PDO, PGI or organic olive oil: what is the real difference?

PDO and PGI are about origin, organic is about how the olives are grown. What each label really guarantees, what it does not, and why one oil can carry more than one.

On shop shelves and online stores the labels keep multiplying: PDO, PGI, organic, "100% Italian". They all sound like promises of quality, but they do not say the same thing. Some are about where the oil comes from, others about how the olives were grown. And none of them, on its own, guarantees that the oil in your hands is fresh and good.

In this guide we look at what each certification means, how to recognise it on the label and how to use it to choose.

At a glance

	PDO	PGI	Organic
What it guarantees	origin from a precise area and a strict production specification	origin from a wider territory	a farming method without synthetic chemicals
Link to the territory	very close	strong	none (it can come from anywhere)
EU logo	yellow and red	yellow and blue	green leaf
Who checks it	authorised control body	authorised control body	organic certification body

The most important thing to remember: PDO and PGI are about origin, organic is about method. That is why the labels can be combined.

First of all: "extra virgin" is something else

"Extra virgin" is not a certification but a product category. An oil is extra virgin if it stays within precise chemical limits (free acidity, peroxides and other parameters) and if a panel of tasters finds no defects. If it fails one of these tests, it is "virgin" or "lampante".

PDO, PGI and organic come on top of that: a PDO oil is always extra virgin, but not every extra virgin oil is PDO.

PDO olive oil: origin and production specification

PDO stands for Protected Designation of Origin, written DOP (Denominazione di Origine Protetta) on Italian labels. It is the European recognition that ties a product most closely to its land. For a PDO oil:

the olives must be grown within the defined area;
they must be milled into oil in that same area;
only the cultivars listed in the specification may be used, often native ones;
the oil must meet chemical and sensory parameters that are stricter than the legal ones for extra virgin.

Each PDO has its own specification. The Monti Iblei PDO, in south-eastern Sicily, is divided into eight sub-zones, each with its own cultivars. Our Il Distinto is Monti Iblei PDO Gulfi, made only from Tonda Iblea olives; Il Galante is Monti Iblei PDO Valle dell'Irminio, from Moresca olives. If you want to know more about sub-zones and cultivars, read our guide to DOP Monti Iblei olive oil.

On the label you will find the yellow and red logo and the full name of the designation, often with the sub-zone. An oil that calls itself "PDO" without saying which designation deserves a second look.

PGI olive oil: a wider territory

PGI stands for Protected Geographical Indication, IGP (Indicazione Geografica Protetta) on Italian labels. Here too the origin is guaranteed and there is a specification to follow, but the territory is wider and the rules on cultivars are usually less restrictive.

For Sicilia PGI oil the area is the whole region: the olives must be grown in Sicily and milled in Sicily. It is a guarantee of genuinely Sicilian oil, which also makes room for cultivars and territories that do not fall within a PDO.

This is the case of our Il Primizio, Sicilia PGI made only from Verdese olives: a little-known Iblean cultivar with a light, grassy fruitiness. On the label, PGI is recognised by its yellow and blue logo.

Organic olive oil: the method, not the origin

Organic says nothing about provenance: it tells you how the olives were grown. An organic oil comes from olive groves where:

no synthetic pesticides or chemical fertilisers are used;
soil fertility is maintained with green manure, animal manure and tillage;
pests are controlled with traps, mechanical means and permitted products;
a certification body inspects the fields and the mill every year.

On the label you will find the European Union's green leaf (the EU organic logo), the code of the control body (on our oils: IT BIO 018) and the origin of the raw materials ("Agricoltura Italia", "Agricoltura UE"…, meaning Italian or EU farming).

An oil can be organic and come from any country. So if origin matters to you as well, look for organic together with a geographical indication or a declared Italian origin, as with our L'Amabile, organic and 100% Italian.

The labels add up

Since they answer different questions, one oil can carry several certifications at once. Here is how ours line up:

Oil	Certifications	Cultivar	Profile
Il Distinto	Monti Iblei PDO Gulfi + organic	Tonda Iblea	intense fruitiness
Il Galante	Monti Iblei PDO Valle dell'Irminio + organic	Moresca	medium fruitiness
Il Primizio	Sicilia PGI + organic	Verdese	light fruitiness
L'Amabile	organic, 100% Italian	blend	delicate

An organic PDO oil gives you both guarantees: you know where it comes from and how it was grown.

What certifications do not guarantee

No label, on its own, tells you everything. In particular:

freshness: a PDO oil from three years ago is still a tired oil. Always check the harvest season stated on the label;
taste: two PDO oils from the same area can be very different, depending on the cultivar and the care taken at the mill;
storage: an excellent oil kept in the light and in the heat spoils within a few months.

To judge an oil you also need the analysis data and your own nose. Two guides can help: how to read acidity, polyphenols and peroxides on the label and how to recognise a genuine extra virgin olive oil.

Label wordings not to confuse with certifications

Some phrases on Italian labels look like guarantees but are not:

"100% italiano" or "olio di oliva italiano" (100% Italian, Italian olive oil): states where the olives were grown and milled. It is useful, mandatory information, but it is not a production specification: it says nothing about cultivar or method;
"imbottigliato in Italia" or "prodotto in Italia" (bottled in Italy, produced in Italy): refers to the packaging, not to the olives;
"miscela di oli di oliva originari dell'UE" ("blend of olive oils of European Union origin" on English labels): olives from several countries, with no precise indication;
"prima spremitura a freddo" and "estratto a freddo" ("first cold pressing" and "cold extraction"): regulated wordings about the processing temperature, which say nothing about origin.

Which one to choose

It depends on what you are looking for and how you use the oil:

For raw use and dishes where the oil is the star (bruschetta, pulses, carpaccio): a PDO monocultivar expresses its territory to the full. Il Distinto if you love bold flavours, Il Galante if you prefer balance.
For fish, vegetables and delicate dishes: a light fruity oil such as Il Primizio Sicilia PGI.
For everyday cooking, including baking and frying: an organic oil of Italian origin such as L'Amabile, also available in 3 and 5 litre family sizes.

In short

PDO and PGI guarantee origin, with a closer link to the territory for PDO. Organic guarantees a farming method free of synthetic chemicals, but not origin. The labels can be combined, and an oil with more than one gives you more guarantees. None of them, however, replaces the simplest checks: harvest season, declared analyses and good storage.
