Why do olive varieties matter?
Because olive varieties help explain why olive oils can taste so different. An olive cultivar, a cultivated variety of the olive tree, can influence aroma, bitterness, pungency, oil yield and composition. But the cultivar is only part of the story.
Why can the same cultivar produce different olive oils?
Because where the olives grow matters. Across the Mediterranean, generations of farmers selected olive trees that performed well in their local conditions. Soil conditions, altitude, rainfall and microclimate can influence how a cultivar expresses itself.
Can an olive cultivar be grown somewhere else?
Yes. But moving the cultivar does not move the place. The cultivar can travel. The place cannot. Plant Nocellara, a traditional Sicilian cultivar, in Tuscany and Tuscany does not become Sicily. Plant Frantoio, a traditional Tuscan cultivar, in Sicily and Sicily does not become Tuscany.
Does that mean one place is automatically better?
No. It explains the diversity. Cultivar and place shape the fruit; the particular growing season, harvest timing, fruit condition, processing and storage help determine what eventually reaches the bottle.
What is an olive cultivar?
A cultivar, short for cultivated variety, is a distinct olive variety selected and propagated for particular characteristics.
Does the cultivar determine how an olive oil tastes?
No. It influences the oil, but where the olives grow, when they are harvested and how they are processed also matter.
Are green olives and black olives different varieties?
Not necessarily. Green, purple and black often describe different stages of ripeness of the same cultivar.
What is monocultivar olive oil?
Monocultivar olive oil is made from one olive cultivar. A blend combines two or more. Neither is automatically better.

What Is an Olive Cultivar?
A cultivar, a cultivated variety maintained through propagation, is a recognizable type of olive tree with particular inherited characteristics. Cultivars can differ in fruit size, ripening behavior, oil content, agricultural performance and the characteristics they can contribute to an olive oil.
But thinking of cultivars as standardized flavor formulas is a mistake.
Traditional olive cultivars developed within agricultural landscapes. Farmers preserved and propagated trees that worked well under local conditions and for local needs. Over generations, that helped create the extraordinary diversity found across Italy and the wider Mediterranean.
The important idea is simple: a cultivar brings characteristics and potential; the place where it grows helps determine how that potential is expressed.
Why Can the Same Olive Cultivar Produce Different Oils?
Because an olive tree does not grow in a laboratory.
A cultivar planted in another location keeps its varietal identity, but its growing environment changes. Soil conditions, elevation, exposure, rainfall, temperature and water availability can all be different.
A cultivar retains its varietal identity when it is planted elsewhere, but it develops under a different combination of climate, soil conditions, elevation, water availability, exposure and farming conditions.
That is why planting Nocellara in Tuscany does not recreate Sicily, and planting Frantoio in Sicily does not recreate Tuscany. The cultivar moved; the environment did not move with it.
Then another layer begins. The particular growing season, fruit maturity, harvest timing, condition of the olives, processing and storage further influence the oil that eventually reaches the bottle.
Fruit condition matters too. Olives that are damaged or held too long before milling can produce a different result from sound fruit processed promptly.
This is why two bottles made from the same cultivar do not have to taste identical.
Why Does the Mediterranean Have So Many Olive Cultivars?
Olive growing developed across an enormous range of Mediterranean environments. Spain, Portugal, Italy, Greece, Croatia, Albania, Turkey, Tunisia and Morocco contain different climates, landscapes and agricultural traditions—and considerable diversity exists even within each country.
The International Olive Council's World Catalogue of Olive Varieties documents this diversity across olive-producing countries.
Italy is an especially clear example. Its olive landscape stretches from northern growing areas through Tuscany, Umbria and Puglia to Calabria, Sicily and Sardinia. Within those regions are still smaller growing areas with their own conditions and traditional cultivars.
The result is not one standard “Italian olive.” It is a mosaic of olive varieties and territories.
Why Does Italy Have So Many Olive Cultivars?
Italy's geography changes dramatically over relatively short distances. Mountains, hills, plains, islands and coastlines create different soils, elevations, rainfall patterns and microclimates.
Over centuries, farmers selected and propagated olive trees suited to local agricultural needs and production systems. That process produced an unusually rich cultivar heritage.
CREA, Italy's Council for Agricultural Research and Economics, documents hundreds of Italian cultivar denominations and also cautions that synonymy—different names used for the same variety—makes simple cultivar counts difficult.
That diversity is why “Italian olive oil” cannot describe a single flavor profile. For the same reason, even “Sicilian olive oil” or “Tuscan olive oil” covers substantial diversity.
See our guide to Italian olive oil regions for the larger geographical picture.
