The History of Olive Oil in Greece (From Ancient Times to Today)

If you were to take a walk through the ruins of Knossos in Crete or wander the ancient pathways of the Acropolis in Athens, you would find the ghosts of the past whispering one common secret: the olive tree.

It is impossible to separate the history of Greece from the history of the olive. For over four millennia, this sacred fruit has been the heartbeat of the region. It has fed nations, fueled lamps, anointed kings, and healed the sick. In Greece, olive oil was never just a food product; it was a divine gift, a currency, and a symbol of civilization itself.

Today, science is finally catching up to what the ancient Greeks knew intuitively—that olive oil is one of nature’s most potent medicines. But to truly appreciate the bottle of "liquid gold" sitting in your kitchen, you must understand the journey it took to get there.

In this exploration, we will travel back through the mists of time, from the Neolithic era to the bustling modern groves of the Peloponnese, to uncover the rich, complex, and fascinating history of olive oil in Greece.

 

The Mythological Roots: A Gift from the Gods

Before there was history, there was myth. The ancient Greeks used storytelling to explain the world around them, and the origin of the olive tree is one of their most famous tales.

The Contest for Athens

The legend goes that the city of Athens, then just a small settlement, was looking for a patron deity. Two powerful Olympian gods vied for the honor: Poseidon, the god of the sea, and Athena, the goddess of wisdom and war.

To settle the dispute, Zeus decided that each god would offer a gift to the citizens of the city. The people would then choose which gift was more valuable.

• Poseidon struck the rock of the Acropolis with his trident. A spring of salt water gushed forth. It represented naval power and command of the seas—a mighty gift, but the water was salty and undrinkable.

• Athena knelt and planted a seed in the ground. Within moments, a magnificent tree sprouted with silver-green leaves and abundant fruit. It was the first olive tree.

The citizens chose Athena’s gift. They recognized that the tree offered wood for building, shade for resting, and most importantly, oil for food and light. The city was named Athens in her honor, and the olive tree became the symbol of the city—representing peace, prosperity, and sustenance.

This myth highlights a fundamental truth: for the Greeks, the olive tree represented life itself. It was the difference between survival and starvation.

 

The Minoans: The First Olive Oil Economy

While myths set the cultural stage, archeology gives us the facts. The true history of systematic olive cultivation begins on the island of Crete with the Minoan civilization (c. 3000–1100 BC).

The "Liquid Gold" of Crete

The Minoans were an advanced, seafaring people, and they were the first to turn olive oil into a major industry. Archeological excavations at the Palace of Knossos have revealed giant clay jars, known as pithoi, used for storing vast quantities of oil. Some of these jars were tall enough to fit a grown man inside.

• Economic Power: Olive oil was the backbone of the Minoan economy. They didn't just consume it; they exported it across the Mediterranean to Egypt and the Levant.

• Culinary Use: It was the primary fat source in their diet, laying the groundwork for what we now call the Mediterranean Diet.

• Industrial Use: It was used to make perfumes and medicines, adding herbs and spices to the oil to create valuable commodities.

The wealth of the Minoan civilization was literally built on olive oil. It is no coincidence that Crete remains one of the premier olive oil-producing regions in the world today. The DNA of those ancient groves still exists in the modern trees. You can read more about how we source our oil from these historic regions on our Our Story page.

 

The Golden Age: Olive Oil in Classical Greece

As power shifted from Crete to the Greek mainland, the importance of olive oil only grew. During the Classical period (c. 5th and 4th centuries BC), the olive tree was protected by law.

Solon’s Laws

Solon, the famous Athenian lawmaker, introduced legislation in the 6th century BC that prohibited the cutting down of olive trees. The penalty for destroying a tree could be death or exile. This demonstrates how critical the crop was to the survival of the state. Solon also encouraged the export of olive oil, recognizing it as Athens' only significant agricultural surplus.

The Panathenaic Games

Athletics and olive oil were deeply intertwined. In the ancient Olympic Games and the Panathenaic Games held in Athens, athletes competed naked, their bodies glistening with olive oil.

• Muscle Warm-up: The oil was believed to warm the muscles and protect the skin from the sun and dust.

• The Prize: Winners of the Panathenaic Games were not given medals or money. They were awarded large, beautifully decorated ceramic vases (amphorae) filled with the finest sacred olive oil from the groves of Athena. To win such a prize was to win a fortune.

Hippocrates and Medicine

It was during this era that Hippocrates, the father of modern medicine, began to document the therapeutic properties of olive oil. He called it "the great healer."

• Treatments: He prescribed it for over 60 different conditions, including skin diseases, wounds, burns, and gynecological issues.

• Hygiene: Before soap was invented, Greeks cleaned themselves by slathering their bodies in oil and then scraping it off (along with dirt and sweat) using a metal tool called a strigil.

This ancient medicinal use parallels our modern understanding of olive oil's anti-inflammatory and antibacterial properties. The Greeks didn't know about polyphenols or oleocanthal, but they saw the results.

 

The Roman Era and Byzantine Continuation

When the Romans conquered Greece, they didn't destroy the olive culture; they absorbed and expanded it. The Romans were obsessed with Greek culture, and they adopted the Greek love for olive oil enthusiastically.

Technological Advancements

The Romans were master engineers. They improved the technology used to press olives.

• The Trapetum: They invented a rotary mill called the trapetum, which used two convex stones rotating in a mortar to crush the olives without breaking the pits (which makes the oil bitter).

• The Screw Press: They also refined the screw press, allowing for much higher pressure and more efficient oil extraction.

