words “pitted, in brine” |
| Pitted, in extra virgin olive oil | Pitted olives with extra virgin olive oil added at 30% to 40% of the weight of the olives | The product type, plus the percentage of olive oil in the net weight |
| Paste or pâté | Flesh ground to a fine, creamy, spreadable paste, then packed and pasteurised | The words “paste” or “pâté” |
Retail packs run from 40 g to 5.0 kg, and where the contents sit in a preserving liquid that figure is the drained weight rather than the weight of everything in the jar. Larger packs without a weight limit are permitted for onward processing but may not be sold to a final consumer. The specification's stated reasons for requiring packing inside Liguria are traceability, the product's microbiological fragility, tradition and consumer transparency — and a reader is entitled to think the first of those does most of the work.
The Numbers the Specification Publishes
Under the PGI specification, whole Olive taggiasche liguri in brine must reach a minimum size of 10 mm, a sweetness median of at least 2.0, a bitterness median no higher than 3.0, and an ease-of-pitting median of at least 8.0. Those sensory attributes are assessed using the International Olive Council's method for the sensory analysis of table olives.
That method is IOC document COI/OT/MO No 1/Rev. 3 of June 2021 — the table-olive instrument, which is a different document from the trade standard used to grade oil. Set out together, the requirements look like this.
| Parameter | What the specification requires | What it is doing |
|---|---|---|
| Minimum size | 10 mm | Sorting removes drupes too small to carry the name |
| Sweetness median | At least 2.0 | A floor — sweetness is the character the designation is built on |
| Bitterness median | No higher than 3.0 | A ceiling — an aggressively bitter taggiasca is out of specification |
| Ease of pitting, whole olives | Median at least 8.0 | The flesh has to part cleanly from the stone |
| Brine strength | 5% to 15% sodium chloride, inclusive | The fermentation medium |
| Minimum time in brine | 45 days | Maturation, before pitting or grinding is permitted |
| Added oil, pitted olives in extra virgin olive oil | 30% to 40% of the weight of the olives | And the percentage must be declared on the label |
| Retail net weight | 40 g to 5.0 kg, drained where in liquid | Fixes what you are actually buying |
| Alkaline deacidification | Prohibited | No chemical debittering; the bitterness has to come out in brine |
The last row is the one worth dwelling on. A great deal of the world's table-olive production is debittered quickly using a dilute alkaline solution, which is a legitimate and long-established process. This designation forbids it outright, which is why the minimum is forty-five days rather than a few. For the international rules on what any tub of olives has to declare — type, trade preparation, style and size — our guide to Kalamata olives works through the Codex standard in full, and we will not repeat it here.
Why They Taste Sweet — and What the Specification Does Not Claim
This designation is unusual in resting explicitly on reputation rather than on a claim that the place causes the character. Even so, the specification offers an explanation, and a specific one. Liguria's growing season — hot dry summers, no extreme temperature changes, constant breezes — produces slow and homogeneous ripening, which lets growers stagger the harvest by altitude and take advantage of a longer window in which sugar accumulates in the fruit. The text cites survey work by CeRSAA in 2021, and by CeRSAA with LABCAM in 2024, showing higher average carbohydrates in Ligurian taggiasche than in other varieties.
It also makes a statement most marketing would bury. Because of Liguria's position close to the 45th parallel — a lower average temperature, no extreme diurnal differences, less intense daylight than olive regions further south — the polyphenol content is, in the specification's own words, statistically less than for other olives, and shows up as the slight bitterness that offsets the sweetness. That is a compositional observation about a cured table olive, published in that olive's own specification. It is not a health claim, and it has nothing to do with the separate authorised EU claim about olive oil polyphenols, which is a dietary claim about oil expressed as hydroxytyrosol and its derivatives per 20 g. Our piece on Italian olives sets out why those two numbers must not be run together.
