PROFILO:

Born in Istanbul and graduated from Boğaziçi University in 2008. My journey in olive oil sector began during my professional career as a Brand Manager at one of Türkiye’s most established and respected olive oil brands. What started as a professional responsibility quickly transformed into a deep personal passion for olive oil and its cultural significance. This long-term professional exposure and knowledge of the entire value chain combined with a growing personal dedication to learning and tasting, ultimately led me to pursue formal training and certification with ONAOO.

I am currently working as a brand consultant mainly working with olive oil brands. Besides, I am olive oil panel member of Ayvalık Chamber of Commerce.

Leonidas Komvokis

Leonidas Komvokis is a resident and business owner in Drama, East Macedonia and Thrace.

He is an agricultural and olive entrepreneur. He is an olive pruner and has participated in several professional olive pruning courses organized by the A.S.S.A.M. School (Marche). In 2016, Leonidas became a member of ONAOO, where he began his training. In January 2020, he completed his studies by obtaining the Professional Taster Qualification.

Leonidas believes that a deep understanding of the elements of olive oil quality is an effective way forward in the field of olive growing and entrepreneurship. He provides olive oil quality consulting services as well as olive tree pruning and management services on a contract basis. In recent years, the company has focused on developing a project with the planting of 20 hectares of organic olive trees and varieties exclusively indigenous to the area.

The goal is to highlight these varieties and create monovarietal oils of unique quality, showcasing the quality characteristics of the area and the POLYCONIC VASE-shaped management model that can guarantee the highest quality of olive oil. Quality is a core value that guides our commitment to the environment, consumers, and the reputation of our organization, which is represented by the ONAOO.

Through my company Oliiv, I import, introduce, and sell high-quality extra virgin olive oil in Estonia, primarily through an online store and curated experiences. The website and e-shop provide the opportunity to learn more about each product and make informed purchases.

My activities include guided tastings, culinary pairings, and cultural events — from intimate gatherings at home to market events and musical evenings with olive-oil-based cocktails. The goal is always to spark curiosity and offer enjoyable and educational experiences centered on olive oil.

In a country where butter dominates the cuisine, there is great potential to show how olive oil can be part of a healthy, joyful Mediterranean lifestyle. For this reason, collaboration with chefs and cooking schools is becoming an important part of my work.

Looking ahead, I am particularly interested in engaging with the international olive oil community. Participating in global competitions — both as a taster and as a judge — is one of my aspirations. It is a valuable way to continue learning, contribute to quality standards, and bring new ideas and energy to the Estonian market.

We venture into the culinary world not just for taste, but also for culture. It means experiencing a moment of insight, a flash of memory, or understanding a tradition, a civilization. — Umberto Eco

Started technical course in 2023, and graduated in 2025 November in Imperia.

Olive oil is a passion and a profession for me and I look forward to contributing to the global olive oil community.
