Nocellara Olives: The Cultivar, the PDO, and the Castelvetrano Question

Nocellara olives are the big, bright green, unusually firm Sicilian olives that turn up in every good deli and a fair number of supermarket tubs — and quite often under a different name altogether. The registered name is Nocellara del Belice, it has been a protected designation of origin since January 1998, and its specification is a good deal more specific than anything on the packaging suggests. We read the register entry and the dossier behind it rather than the retail copy, which is where most of the interesting detail turns out to be hiding.

For our own oil, see our cold-pressed organic Marrakech olive oil.


The Short Answer

  • Nocellara is short for Nocellara del Belice, a Sicilian cultivar and the registered name of a protected designation of origin, file PDO-IT-1551, protected from 21 January 1998.
  • The designation is registered under product category 147 — fruit, vegetables and cereals — which is to say it protects the table olive, not an oil.
  • Its area is three communes and no more: Castelvetrano, Campobello di Mazara and Partanna, in the province of Trapani in western Sicily.
  • The dossier describes the product as a table olive in two traditional categories only — black and green — and states that the harvest is done by hand, with processing started quickly afterwards.
  • The label rule is unusually concrete: designated olives must be packed in dedicated containers and the label must show the year of production alongside the words "Nocellara del Belice — Protected Designation of Origin".
  • Castelvetrano is not a registered name. We filtered all 4,011 entries in the register and found nothing containing the word. It is the town at the centre of the designation, used commercially as the olive's name.
  • The same cultivar sits behind a second designation on the oil side, Valle del Belice (PDO-IT-0258), and the same producers' association is named in both dossiers.
  • Sidr & Stone does not sell table olives. Our own product is a single-estate, rain-fed, organically grown olive oil from one family grove on the plains outside Marrakech.

What a Nocellara Olive Actually Is

Nocellara del Belice is a cultivar of the olive — a named variety propagated by cutting or graft, so that every tree carries the same genetics as the one before it. It is grown in western Sicily and it is unusual in being genuinely dual-purpose: good enough on the table to be cured whole, and oily enough to be worth milling. The dossier puts it precisely, describing the recognition over the last two centuries of the cultivar's "double vocation", after which production divided between oil and table olives.

For the table, the fruit is treated in one of two ways: green, before full ripening, or once ripe. That is the whole of the designation's product description — two traditional categories, black olives and green olives. Everything else you read about the variety, including every tasting note, comes from somewhere other than the specification.

The Register Entry, and the Three Communes It Names

We pulled the whole eAmbrosia register — 4,011 entries — on 28 August 2026 and filtered it for the name. Exactly one entry came back.

Field What the register holds
Registered name Nocellara del Belice
File number PDO-IT-1551
Type PDO — protected designation of origin
Product category 147 — fruit, vegetables and cereals
Status Registered
Protected from 21 January 1998
Registering publication Official Journal L 15, 21 January 1998
Geographical area The communes of Castelvetrano, Campobello di Mazara and Partanna, province of Trapani
Summary sheet languages Danish, Dutch, Finnish, French, German, Greek, Italian, Portuguese, Spanish, Swedish — no English version

That last row is worth dwelling on, because it explains why so little accurate detail about this olive circulates in English. The summary sheet the Commission holds for Nocellara del Belice exists in ten languages and English is not among them. Anyone writing about it in English is either reading one of those ten or repeating somebody who did. We read the French version, which is where the specifics below come from.

The dossier was filed under Article 17 of Council Regulation (EEC) No 2081/92, as national file number 133, by a cultural association called Cultori della Nocellara del Belice with an address in Castelvetrano; the Commission recorded the complete file as received on 21 October 1996. On the origin, it is brief and careful: references to olive growing in the Belice valley go back to the period of the Greek colonies of eastern Sicily. On method it is briefer still, but the one specific it does give is the useful one — the harvest is carried out by hand, with processing begun quickly so that the traditional curing can follow.

Nocellara or Castelvetrano? One Olive, Two Names

This is the question the whole subject turns on, and the answer is simple once you look at where the designation's boundary sits. Castelvetrano is one of the three communes in the protected area — the one the applicant association was based in. Somewhere along the export route, the town's name became the trade name for the olive, particularly in the United States. The variety did not change. The registered name did not change either. Only the label did.

