Australian Olive oil fears fruitless
Manzanillo is the great table olive of Seville — plump, meaty, sold by the billion. So when Australian growers planted it hoping for oil and got modest yields, some feared they had made a costly mistake. They had not. The variety simply needed to be used for what it does best.
There is an old cautionary tale from the early days of the Australian olive boom, and it turns on a single, world-famous variety: Manzanillo. Growers planted it widely as an oil tree, then panicked when the oil yields came in low, fearing they would have to rip out whole plantings. The mass removal never happened — and the reason it never happened is the whole point of the story. Manzanillo is not really an oil olive. It is the finest table olive on earth, asked to do the wrong job.
The queen of table olives
Manzanillo — Manzanilla de Sevilla in its homeland — is very probably the most widely eaten table olive in the world. It comes from the Seville region of Spain and is prized for exactly the traits that make a great eating olive: a rounded, generous fruit with a remarkably small stone and a high ratio of flesh to pit, so there is a lot to eat and little to spit. Its flesh separates cleanly from the stone, it takes a cure beautifully, and it is the classic green Spanish olive of the tapas bar. Whole industries exist to grow, cure and sell it as food.
Why it disappointed as an oil tree
The oil problem is not that Manzanillo makes bad oil — it makes a lovely one — but that it makes relatively little of it, and awkwardly. It is a fleshy, high-moisture fruit, and that water makes it fiddly to press: extract it carelessly and yields are poor and the oil can be hard to separate. In the early, inexperienced years of a new olive industry, growers pressing Manzanillo without the right technique got exactly the low returns that sparked the panic. Better handling — easing off irrigation before harvest, adjusting the mill so the fruit is not crushed too fine — coaxes out far more of a genuinely fine, aromatic, vividly green oil. The oil is a bonus; the table olive is the main event.
The lasting lesson: right olive, right job
Strip away the dated Australian panic and a permanent truth remains, one that applies to any grower or buyer. Olive varieties are specialists. Some are bred for oil, some for the table, some genuinely do both but rarely equally well. Manzanillo is a table olive that can give oil; Picual is an oil olive you would not choose to eat. Plant a table variety for oil and you will feel cheated by the yield; buy a bottle of single-variety Manzanillo oil and you should expect a small-batch, green, aromatic treat, not a cheap workhorse. Match the variety to the purpose and the disappointment evaporates.

Buying & using Manzanillo
- As a table olive it is a benchmark — plump, meaty, easy to eat, the classic green Spanish olive.
- As an oil, expect a small-batch, green, aromatic bottle, not a bargain everyday oil.
- Do not judge it by yield — its value is on the plate, with oil as a bonus.
- The wider rule: match the variety to the job, whether you are planting or buying.
Manzanillo olives: common questions
Is Manzanillo a table or oil olive?
Primarily a table olive — very likely the world’s most popular — though it is dual-purpose and can yield a fine oil in smaller amounts.
Why did Manzanillo worry Australian growers?
They planted it for oil and got low yields, fearing a costly mistake. In fact it is a table olive asked to do the wrong job; better milling technique improved the oil.
Where does Manzanillo come from?
The Seville region of Andalusia in southern Spain, where it is the classic green table olive, grown across Seville, Huelva and Badajoz.
What is Manzanillo oil like?
Fine, aromatic and vividly green, but relatively low-yielding and not very stable, so it is best enjoyed as a fresh, small-batch oil.
Why is it such a good eating olive?
It has a rounded, fleshy fruit with an unusually small stone, so there is plenty to eat, and its flesh cures beautifully and separates cleanly from the pit.
Manzanillo frightened some early Australian growers because they asked a table olive to be an oil tree, then blamed the tree for the poor yield. That is like planting a dessert apple and cursing it for making thin cider. Manzanillo is the queen of eating olives — small stone, generous flesh, a joy cured green. It can give a lovely aromatic oil in modest amounts if you mill it well, but that is a bonus, not its purpose. The rule outlives the panic: plant and buy the right olive for the right job.
