Tomaso, originally from Vicenza, worked for many years in the marketing sector of an important machine manufacturer.

Driven by curiosity and a strong passion for this wonderful product, olive oil, Tomaso decides to undertake a training course aimed at deepening his knowledge and refining the tasting technique: for this reason he becomes aware of the First School in the world of sensory analysis, the ONAOO. He first enrolled in the Official Technical Course and obtained the Certificate of Physiological Suitability for Tasting in May 2018.

More and more fascinated and willing to learn, he enrolled in the Advanced Course: after two years of study aimed at deepening the tasting technique, in June 2021 he passed the exam and thus obtained the qualification of ONAOO Professional Taster.

Tomaso also regularly attends the activities organized by the ONAOO School and is also enrolled in the National List of Technicians and Experts in virgin and extra virgin olive oils.

Özerson Duygu Elakdar

I was born in Ankara in 1978. After graduating from the Faculty of Political Sciences of the University of Ankara, I graduated in Marketing from the Sorbonne University.

After working for many years in the fashion sector in Paris, I decided to return to Turkey and to settle in Urla (Smyrna) in 2011, where I got married and had 2 children.

With the aim of producing the best olive oil in Urla, I started my training at ONAOO (Italy). After 5 years of training, I obtained the qualification of Professional Taster, and I launched my brand “Hiç Extra Virgin Olive Oil”. “Hiç Edible Olive Forest” is the place where my family and I produce olive oil and it is made up of 60,000 olive trees; this olive grove is the center of our holistic approach where nature, sustainable agriculture and gastronomy meet.

In 2018 we opened our restaurant, “Hiç Lokanta ve Tadım Atölyesi” (restaurant and tasting laboratory), where we emphasize all this diversity, the seasonality of nature’s treasures with New Urla Cuisine.

Now the “Hiç” brand has become a gastronomy and agricultural tourism platform with the Hiç olive grove in the center.