Despite these advancements, the heart of the industry remained in Greece. The Greek territories continued to be major suppliers for the Roman Empire.

The Light of Byzantium

As the Roman Empire transitioned into the Byzantine Empire, Christianity took root. The olive tree found new significance in the rituals of the Orthodox Church.

• The Oil Lamp: Olive oil fueled the lamps that illuminated icons and churches. To this day, in Greek Orthodox homes, a small oil lamp (kandili) often burns in front of the family icon.

• Sacraments: Olive oil is essential for the sacrament of Baptism. The baby is anointed with oil, symbolizing the Holy Spirit and protection against evil.

During the Byzantine years, monasteries became major centers of olive cultivation. Monks tended vast groves, preserving agricultural knowledge through times of turmoil and war.

 

Ottoman Rule and the Survival of Tradition

During the centuries of Ottoman occupation (15th to 19th century), life for the Greeks changed dramatically, but the olive harvest remained a constant.

The Ottomans recognized the economic value of the oil and taxed it heavily. Despite the hardship, Greek families clung to their land. The olive tree became a symbol of resilience and resistance. A family might lose their wealth, but as long as they had their trees, they had food and a means of barter.

It was during this period that soap making became a major industry in areas like Crete and Lesvos. Olive oil soap was exported to Europe and the Middle East, prized for its purity and gentleness on the skin.

 

The Modern Era: A Renaissance of Quality

After the Greek War of Independence in 1821, Greece began to rebuild. The olive oil industry remained traditional and fragmented for many years, with local farmers producing oil primarily for their own consumption and selling the surplus in bulk.

However, the late 20th and early 21st centuries have seen a massive shift—a Renaissance of Greek olive oil.

From Bulk to Brand

For decades, a dirty secret of the olive oil industry was that much of Italy's famous oil was actually Greek. Italian merchants would buy high-quality Greek oil in bulk, blend it with other oils, and bottle it as "Italian."

• The Shift: In recent years, Greek producers have reclaimed their heritage. There has been a massive push to bottle and brand Greek oil within Greece, keeping the value in the country.

• PDO Status: The European Union introduced the Protected Designation of Origin (PDO) system. This gave Greek regions like Kalamata, Sitia, and Kolymvari legal protection for their names. It ensured that oil labeled "Kalamata" had to be produced in Kalamata using traditional methods.

The Rise of the Koroneiki

Modern agriculture also saw the solidification of the Koroneiki variety as the "King of Greek Olives." While dozens of varieties exist, the Koroneiki proved to be the perfect balance of resilience and quality. It thrives in the rocky, dry Greek terrain and produces oil with exceptionally high levels of polyphenols.

This focus on the specific variety allowed Greek producers to market their oil not just as a cooking fat, but as a premium health product. To learn more about our approach and connection to these innovations, visit our Our Story page.

 

The Science of "Liquid Gold"

The most exciting chapter in the history of Greek olive oil is happening right now. It is the era of scientific validation.

For thousands of years, Greeks claimed their oil was medicine. Now, modern science proves it. Researchers have isolated compounds like oleocanthal and oleacein—powerful antioxidants found in high concentrations in Greek Extra Virgin Olive Oil.

• Anti-Inflammatory: Oleocanthal has been shown to work similarly to ibuprofen, reducing inflammation in the body.

• Heart Health: Studies have consistently linked high-phenolic olive oil consumption to reduced risks of cardiovascular disease and stroke.

• Neuroprotection: Emerging research suggests these compounds may help protect against neurodegenerative diseases like Alzheimer's.

This scientific revolution has transformed the way Greek farmers work. They now harvest earlier in the season (early harvest or agoureleo), sacrificing quantity for higher polyphenol content. They use cold extraction methods to preserve the delicate nutrients. The ancient wisdom of Hippocrates has been vindicated by the microscope.

Why the History Matters to You

Why does knowing the history of Minoan jars or Solon’s laws matter when you are buying a supplement or a bottle of oil today?

It matters because provenance is a promise.

When you consume Greek olive oil, you aren't just eating a processed fat manufactured in a factory. You are partaking in a continuous chain of agricultural craftsmanship that has remained unbroken for 4,000 years.

1. Stewardship: The farmers tending the trees today are often working the same land their ancestors worked centuries ago. They treat the trees with a respect that industrial farming cannot replicate.

2. Purity: The history of small-scale, family farming in Greece has protected the country from the super-high-density, chemically intensive farming methods seen elsewhere.

3. Taste: The flavor profile of Greek oil—peppery, grassy, complex—is the taste of history. It is the taste of a tree that has struggled through rocky soil and hot sun to produce a fruit packed with survival nutrients.

 

The Ritual of Harvest: Then and Now

To truly understand the continuity of history, one only needs to witness a harvest. While technology has introduced handheld shakers and modern presses, the essence of the harvest remains a communal ritual.

In late autumn, the Greek countryside comes alive. Families gather. Schools sometimes close in rural areas so children can help their parents. Nets are spread under the silver-green canopy.

• The Beating: Just as in ancient vase paintings, poles are used (now often vibrating ones) to dislodge the fruit.

• The Gathering: The olives are collected by hand from the nets, leaves and twigs removed.

• The Pressing: The sacks are taken immediately to the communal mill. The smell of fresh oil fills the air of every village.

This is not a corporate operation; it is a social one. It is a time of hard work, but also of celebration, food, and connection. This human element is the secret ingredient in Greek olive oil. It is made with love and pride.