Name you will see What it is In the EU register?
Nocellara del Belice The registered PDO name for the table olive Yes — PDO-IT-1551, protected 21 January 1998
Nocellara The cultivar name, used loosely and often on its own No entry is registered under that name alone
Castelvetrano A commune inside the designated area, used commercially as the olive's name No protected name containing the word appears anywhere in the register
Valle Belice A Sicilian wine geographical indication Yes — PGI-IT-A0811, protected 19 February 1999. Nothing to do with olives
Santa Margherita di Belice A Sicilian wine designation of origin Yes — PDO-IT-A0798, protected 14 April 2004. Also nothing to do with olives

The bottom two rows are the trap. "Belice" appears three times in the register and only one of those is the olive; the other two are wine. Seeing a Belice name on a Sicilian label is not the same as seeing the table-olive designation, and the same confusion recurs across the whole register — we set out the wider Italian picture in our guide to Italian olives.

One Cultivar, Two Designations, Two Registers

Nocellara del Belice is one of very few olives to hold protected names on both sides of the trade, and the register keeps the two entirely separate — different names, different file numbers, different product categories, four and a half years apart.

The table olive The olive oil
Registered name Nocellara del Belice Valle del Belice
File number PDO-IT-1551 PDO-IT-0258
Register category 147 — fruit, vegetables and cereals 146 — oils and fats
Protected from 21 January 1998 4 November 2002
Registering publication Official Journal L 15, 21.1.1998 Official Journal L 273, 21.8.2004
Applicant group named in the dossier Associazione "Cultori della Nocellara del Belice" Associazione "Cultori della Nocellara del Belice"

The last row is the detail that ties it together, and it is checkable: the application for the oil designation, published in the Official Journal of 18 November 2003, names the applicant group as the Associazione "Cultori della Nocellara del Belice" — the same body behind the table-olive dossier filed seven years earlier. One association, one cultivar, two registers. The cultivar percentages the oil designation requires, and the five other Sicilian oil designations alongside it, are a separate subject we have covered in our guide to Sicilian olive oil.


What the Dossier Says a Label Must Carry

Most protected-name specifications say something vague about packaging. This one does not. Table olives sold under the designation must be packed in dedicated containers, and the label must show — in addition to whatever the general food rules already require — two specific things: the year of production, and the indication "Nocellara del Belice — Protected Designation of Origin".

A year of production on a jar of olives is rarer than it should be, and it is the single most useful thing on the pack. It tells you which harvest you are eating, which for a cured green olive is the difference between firm and tired. If a tub carries the full registered name but no year, the designation's own rule has not been followed.

The rest of what must appear on a jar of table olives is set internationally rather than by any Italian designation — which fields are compulsory, which are optional, and how much of the jar is allowed to be brine. We have worked through those rules in full in our guide to Kalamata olives, and they apply here in exactly the same way.

The Objections Worth Taking Seriously

"Almost no Nocellara on sale carries the PDO — so what is the point?" A fair objection, and largely true: most tubs sold as Nocellara or Castelvetrano make no designation claim at all, and are perfectly good. The designation is not a quality gate on the cultivar; it is a gate on the name. What it gives you is a defined area of three communes, a stated curing tradition, a hand harvest and a year on the label. An unqualified tub gives you the variety and nothing else. Both can be excellent; only one is checkable.

"If the olive is identical, does the name matter?" The plant is identical, and Nocellara is now grown well outside the Belice valley. What differs is everything the register fixes — where the fruit was grown, how it was picked, how quickly it went into cure. Producers inside the area publish their address plainly: our note on Centonze covers an estate in Castelvetrano itself, and our piece on Partanna covers the neighbouring commune. They are different towns and different businesses, and both sit inside the same designated area.

"You sell oil, not olives — why write this?" Because it is the same register that governs the oil we do sell, and because the Nocellara case is the clearest illustration anywhere of a name doing two different jobs at once. Nothing here routes to our shelf; we stock no table olives of any origin.

