Early Olive Oil Production and Trade Development
Olive oil's journey from a local crop to a sought-after commodity was powered by evolving production techniques. Archaeological findings show that ancient communities developed methods of extraction that stood the test of time, shaping the oil's production for centuries.
First Cultivation and Oil Extraction Methods
The earliest traces of olive cultivation date back to around 5000 BCE on the Carmel coast in ancient Israel. Excavations between 2011 and 2013 at Ein Zippori, Israel, uncovered pottery fragments containing olive oil residues that are about 8,000 years old - remarkably similar to the olive oil we know today. Meanwhile, the Neolithic village of Kfar Samir offers an even deeper glimpse into early olive oil production, with evidence dating to 7600–7000 BP (roughly 5600 to 5000 BCE). Discoveries at this site, including olive presses and crushing stones, highlight the initial methods used to extract oil.
Early producers relied on simple tools: olives were crushed with stones, and the resulting mash was pressed using twisted sacks to extract the oil. Historical records suggest that even small variations in the pressure applied during extraction could influence the oil's flavor and texture. As production expanded during the Bronze Age, these manual processes gave way to more advanced systems. Heavy machinery, such as wooden beams and weight-stones, replaced hand-pressing, while producers refined techniques to separate oil from vegetable water more effectively.
This period of experimentation and improvement laid the groundwork for the Bronze Age, when demand for olive oil began to rise significantly.
Bronze Age Trade Route Growth
With improved production methods, olive oil output grew to meet the needs of a broader market. Standardized techniques emerged, such as placing olives in woven mats to press them, with the extracted oil collected in large vats. Evidence of this systematic approach is preserved in amphorae dating to around 3500 BCE. These advancements allowed producers to create surplus quantities, enabling long-distance trade.
Economic factors further fueled this expansion. In ancient Syria, olive oil was highly prized, valued at five times the price of wine. By the Late Bronze Age, Greece began cultivating olives on Minoan Crete and Cyprus. This led to surplus production, which was funneled into export networks throughout the eastern Mediterranean. The spread of olive cultivation was greatly aided by Phoenician and Greek settlers, who introduced olive trees to new regions. Their efforts established a vast network of interconnected trade routes across the Mediterranean, turning olive oil into a cornerstone of ancient commerce.
Mediterranean Trade Network Formation
As olive oil production expanded, two ancient civilizations - Phoenicians and Romans - played pivotal roles in transforming it into a key Mediterranean commodity. Their unique approaches to trade and organization elevated olive oil from a local product to an international staple.
Phoenician Maritime Trade Routes
The Phoenicians were trailblazers in olive oil distribution, creating the Mediterranean's first extensive trade network. Their routes connected North Africa, southern Europe, and the Levant, with key hubs like Carthage, Cyprus, and Alexandria. By transporting olive oil to far-reaching markets, they made it accessible across the known world.
They also excelled in quality control. Using advanced alabaster and clay packaging, they ensured the oil remained pure during long voyages. Standardized amphora designs simplified exports, while seals and branding guaranteed quality and origin, building trust among merchants and consumers.
The Phoenicians didn’t stop at distribution - they boosted production by introducing olive cultivation to new regions like Spain and Italy. They also refined pressing and preservation techniques in areas such as modern Lebanon and Israel, enabling long-term storage and export. Olive oil’s high value enriched Phoenician society and strengthened their maritime dominance. Their well-organized trade system, complete with specialized ports, warehouses, and merchant fleets, set the stage for olive oil’s widespread distribution throughout the Mediterranean.
Building on these innovations, the Roman Empire took olive oil trade to an entirely new level with its centralized, large-scale approach.
Roman Empire Trade Organization
The Romans revolutionized olive oil trade by shifting from merchant-driven practices to a state-controlled system. They expanded olive tree cultivation and refined production methods across their vast territories, making olive oil a cornerstone of both commerce and governance.
Rome’s olive oil trade was massive. The empire traded roughly 23 million kilograms of olive oil annually, with citizens consuming about two liters per person each month. Agriculture, heavily reliant on olive oil and wine, accounted for 70% of the empire’s income and employed 80% of its workforce.
Production facilities operated on an industrial scale. For instance, a factory in Libya housed 17 presses capable of producing 100,000 liters annually. Some producers managed outputs between 50,000 and 100,000 liters per year. Roman merchant ships, capable of carrying 75 tons or 1,500 amphorae, facilitated extensive distribution networks.
To maintain a steady supply, the Roman state implemented advanced supply chain systems. Provinces paid taxes in olive oil, which was then redistributed to Rome’s population. Archaeological finds, such as the Port Vendres II shipwreck from 40 CE, reveal the complexity of Roman trade, with olive oil transported alongside goods like wine, fish sauce, pottery, and metal ingots from multiple merchants.