The most useful line for a buyer is the comparison the specification draws itself: the sweetness is higher than that of other olives, whether from different cultivars or from taggiasche olives not produced in Liguria. The designation exists precisely because the cultivar is grown outside its home region, and the register's answer is that the Ligurian fruit is a different eating experience — not that it comes from a better plant.
Taggiasca and Cailletier: A Question We Could Not Settle
Search for taggiasca and you will quickly meet the claim that it is the same cultivar as the French Cailletier — the olive of the Nice hinterland, and the one that goes into salade niçoise. It is repeated widely enough to look settled. We could not verify it to a standard we would be willing to print.
Here is what we could verify. France holds a protected designation of origin, Olive de Nice, file number PDO-FR-0333, in the same product category 147 and protected from 29 October 2003. Its single document states that the designation covers table olives and olive paste obtained exclusively from the Cailletier variety, and it sets its own size rule: 100 g of the olives must comprise not fewer than 40 fruit and not more than 70. The Italian specification names the taggiasca variety. Neither text mentions the other's variety name, and the one peer-reviewed paper we could reach that names both — Breton and colleagues, writing in Plants in 2021 — lists Taggiasca and Cailletier as separate entries in tables of pollination crosses rather than as synonyms of one another. The claim may well be true. The documents we can check do not establish it.
| What the register records | Olive taggiasche liguri | Olive de Nice |
|---|---|---|
| File number | PGI-IT-03011 | PDO-FR-0333 |
| Type | Protected geographical indication | Protected designation of origin |
| Register category | 147 — fruit, vegetables and cereals | 147 — fruit, vegetables and cereals |
| Protected from | 5 October 2023 | 29 October 2003 |
| Variety the specification names | taggiasca | Cailletier, exclusively |
| A published size rule | Minimum size 10 mm | Not fewer than 40 and not more than 70 fruit per 100 g |
How to Buy Taggiasca Olives Well
Six checks do almost all of the work, and none of them require a trained palate.
- The full protected name. Olive taggiasche liguri is the registered phrase; taggiasca on its own is a cultivar name and guarantees nothing about where the fruit grew.
- The IGP or PGI wording and the EU symbol. The specification requires both, alongside the designation's own logo, on every pack that uses the name.
- The product type. In brine, dried pitted, pitted in brine, pitted in extra virgin olive oil, or paste — it is mandatory on the label, and it changes what you are eating.
- The oil percentage on jars packed in oil. Required, and it tells you how much of the jar is olive and how much is oil.
- The drained weight. Where the olives sit in liquid, the declared net weight is the drained figure, so two jars of the same volume are not the same purchase.
- A place more specific than Italy. A country of packing is not an origin, and the designation's whole point is that Liguria is the relevant unit.
Storage is unglamorous: keep an opened jar cold, keep the olives under their liquid, and finish it within a reasonable time. If you are buying the oil rather than the fruit, our guide to choosing a quality olive oil is the companion piece to this one.
The Objections Worth Taking Seriously
A PGI resting on reputation is weaker than a PDO resting on terroir. That is a fair reading of the hierarchy, and the specification says plainly that recognition is based on reputation. What the designation changes is not the quality of the olive but the quantity of checkable information attached to it: the medians, the brine strength, the forty-five days, the size floor. None of those would be public if nobody had been made to write them down.
Requiring the packing to happen in Liguria is protectionism. Possibly. The specification gives four reasons, and only the first — avoiding olives of a different provenance being mixed in — is squarely a traceability argument. The others are about perishability, tradition and consumer transparency, and reasonable people will weigh them differently.
And one refusal. A good deal of what gets written around this subject asks whether taggiasca olives are healthier than other olives. We are not going to answer that. No standard ranks olives against one another on that basis, the specification's remark about polyphenol content is a compositional observation rather than a health claim, and olives are food.