And a refusal, for completeness. The search results around this olive keep asking whether Nocellara olives are healthy. We are not going to answer that. Olives are a food, table olives are cured in salt, and neither we nor the register has anything useful to say about what eating them does to anybody. If you have a reason to be watching your sodium intake, that is a conversation for a clinician, not for a blog.


Why Sidr & Stone

We should be clear about where we stand. Sidr & Stone sells one olive product and it is an oil from Morocco, not a Sicilian table olive, so nothing in this article leads anywhere near our shelf. What carries over is the method: we would rather quote a file number and a dossier than a tasting note, and we hold our own product to the same test.

  • 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 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, and it may show natural sediment, which is normal.
  • 100% natural — one ingredient, and nothing added.
  • 500 ml dark glass with a gold label — packaging that protects the oil from light.
  • Halal certified, with 10% of profits to charity as a brand-wide commitment, and fulfilment in the UK, EU, and US.

The asymmetry is worth naming rather than hiding. A designated Belice producer works to a published specification we have no equivalent of — we have not yet had a laboratory panel done, so we publish no polyphenol figure, no acidity result and no peroxide value for our oil. We will not tell you Sidr & Stone is better than a Valle del Belice oil; it is a different style from a different country, made with the same care and rather less paperwork behind it. We would sooner say that plainly than imply a number we have not measured.

Frequently Asked Questions

What are Nocellara olives?

They are olives of the Nocellara del Belice cultivar, grown in western Sicily. The name is also a protected designation of origin — file PDO-IT-1551, protected since 21 January 1998 — covering table olives from the communes of Castelvetrano, Campobello di Mazara and Partanna in the province of Trapani.

What do Nocellara olives taste like?

The specification does not say. It describes the product only as a table olive in two traditional categories, black and green, cured either before full ripening or once ripe, and publishes no sensory profile at all. Every tasting note you read for this olive is a seller's description rather than a registered characteristic — which does not make it wrong, but is worth knowing.

Are Nocellara and Castelvetrano olives the same thing?

Yes. Castelvetrano is a commune inside the protected area, and its name became the trade name for the olive, particularly in the United States. Nocellara del Belice is the registered name. No protected name containing the word "Castelvetrano" appears anywhere in the EU register.

Do Nocellara olives have to come from Sicily?

To carry the designation, they have to come from three named Sicilian communes and nowhere else. The cultivar itself is now planted well beyond the Belice valley, so an unqualified tub labelled "Nocellara" is describing the plant rather than the place.

Is Nocellara del Belice a table olive or an oil olive?

Both, which is unusual. The table olive is protected as Nocellara del Belice (PDO-IT-1551, category 147, fruit and vegetables); the oil pressed in the same valley is protected separately as Valle del Belice (PDO-IT-0258, category 146, oils and fats). The dossier calls this the cultivar's "double vocation".

What must a Nocellara del Belice label show?

Under the designation's own rules, the olives must be packed in dedicated containers and the label must carry, in addition to the general legal requirements, the year of production and the indication "Nocellara del Belice — Protected Designation of Origin".

Does Sidr & Stone sell Nocellara olives?

No. We sell one olive product, a single-estate cold-pressed olive oil from a family grove on the plains outside Marrakech in Morocco. We do not sell table olives of any origin. For the quality signals worth checking on a bottle of oil, see our guide to choosing a quality olive oil.

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

Nocellara del Belice is the rare case where the register is more interesting than the marketing. A dossier filed in 1996 by a cultural association in Castelvetrano, protected in 1998, covering three communes, describing a hand harvest and two curing traditions, and requiring a year of production on the label — all of it public, none of it printed on the tub, and none of it available in English at all.

The name, meanwhile, has been doing two jobs for decades. Sold as Castelvetrano it carries a town that is inside the designation but is not the designation. Sold as Nocellara it carries a cultivar that is now grown far beyond the valley. Only the full name, spelled out, points at anything you can check — and if it is on the jar, the year should be there too.

None of which is a reason to avoid the unlabelled ones. It is a reason to know what you are looking at, which is a better position to buy from than any adjective can give you.

Our cold-pressed organic Marrakech olive oil — single-estate, rain-fed, organically grown and unfiltered — is open for pre-order on its limited first harvest. Estimated shipping from November 2026. Fulfilment in the UK, EU, and US.
