How much oil does an olive tree produce?

How much oil does an olive tree produce?

Olive trees are valued worldwide for producing a source of liquid treasure: olive oil. However, a question that often arises is: how much oil can a single olive tree produce?

Generally, to produce 1L of olive oil, between 4 and 5kg of olives are needed. In this preparation, the fruit yield is around 20-25%. That is, for every 5kg of olives that are processed, around 1L of olive oil is obtained.

This performance is even lower when it comes to producing quality extra virgin olive oil. Between 8 and 10kg of olives are needed to make 1L of oil, lowering its yield percentage to 10%.


Factors that Influence the Production of Olive Oil:

There are several factors that can influence the amount of oil that an olive tree produces. These factors are:

1. Variety of Olive:
Depending on the variety of olive, its oil yield will be different.

For example, varieties such as Picual, Arbequina and Hojiblanca are known for their unique production characteristics thanks to their high fat content (over 20%), which makes them capable of producing more oil.

While varieties such as Hojiblanca or Manzanilla Villalonga have a lower yield, although of quality.

2. Climate and Cultivation Conditions:

Climate, altitude and other environmental aspects can influence the health of the olive tree and therefore influence its oil production.

In areas with a warm Mediterranean climate
 such as Andalusia and the Valencian Community, the yield of olives is higher compared to cold and sunless areas.

However, if there are periods of frost or drought in these warm areas, the yield of the olive trees is much lower, and may become invalid.

3. Age of the Olive Tree:

The age of the olive tree also plays an important role.

When an olive tree is born until it reaches 6 years old, the amount of olives it produces is relatively low because it is still forming. It is when it reaches its maturity period, between 6 and 19 years, when its quantity of olives increases and, therefore, it can produce more oil.

However, older olive trees, such as centenary and millennial ones, produce a smaller amount of olives due to their advanced age of maturity. However, these fruits from ancient olive trees are larger and of higher quality.

4. Care and Maintenance:

Proper pruning, balanced irrigation and careful management of olive trees contribute to optimal performance.

A well-cared for olive tree 
that has not been cultivated in an intensive model (where the trees are close to each other with hardly any space), will produce high quality olives, since it has sufficient lighting and can develop better.


Approximate Olive Oil Production Figures:

The amount of oil that an olive tree can produce varies, but here we offer approximate figures based on the annual production of an adult olive tree:

Young Olive Trees: A young olive tree, about 5 to 8 years old, can produce around 5 to 10 liters of oil per season.

Mature Olive Trees: A mature olive tree, 20 years old or more, can produce between 20 and 40 liters of oil or even more in ideal conditions.

Centennial and Millennial Olive Trees: Although the majority of centuries-old and millennial olive trees produce less quantity of olives than young olive trees, their olives are larger, and can produce more than 50 liters of oil.