Why Sidr & Stone
We should be straightforward about our standing here. Sidr & Stone sells no table olives, and nothing in this article routes towards a purchase of any. What connects it to us is the habit of preferring a document to an adjective. We hold our own oil to the same test, and where we cannot yet produce the document, we say so.
- 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 a formal organic certificate and we do not claim one.
- Single harvest — a small batch pressed once a season, picked when the fruit is ready rather than when the calendar says so.
- Cold-pressed within hours of harvest — which is what keeps the flavour, aroma and polyphenols intact.
- 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 — packaging that protects the oil from light.
- Halal certified, with 10% of profits given to charity as a brand-wide commitment.
- Fulfilment in the UK, EU, and US.
And the asymmetry, said out loud: the Ligurian designation publishes medians we do not. We have not yet had a laboratory panel done, so we publish no polyphenol figure, no acidity result and no peroxide value for our own oil. We will not tell you Sidr & Stone is the best olive oil — that is exactly the sort of unfalsifiable claim this article has spent its length picking apart. What we will say is that ours is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, and that we would rather name the gap than dress it up.
Frequently Asked Questions
What are taggiasca olives?
They are small oval olives of the taggiasca variety, grown in Liguria in north-west Italy and cured in brine. They are sweet rather than sharp, with a slight bitter note, firm flesh and a stone that separates easily. Since 2023 the name Olive taggiasche liguri has been a protected geographical indication.
What do taggiasca olives taste like?
Sweet, well balanced and slightly acid, with a fruity aroma and only a slight bitterness. The specification writes that character into the rules: a sweetness median of at least 2.0 and a bitterness median no higher than 3.0, assessed by the International Olive Council's table-olive sensory method.
How can you tell if taggiasca olives are the genuine Ligurian product?
Look for the full registered phrase Olive taggiasche liguri, the words Indicazione Geografica Protetta or IGP, the EU protected geographical indication symbol, and the designation's own logo. The single word taggiasca is a cultivar name and can lawfully be used for fruit grown anywhere.
Are taggiasca and Cailletier the same olive?
They are often said to be, and we could not confirm it. The French Olive de Nice PDO names Cailletier exclusively; the Ligurian PGI names taggiasca; neither text refers to the other's variety, and the peer-reviewed work we could reach treats the two as separate entries rather than as synonyms.
Does Sidr & Stone sell taggiasca olives?
No. We sell one olive product and it is an oil — a single-estate, rain-fed, organically grown extra virgin from a family grove on the plains outside Marrakech in Morocco. We do not sell table olives of any origin, and this article is not a route to buying any.
Why are taggiasca olives so often sold in oil rather than brine?
Because the designation permits it as a distinct product type. Pitted olives may be dried and then covered with extra virgin olive oil at 30% to 40% of the weight of the olives, and the label must state that percentage. It is a different preparation from whole olives in brine, not a superior version of them.
Where can you buy taggiasca olives?
Italian delicatessens, specialist grocers, and a number of Ligurian producers who ship directly. Check the pack for the registered name and the product type, and remember that where the olives sit in liquid, the declared net weight is the drained weight.
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 odd thing about taggiasca olives is how long the name did all the work on its own. It is one of the most recognisable olives in Italy — the specification lists Ligurian rabbit among the traditional dishes of which the olive is an essential part — and until 2023 the word on the jar was a variety and nothing more. Now there is a document behind it, and the document is far more specific than most people would guess: a size in millimetres, three sensory medians, a salt range, a minimum of forty-five days, a ban on chemical debittering, and a rule about how much oil may go into a jar.
None of that tells you whether you will like them. What it tells you is what somebody has to test against before the phrase may appear on a label, and that is the only sort of guarantee a name can honestly carry. Take the designation as evidence rather than as a verdict, and read the rest of the jar — the product type, the drained weight, the percentage of oil — with the same eye.
And if the jar in front of you says only taggiasca, that is not a fault. It is a cultivar name doing exactly as much as a cultivar name can do.