Which Italian Olive Cultivars Should You Know?
You do not need to memorize hundreds of cultivar names to understand olive oil. A few important examples show how diverse the Italian olive landscape can be.
Frantoio
Frantoio, a traditional cultivar strongly associated with Tuscany and central Italy, is widely used for olive-oil production. Its oils can show green and herbaceous characteristics with varying bitterness and pungency.
Leccino
Leccino, another important central Italian cultivar, is now grown well beyond its traditional territory. Its widespread cultivation is a useful reminder that moving a cultivar does not reproduce the original growing environment.
Coratina
Coratina, a cultivar strongly associated with Puglia, can produce intensely bitter and pungent oils and is frequently associated with substantial phenolic content.
But “Coratina” is not a laboratory result. Exact polyphenol content depends on the actual oil and must be measured. Our guide to polyphenol-rich olive oil explains the distinction.
Carolea
Carolea, one of Calabria's important traditional cultivars, can be used for both olive oil and table olives.
Bosana
Bosana, a cultivar strongly associated with Sardinia, is an important oil variety on the island and can produce oils with noticeable bitterness and pungency.
Taggiasca
Taggiasca, a cultivar associated with Liguria, is used for both table olives and olive oil and is commonly associated with comparatively delicate oils.
What About Sicily?
Sicily makes Mediterranean olive diversity particularly easy to understand. The island does not have one uniform growing environment or one “Sicilian olive.” Different territories have preserved different cultivars through long local agricultural traditions.
Nocellara del Belice, a cultivar associated with western Sicily, is valued both as a table olive and for olive oil.
Tonda Iblea, a cultivar associated with southeastern Sicily and the Monti Iblei, is known for oils that can express distinctive green and tomato-like aromatic characteristics.
Biancolilla, Cerasuola, Moresca and Nocellara Etnea are further examples of Sicily's cultivar diversity.
The point is not to memorize the names. It is to understand why they exist: olive agriculture developed locally, not as a standardized industrial system.
What Are Some Important Cultivars Outside Italy?
The same principle appears throughout the Mediterranean.
Spain has cultivars such as Picual, Arbequina and Hojiblanca. Greece has Koroneiki and numerous traditional cultivars documented by the Institute of Olive Tree, Subtropical Crops and Viticulture of ELGO-DIMITRA.
Portugal has cultivars including Galega, Cordovil, Cobrançosa and Verdeal, documented by Casa do Azeite, the Portuguese Olive Oil Association.
Croatia has Oblica. The Croatian Ministry of Agriculture connects the character of Bračko maslinovo ulje PDO not only with Oblica but with the island's environmental conditions and production practices.
Turkey has cultivars including Ayvalık, Memecik and Gemlik. Morocco is strongly associated with Picholine Marocaine, while Tunisia has important cultivars including Chemlali and Chetoui.
Albania also combines indigenous olive heritage with introduced cultivars. A study published through Albania's Ministry of Agriculture and Rural Development documents the country's cultivar structure and changing olive landscape.
These are not simply different names for olives. They are evidence of an agricultural landscape that developed differently from place to place.
Are Green Olives and Black Olives Different Varieties?
Not necessarily. Olive color commonly changes as the fruit ripens.
Young fruit is generally green and can progress through other colors toward purple and darker stages as maturity advances, depending on the cultivar.
This matters because harvest timing can also change the characteristics of the resulting olive oil.
So “green olive” and “black olive” should not automatically be understood as cultivar names.
Are Table Olives and Olives for Olive Oil Different?
Sometimes, but not always.
Some cultivars are primarily valued for oil production. Others are particularly suitable as table olives. Some are dual-purpose cultivars, meaning they can be used for both.
Nocellara del Belice is a familiar Italian example.
Table olives normally undergo curing or fermentation before eating. Olives intended for oil are harvested and processed through crushing, malaxation and separation. See how olive oil is made for the complete process.
Does Cultivar Determine How Olive Oil Tastes?
No. It contributes to the result.
A cultivar can influence an oil's potential aroma, bitterness, pungency and composition. But the finished sensory profile also reflects where the fruit grew, the particular growing season, its maturity at harvest and what happened between the tree and the bottle.
This is why descriptions such as “Tonda Iblea tastes like tomato” or “Coratina is bitter” are useful tendencies, not guarantees.
The same cultivar can express itself differently in different places and under different production conditions.
Our guide to how to taste olive oil explains how fruitiness, bitterness, pungency and defects are evaluated in the finished oil.
Does Cultivar Determine Polyphenol Content?