"There are two liquids that are especially agreeable to the human body, wine inside and oil outside, both of them the most excellent of all the products of the tree class, but oil an absolute necessity." – Pliny the Elder
Roman expertise in olive cultivation was unmatched. In the 1st century CE, Pliny the Elder documented 22 varieties of olive trees, detailing their cultivation and production methods. Their systematic approach not only fueled economic growth from the 2nd century BCE to the 2nd century CE but also ensured olive oil’s enduring presence in Mediterranean trade, even as the eastern empire continued to thrive.
Olive Oil in Ancient Religion and Society
Olive oil wasn't just an economic powerhouse in the ancient Mediterranean - it held profound spiritual and societal value, deeply woven into the fabric of daily life and religious traditions.
Greek and Roman Social Uses
In ancient Greece, olive oil was much more than a trade commodity; it was sacred. The Greeks believed the olive tree was a divine gift from Athena, elevating olive oil to a symbol of divine favor. It played a central role in religious ceremonies and offerings to the gods. Greek athletes would rub olive oil on their bodies before competitions, an act symbolizing health and purity.
The Romans embraced these traditions and took them a step further. Olive oil was used to anoint priests and sacred objects, integrating it into both religious rituals and daily routines. Romans even replaced soaps with olive oil for cleansing their bodies and used it in medical treatments and perfumes. Remarkably, isotopic studies from Herculaneum reveal that even working-class Romans consumed about 20 liters of olive oil annually.
"There are two liquids that are especially agreeable to the human body, wine inside and oil outside, … but oil is an absolute necessity." - Pliny the Elder
Olive oil also illuminated homes, temples, and public spaces, fueling clay and bronze lamps. These lamps carried more than practical value - they held spiritual meaning, as their flames were often offerings to the gods. The purity of the oil used in such ceremonies was deemed essential. This reverence for olive oil bridged the gap between the mundane and the divine, embedding it in both everyday rituals and sacred traditions.
Biblical References
Olive oil's sanctity extended into biblical traditions as well. In the Old Testament, it was commanded that only olive oil be used to light the Menorah during the Jewish people's exodus from Egypt. Anointing with olive oil was a recurring practice in biblical accounts, used to consecrate kings, priests, and sacred objects. This act symbolized a profound connection between earthly roles and divine authority.
In ancient Egypt, olive oil was reserved for the elite and held spiritual significance. It symbolized luxury and purity, often playing a key role in temple rituals conducted by priests. Its use in these sacred ceremonies underscored its association with sanctity and high status.
These religious and societal practices not only shaped daily life but also fueled the demand for olive oil, driving Mediterranean trade for centuries.

Production Methods and Economic Systems
The ancient Mediterranean world saw groundbreaking developments in olive oil production, turning what was once a basic agricultural process into a highly organized and efficient industry. These advancements, paired with strategic economic policies, propelled olive oil to a central role in ancient trade networks and imperial economies.
Improved Processing and Storage Methods
Between 200 BCE and 200 CE, the Romans transformed olive oil production by scaling up operations and introducing advanced machinery. They developed several types of olive presses, such as the trapetum, mola molearia, canallis et solea, torcular, prelum, and tudicula. These presses utilized lever and counterweight systems to extract oil far more efficiently than earlier methods. The trapetum, in particular, stood out for its ability to crush olives with remarkable precision and speed, setting a new standard for olive oil processing.
Historical records suggest extraordinary production levels during this period. For instance, Tripolitania produced up to 30 million liters annually, while Byzacena reached a staggering 40 million liters. At Monte Testaccio, an artificial hill in Rome composed of discarded amphorae, archaeologists estimate that the city imported about 6.5 billion liters of olive oil over 260 years.
The Romans also revolutionized storage and transport. They used amphorae, which held approximately 39 liters each, for efficient shipping, while large pithoi were ideal for bulk storage. Although modern mills now rely on advanced technologies like hammer breakers and rotary disks to process oil more rapidly, the foundational techniques introduced by the Romans still influence today’s practices.
As Furio Battelini, technical director of Agraria Riva del Garda, aptly noted:
"Without these advancements, we would not have the extraordinarily high quality of our olive oils".
Economic Effects on Ancient Societies
Olive oil was more than just a trade commodity - it became deeply woven into the economic and political fabric of ancient societies. The Romans, for example, integrated olive oil into their taxation and redistribution systems. Emperor Septimius Severus initiated a policy of collecting olive oil as provincial taxes, which was then redistributed to the population of Rome. This approach ensured a steady supply for the capital, strengthened economic ties between provinces, and served as a tool for political support.
