In 2019, Diana and her husband initiated the establishment of a modest olive grove in the Marche region of Italy.

As a result of the substantial increase in production, they made the decision to sell their business in the Netherlands. Currently, the company’s exclusive focus is on the production of extra virgin olive oil in Italy under the Di Lorenzetto brand, which is renowned for its superior quality.

To further refine the quality of their oil and gain a deeper understanding of the varieties, flavors, health properties, and defects of olive oil, Diana decided to embark on a training course. She began with a tasting course in Madrid, followed by a technical course and an advanced one at O.N.A.O.O., concluding her studies in november 2024 with the qualification of Professional Taster. In 2024, she also obtained her olive oil sommelier certification at the International Culinary Institute in New York.

Since 2019, Diana has been a member of the Olive Oil Institute panel from the Netherlands. She also regularly conducts workshops and masterclasses for schools, chefs, amateur cooks, and olive oil enthusiasts in the Netherlands and Italy.

Demetris Taliotis is the Chief Olive Oil Obsessive at Aparthenasa, an award-winning agrocraft estate focusing on the production of terroir-driven extra virgin olive oil from Cyprus. He is a graduate of the prestigious Expert Course in Virgin Olive Oil Tasting of the University of Jaén and a jury member to numerous international olive oil competitions. His varied involvement with olive oil spans a multifarious career in agri-food and FMCG marketing, location and countryside management, and expansive research interests at the cross-sections of transversal agriculture, disruptive innovation, organoleptic variability and the cultural and creative industries.

Demetris firmly believes in the de-commodification of micro-produced olive oil, through the exploration and promotion of the variety and variability of its organoleptic profiles, in a way that enhances the sensorial pleasures consumers can relish from Extra Virgin Olive Oil.

I completed my professional training with ONAOO (Organizzazione Nazionale Assaggiatori Olio di Oliva), having had a truly positive and enriching experience. The program deepened my expertise in sensory analysis, olive varieties, production standards, and quality evaluation, strengthening my ability to identify and appreciate high-quality extra virgin olive oil with precision.

Thank you so much to everyone for such a wonderful journey from the bottom of my heart.
