How many kilos of olives are needed for one liter of olive oil?

The extra virgin olive oil of the highest quality, especially the AOVE from Jaén, is the result of a long tradition and a careful process that goes from the cultivation of the olive tree to obtaining the precious golden liquid, including the harvesting of the olive.

And one of the most common questions in the world of oil is: how many kilos of olives are needed for one liter of oil? If you have also wondered about this, keep reading because we will try to answer it.

The process of obtaining olive oil

Olive oil is extracted from olives through processes that combine crushing, grinding, and centrifugation or decantation. In each of these stages, the goal is to maximize the yield of the fruit without losing the organoleptic and nutritional properties that characterize extra virgin olive oil.

The amount of oil obtained per kilo of olives mainly depends on the intrinsic characteristics of the raw material, although modern technology has allowed the extraction process to be optimized to the maximum.

Factors that determine the yield of olives for oil

Variety and ripeness of the olive

The yield of olives for oil varies significantly depending on the variety of the olive and the degree of ripeness at the time of harvest. Younger olives, although they usually have a more intense flavor, have a lower fat content, while riper ones offer a higher percentage of oil.

How many kg of olives does an olive tree produce?

According to different studies, under good conditions, between 4 and 6 kilos of olives are needed to obtain one liter of oil. However, this figure can vary depending on the variety and cultivation conditions.

Additionally, other factors such as the water content and the cellular structure of the fruit
influence the extraction. Varieties with a higher proportion of oil achieve
higher yields, which is especially relevant for those seeking to produce high-quality oil.

Therefore, knowing when the olive is harvested is fundamental to ensure that the
fruit is harvested at the right time, which will allow maximizing both the
quantity and quality of the oil produced.

Intrinsic properties of the fruit

On the other hand, the properties of the olive also play a key role in extraction efficiency. The fat content, which can range between 20% and 25% of the fruit's weight, is the main determinant of how much oil can be obtained.

Thus, if ideal conditions are met, 5 kilos of olives with 20% fat content can produce approximately 1 liter of oil. Still, factors such as fruit quality or storage and transport conditions could affect the final result.

The influence of the cultivation process and care of the olive tree

Besides obtaining quality fruits, proper agronomic management of the olive tree is essential to get good oil yield. Correct pruning and adequate maintenance of the olive grove favor both production and olive quality.

For example, knowing when to prune an olive tree is fundamental to ensure that the
tree properly distributes its energy, which will favor the development of healthy,
quality fruits rich in oil. Moreover, the health of the olive tree is reflected not only in
the fruit but also in the quality of its leaves.

On the other hand, the properties of the olive leaf include antioxidant compounds
associated with greater resistance to diseases and stress, which indirectly can influence the yield and quality of the oil obtained.

Yield: figures and realities

According to data provided by reference oil mills, to produce one liter of olive oil, approximately between 4 and 6 kilos of olives are needed, depending on the following variables:

• Climatic conditions: seasons with extreme winters and summers can affect the quality and fat content of the olive.
• Cultivation and irrigation techniques: good agronomic management ensures healthier fruits richer in oil.
• Extraction methods: the technology used in milling and extraction directly influences the final yield.

It is important to highlight that yield is also measured based on the percentage of oil extracted. For example, a fruit with 22% fat content will offer better results than one with 18%, provided the extraction process is carried out under optimal conditions.

Relationship between the amount of olives and the final product

At this point, understanding how many kilos of olives are needed for one liter of oil is fundamental, not only from a production perspective but also to appreciate the effort behind each bottle of olive oil.

The density and weight of the oil, which vary slightly according to its composition, are aspects that can be consulted in detail in articles such as how much does a liter of oil weigh.

Knowing this will help you understand why olive oil is a product of
great value, and why each liter is the result of the sum of all these factors: the choice of harvest time, the quality and ripeness of the fruit, the agronomic management of the olive grove, and the efficiency of the extraction process.