No. Cultivar can influence phenolic composition, but it cannot establish the exact polyphenol concentration of a particular olive oil.
The same cultivar can have different polyphenol levels from one oil to another. Growing conditions, the particular growing season, fruit maturity, harvest timing, processing and storage also matter.
If a producer gives an exact number in mg/kg, that number should come from measurement of the oil—not from assumptions about the cultivar.
Bitterness and pungency can provide sensory information, but your mouth is not a laboratory. Taste cannot establish an exact polyphenol concentration.
What Is Monocultivar Olive Oil?
Monocultivar olive oil, also called monovarietal olive oil, is produced from one olive cultivar.
That can make cultivar identity an interesting part of the oil's story. It does not automatically make the oil superior.
Monocultivar describes composition, not quality.
A producer can also intentionally combine two or more cultivars. A well-designed blend can use different cultivars for complementary aromatic, structural or sensory characteristics.
Is a Blend Worse Than a Monocultivar?
No.
A blend simply means that more than one cultivar contributes to the oil. Neither “blend” nor “monocultivar” tells you whether the olives were healthy, harvested at the right moment, processed carefully, stored correctly or whether the finished oil meets high chemical and sensory standards.
Instead of asking only “Is it monocultivar?”, ask:
What cultivars were used? Where were the olives grown? When were they harvested? How was the oil produced? What evidence does the producer provide about the finished oil?
How Should You Read Cultivar Information on an Olive Oil Label?
Treat the cultivar as useful information—not as a quality certificate.
Look for it together with:
- origin — where the olives were grown;
- harvest information — when the fruit was harvested;
- lot or batch information — which production the bottle belongs to;
- producer information — who produced the oil;
- packaging and storage — how the oil is protected;
- laboratory measurements — particularly when numerical chemical claims are made.
Slovenia's Laboratory of the Institute for Oliveculture at ZRS Koper, for example, works with chemical analysis, sensory evaluation and olive-oil authenticity. It illustrates the difference between knowing the identity of an olive and evaluating the oil actually produced from it.

Tonda Iblea + Nocellara: The Cultivars in Lumìa
Our Lumìa Italian Extra Virgin Olive Oil combines Tonda Iblea and Nocellara, two Sicilian olive cultivars.
Those cultivar names are part of the oil's identity. They are not our proof of quality.
The Fall 2026 harvest continues that Tonda Iblea and Nocellara identity. Exact chemical measurements belong to the finished oil from that production and should not be inferred from the cultivar names themselves.
The Bottom Line
Olive oils are different because olives are not standardized ingredients.
Cultivar matters. Place matters. Season matters. Harvest and production matter. The same cultivar grown somewhere else does not automatically reproduce the same fruit or the same oil.
The easiest way to remember it is this:
The cultivar can travel. Technique can travel. The place cannot.
So when you see Coratina, Frantoio, Picual, Koroneiki, Nocellara or Tonda Iblea on a label, do not read the cultivar name as a flavor formula or a guarantee of quality. Read it as one part of the story.
Then look for the rest: where the olives grew, the growing season, when they were harvested, how the oil was produced and what the finished oil can actually demonstrate.
For another evidence-first look at olive-oil labels and measurable claims, see the New York Olive Oil Organization's Olive Oil Guide.

Frequently Asked Questions
What is an olive cultivar?
An olive cultivar is a cultivated variety of the olive tree selected and propagated for particular characteristics.
Why do olive oils from different places taste different?
Cultivar is only one factor. Soil, climate, altitude, rainfall, the particular growing season, fruit maturity, harvest timing, processing and storage can all influence the finished olive oil.
Can the same olive cultivar taste different when grown somewhere else?
Yes. The cultivar remains the same variety, but changing the growing environment can change how its characteristics are expressed in the fruit and resulting oil.
Are green and black olives different cultivars?
Not necessarily. Color often reflects the stage of ripeness, so fruit from the same cultivar can change from green toward darker colors as it matures.
What is monocultivar olive oil?
Monocultivar olive oil is produced from one olive cultivar. A blend combines two or more cultivars. Neither is automatically better.
Does cultivar determine polyphenol content?
No. Cultivar can influence phenolic composition, but growing conditions, the particular growing season, maturity, harvest, processing and storage also matter. Exact polyphenol concentrations require measurement of the oil.
Does cultivar determine olive oil flavor?
No. Cultivar can influence flavor and aroma, but the growing environment, season, harvest and production also influence the finished sensory profile.
Is monocultivar olive oil better than a blend?
No. Monocultivar and blend describe how many cultivars were used, not the quality of the finished olive oil.