Beyond production methods, economic policies played a crucial role in expanding olive oil's reach. From Solon's early export restrictions to the Ottoman Empire's later tariff reductions, policy changes consistently shaped production and trade . A striking example comes from the Ottoman Empire in the 19th century. In 1861, the Ottomans reduced export tariffs on olive oil from 12% to 8%, and by 1869, the rate had dropped to just 1%. These reforms had an immediate and dramatic impact, as shown in the following table:
| Year | Olive Oil Exports (Oqqas) | Value (Piasters) |
|---|---|---|
| 1857 | 20,000 | - |
| 1860 | 2,040,000 | 10,200,000 |
| 1876 | 3,500,000 | 24,500,000 |
| 1879 | 2,000,000 | 10,000,000 |
Between 1857 and 1876, export volumes skyrocketed by 17,400%, demonstrating how favorable policies incentivized production. The Ottoman government also invested in long-term growth by encouraging the planting of 500,000 olive trees annually starting in 1863.
As the Roman Empire expanded, regions like Syria and Cilicia benefited significantly from the growing demand for olive oil. In areas like central Tunisia and western Libya, extensive irrigation systems supported large-scale cultivation. Cato, a Roman writer, documented that some producers managed to achieve annual yields of 50,000 to 100,000 liters from a single operation. These examples underscore how state policies and trade reforms elevated olive oil to a vital economic and political resource in the Mediterranean.
Together, the technological breakthroughs, smart trade strategies, and large-scale production methods of the ancient Mediterranean created an economic system that left a lasting mark on commerce and industry for centuries.

The olive oil industry continues to honor ancient techniques as the foundation for producing high-quality oil. While technological advancements have streamlined production, the time-tested principles that originated in the Mediterranean thousands of years ago still guide today’s producers who focus on quality over volume.
This enduring connection to tradition highlights the reliability and wisdom of methods refined through centuries of practice.
Ancient Techniques in Premium Oil Production
Producers like Big Horn Olive Oil skillfully blend traditional methods with modern technology to create high-quality oils. One of the oldest and most respected techniques, cold pressing, has been used for around 6,000 years and remains the standard for making Ultra Premium Extra Virgin Olive Oil today.
The ancient Romans introduced a grading system for olive oil based on pressing methods. The first-press oils were highly valued for cooking and ceremonial uses, while lower grades were reserved for industrial purposes. This system is mirrored in modern classifications, where Extra Virgin Olive Oil represents the highest quality achieved through mechanical extraction.
Modern cold-extraction methods, which keep temperatures below 80.6°F (27°C), preserve the oil’s natural properties and prevent damage caused by heat. Inspired by ancient stone mills, today’s producers use stainless steel grinders to avoid contamination. The olives are ground into a paste for 30–40 minutes, allowing oil droplets to merge and natural enzymes to develop the rich, complex flavors that define premium olive oil.
As Olive Oil & Beyond explains:
"It's not surprising that the best Extra Virgin Olive Oils today are still made using time-honored traditions that have been passed down from generation to generation." - Olive Oil & Beyond
To ensure the freshest oil, producers often cold-press hand-picked olives within just two hours of harvest. Big Horn Olive Oil, for example, adheres to this standard, echoing the practices of ancient Mediterranean traders who valued freshness and quality.
Storage methods also reflect ancient wisdom. While the Minoans used massive clay jars called pithoi to store olive oil, modern producers rely on stainless steel containers to shield the oil from oxygen and light - two key factors that can degrade its quality.
Olive Oil's Modern Significance
Building on these ancient techniques, today’s producers balance tradition with sustainability. Olive oil’s importance has grown significantly since ancient times, fueled by its recognized health benefits and culinary versatility. Historically, it took about 10–11 pounds of olives to produce a single liter of oil, and in ancient Syria around 2000 BCE, olive oil was valued at five times the price of wine. Modern consumers now enjoy oils that meet the same high standards of flavor, aroma, and quality prized thousands of years ago.
The demand for "Premium Extra Virgin" olive oils - known for their low acidity and superior flavor - has elevated traditional production methods, allowing them to command higher prices and maintain olive oil’s reputation as a luxury item.
The emergence of oleotourism has further strengthened this connection to tradition. Visitors can experience the production of olive oil firsthand, while the growing interest in kilometre-zero products helps support local economies and reduce environmental impact. Companies like Big Horn Olive Oil have embraced this trend by offering Ultra Premium Extra Virgin Olive Oils, celebrated for their high antioxidant content and exceptional quality. Varieties like Estate Reserve, Picual, and Coratina showcase the perfect marriage of ancient practices and modern precision.
Many of the sustainability principles practiced by ancient Mediterranean producers resonate strongly today. Their organic and less invasive methods are increasingly appealing to environmentally conscious consumers.
Chef Karim Arsanios of Solar Olives sums up this sentiment:
"Tradition is so relevant to us... Sure, the design of the product or the technology used to make our extra virgin olive oils might be very advanced, but tradition is the essence of what we do." - Chef Karim Arsanios, Solar Olives
As Stefan & Sons eloquently put it:
"From ancient temples to modern wellness movements, olive oil has remained a vital part of the human story." - Stefan & Sons
