Olive Varieties — A Field Guide

The cultivar sets the ceiling. The harvest decides how close the oil gets to it.

Why variety matters

Two oils can share a polyphenol count and behave nothing alike. Cultivar determines the shape of the phenolic profile — how much oleocanthal against oleacein, how much hydroxytyrosol survives the press, how long the oil holds before oxidation dulls it. It also determines whether you can take a spoonful neat every morning, or whether you will quietly stop after a fortnight.

What the numbers do not say

Harvest date, altitude, drought, milling temperature and time between picking and pressing move the count as much as the cultivar does. A ripe Picual can fall below an early-harvest Arbequina. Read the certificate of analysis, not the varietal name — then read them together.

The Cultivars

01SPAIN · JAÉN, ANDALUSIA

Picual

The workhorse. The most planted olive on earth.

Picual carries the highest oleic acid content of the common cultivars and one of the highest natural phenolic loads — which is why it resists oxidation longer than almost anything else in the press. Bitter, green, unmistakably peppery. It does not flatter a dish; it argues with it.

Polyphenols
Typically high — 400–900 mg/kg in early-harvest oils
Stability
Exceptional. Highest oxidative resistance of the four
Character
Bitter, grassy, tomato leaf, strong throat catch
In the house
Tropicual Everyday — 100% Picual, 714 mg/kg
02SPAIN · CATALONIA

Arbequina

The approachable one — and, harvested early, a deceptive giant.

Arbequina is small-fruited, high-yielding and the cultivar most people meet first, usually as a soft, buttery supermarket oil. That reputation misleads. Picked green and pressed cold within hours, Arbequina can carry a phenolic load that outruns cultivars twice its reputation — our SP360 runs at 1,711 mg/kg. Variety sets the ceiling; harvest date decides how close you get to it.

Polyphenols
Wide range — low when ripe, very high when early-harvested
Stability
Moderate. Lower oleic acid than Picual
Character
Fruity, almond, apple, gentle bitterness

SP360 Special Production — 1,711 mg/kg · Onsuri Arbequina — 1,504 mg/kg

Arbosana

Arbequina's smoother sibling, bred for the hedgerow.

Arbosana is a low-vigour cultivar suited to high-density planting, which is why it now grows far beyond Spain — Jordan, Portugal, Chile, Australia. The oil is fruit-forward and rounder than a Picual, with a late pepper that arrives at the back of the throat rather than the front of the tongue. Easier to drink neat, which matters if you are taking a spoonful daily rather than dressing a salad.

Polyphenols
Moderate to high — 400–700 mg/kg typical
Stability
Good. Holds well through the year
Character
Fruit-forward, soft, delayed peppery finish
In the house
Onsuri Arbosana — 651 mg/kg, ranked 3rd best Arbosana in the world

Cornicabra

The goat's horn — Spain's second cultivar, and its most overlooked.

Named for the curved, horn-shaped fruit. Cornicabra grows on the hard, dry central plateau, and the drought stress shows up in the bottle: high oleic acid, a dense phenolic profile and a long shelf life. The oil is more aromatic than Picual, with apple and avocado notes underneath the bitterness. Rarely exported at scale, which is precisely why it is worth seeking.

Polyphenols
High — comparable to Picual in early harvest
Stability
Very good. High oleic acid, drought-hardened fruit
Character
Aromatic, apple and avocado, firm bitter finish

Ranges are typical, not guaranteed. Every bottle we sell ships with its own certificate of analysis.

The harder the olive tree strains to live, the more its fruit carries — and the more the oil gives back to the body that receives it.
