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%.
Olive oil is beloved worldwide for its delicious flavor and versatility in cooking. But have you ever wondered how many olive trees it takes to produce this treasured “liquid gold”? In this comprehensive guide, we’ll examine olive oil yields to uncover how much oil a single tree can generate.
Olive Tree Productivity
On average a mature olive tree can produce anywhere from 15-20 kg (33-44 lbs) of olives per year. Olive trees start bearing fruit after 5-8 years reaching peak production around 20 years old. Yields gradually decline after 50 years, but trees may remain productive for centuries.
Exact olive yield depends on factors like climate, variety, farming practices, and the tree’s overall health and age. Well-cared for trees in ideal growing regions can produce up to 40-50 kg (80-110 lbs) annually. So while olive trees live long lives, their fruit output from an individual tree is relatively modest.
Olive Oil Extraction Rate
It takes approximately 5 kg (11 lbs) of olives to make 1 liter of olive oil. So each olive tree can generate around 3-4 liters (31-42 quarts) of olive oil per year. Top producers may yield up to 5 liters (1.3 gallons) under optimal conditions.
On average, the oil content of olives falls between 10-20% by weight. With standard 500 ml bottles, a single olive tree can produce about 6 bottles of olive oil annually. While respectable, this is still a relatively small volume of oil from each tree.
Estimating Tree Numbers for Commercial Production
To generate meaningful olive oil quantity, commercial groves require many trees planted across substantial acreage:
- An acre of olive trees contains around 100-150 trees.
- 1 hectare (2.5 acres) typically has 200-300+ trees.
- An olive grove with 500 trees can produce about 2,000 liters (528 gallons) annually.
- At 3 liters per tree, 1,000 trees will yield 3,000 liters (793 gallons).
- 10,000 trees can produce 30,000 liters (7,925 gallons).
- Large commercial farms may have over 100,000 trees.
So the more trees planted, the greater the potential olive oil volume from each yearly harvest.
Optimizing Olive Oil Yields
To maximize olive yields, growers should provide:
- Well-draining, fertile soil for strong tree growth.
- Consistent moisture and irrigation where dry.
- Sunny locations with minimal winter frost.
- Protection from strong winds.
- Regular fertilization, pruning, and pest control.
- Harvesting when oil content peaks.
- Gentle mechanical harvesting to avoid bruised fruit.
- Quick processing within 24 hours of harvest.
Meeting olive tree requirements results in greater fruit quantities and higher oil content.
Factors Impacting Production
Several variables influence potential olive oil output:
- Tree variety – some cultivars naturally produce more.
- Tree age – peak yield around 20 years old.
- Climate and region – warm and sunny is better.
- Soil conditions – poor soils limit yields.
- Farming practices – impacts tree health.
- Crop maintenance – proper care boosts yields.
- Harvest method – gentle handling preserves oil content.
- Processing equipment – quality machinery maximizes oil extraction.
Consider all factors when estimating possible olive oil production.
Yield for Small Home Growers
For residential gardeners with just a few trees:
- Expect approximately 3-5 liters (0.8-1.3 gallons) of oil per tree.
- 5-10 trees can supply a family’s yearly olive oil needs.
- Small harvests must be processed at commercial mills.
- Coordinate timing with neighbors to improve efficiency.
- Weigh olives before pressing for oil content estimates.
- Oil yield ranges from 16-18% for small hand-harvested batches.
Just a handful of backyard trees may be adequate for personal use.
Pressing Olives into Olive Oil
To extract oil from harvested olives:
- Olives are crushed into paste using stone mills or steel presses.
- The paste is stacked in fiber mats and pressed to separate oil and water.
- Centrifuges or decanting then divides the liquids into oil and water components.
- The oil may be filtered before grading and bottling.
Proper equipment and handling optimizes oil extraction yields.
Pruning for Maximum Productivity
Frequent pruning helps maximize olive oil production by:
- Removing old wood and encouraging new fruitful shoots.
- Improving light and air penetration for tree health.
- Balancing growth and directing energy into fruiting.
- Facilitating harvest with open canopies.
- Rejuvenating old trees by severe pruning back to stumps.
- Managing pests/diseases by eliminating infections and dead wood.
Along with other cultivation techniques, pruning sustains olive productivity over time.
On average, a mature olive tree can yield 3-5 liters of olive oil yearly. However, actual production varies significantly based on climate, variety, tree age, and growing conditions. Home growers may only require 5-10 trees to supply their family’s needs. But commercial operations need tens of thousands of trees across many acres to generate meaningful olive oil quantities. With proper horticultural practices, olive trees can continue providing delicious oil for generations.
What does the amount of oil produced by an olive tree depend on?
An olive tree produces more or less oil based on the following parameters:
- age and size of the tree crown
- whether the olive tree is rain-fed or irrigated
- the weather conditions during the year
- the cyclical yield
- agronomic care: fertilizers, treatments and pruning
Lets detail them a little.
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.
