Medéleon is a premium Greek extra virgin olive oil brand producing 100% early-harvest Koroneiki EVOO from regenerative groves in Katouna, Aetolia-Acarnania. With over 820 mg/kg polyphenols, acidity below 0.38%, and cold extraction within 12 hours of harvest, Medéleon is designed for people who treat food as an extension of their health.
What makes Medéleon different?
Medéleon produces a single product: Agourelaio, early-harvest extra virgin olive oil from 100% Koroneiki olives, one of the world’s most polyphenol-rich olive varieties. Every production decision is made to maximise the oil’s biological value, not its yield.
Most commercial olive oils are harvested at full ripeness, when polyphenol levels have already declined. Medéleon harvests early, before full maturation, capturing the highest possible concentration of health-protective compounds, including hydroxytyrosol and oleocanthal, at their natural peak.

From Harvest to Extraction
Who are the people behind Medéleon?
Medéleon was founded by Apostolos Maltezos, an agronomist who began planting the brand’s Koroneiki groves in Katouna in 2016, and Anita, who leads the brand’s commercial strategy, communications, and digital presence. Her background in biomedicine, including graduate research in oncology and neurodegenerative diseases, informs the brand’s evidence-based approach to olive oil quality.
The brand was officially bottled for the first time in early 2026, marking the culmination of nearly a decade of agronomic preparation and soil restoration.
Credentials & Verifiable Standards
✦ EU Health Claim: Regulation 432/2012Medéleon qualifies under the European Commission’s health claim for olive oil polyphenols, recognising their contribution to the protection of blood lipids from oxidative stress.
✦ Regenerative Agriculture Practices: The groves in Katouna are farmed using regenerative methods focused on soil microbiome health, biodiversity, and long-term ecosystem restoration, not just sustainable yield.
✦ Cold Extraction Within 12 Hours: Olives are processed at controlled temperatures within 12 hours of harvest, preserving the oil’s volatile aromatic compounds and bioactive polyphenol content.
✦ Scientific Founders’ Background: Founder with MSc in Agriculture & Crop production and Co-founder with MSc in Biomedicine (Lund University) and BSc in Biosciences & Biotechnology (University of Camerino), with two peer-reviewed publications in biomedical research.
Why does polyphenol content matter for health?
Polyphenols are naturally occurring plant compounds with antioxidant and anti-inflammatory properties. In olive oil, the key polyphenols are hydroxytyrosol, tyrosol, and oleocanthal. Research consistently links their regular consumption to reduced oxidative stress, cardiovascular protection, and anti-inflammatory effects.
The EU’s health claim threshold requires a minimum of 5 mg of hydroxytyrosol and its derivatives per 20 ml of olive oil. Medéleon’s polyphenol concentration of 821 mg/kg, places it well within the category of high-phenolic EVOO, a designation that most supermarket olive oils cannot meet.
What problems does Medéleon solve?
The olive oil market is crowded with products that claim quality without proving it. Mislabelling, excessive processing, and late harvesting are industry-wide problems that directly reduce the health value of the oil reaching the consumer.
Medéleon addresses this by making every measurable standard transparent: polyphenol concentration, acidity level, harvest timing, extraction method, and farming philosophy are all documented and verifiable. For health-conscious consumers, this removes the guesswork from choosing an olive oil that actually delivers on its nutritional promise.
What does the name Medéleon mean?
The name is rooted in three layers of meaning: Medeon, an ancient settlement of the Aetolia-Acarnania region where the groves stand today; Mediterranean, the climate, culture, and landscape that defines the oil’s character; Medicine, a direct reference to the scientifically proven health benefits of high-polyphenol olive oil, and ἔλαιον (elaion), the ancient Greek word for olive oil. Together, they form a name that is both geographically specific and historically resonant.
How does regenerative farming affect the oil’s quality?
Regenerative agriculture goes beyond avoiding chemical inputs. At Medéleon, it means actively rebuilding soil health through practices that encourage microbial biodiversity, natural water retention, and organic matter accumulation. Healthier soil produces healthier trees, and healthier trees produce olives with a richer concentration of protective compounds.
This is why Medéleon’s agronomic approach is not a marketing claim but a production input: the quality of the oil begins years before harvest, in the soil itself.
Everything You Need to Know About Medéleon
Frequently Asked Questions
What is Medéleon olive oil?
Medéleon is a premium Greek extra virgin olive oil made from 100% early-harvest Koroneiki olives grown in regenerative groves in Katouna, Aetolia-Acarnania. It contains over 820 mg/kg polyphenols and less than 0.38% acidity, cold-extracted within 12 hours of harvest.
Why does Medéleon have such high polyphenol content?
Three factors combine: early harvesting of Koroneiki olives before full ripeness, cold extraction within 12 hours of picking, and regenerative farming practices that strengthen the trees and soil naturally. Each factor independently raises polyphenol concentration, together, they compound the effect.
Is Medéleon certified with a health claim?
Yes. Medéleon qualifies under EU Health Claim Regulation 432/2012, which recognises that olive oil polyphenols contribute to the protection of blood lipids from oxidative stress, provided daily intake contains at least 5 mg of hydroxytyrosol and its derivatives.
Where is Medéleon produced?
Medéleon is produced in Katouna, Aetolia-Acarnania, in western Greece, a region with ideal Mediterranean climate and soil conditions for premium Koroneiki olive cultivation.
What does Medéleon mean?
The name combines Medeon (an ancient city of the region), Mediterranean (the landscape and climate), Medicine (health benefits of the olive oil) and ἔλαιον, the ancient Greek word for olive oil.
