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.

Michelle, born in 1997, graduated in Business Administration in the University of Studies in Torino.

Currently she has been working in the family olive oil mill, F.lli Ruata S.p.a., in Baldissero d’Alba (Cuneo, Piedmont).

I was born in Japan but have lived in several countries, including Italy for 16 years, where I undertook a course of study.

I began my professional career as an Export Manager for Mitsubishi Italia S.p.A. in the food industry, developing a passion for good food with a focus on olive oil, which soon became my main occupation. Since returning to Japan, I have been working as a Purchasing Manager for a major company specializing in cheese imports

In 2016, I commenced my training with ONAOO, which concluded in 2022 with my designation as a Professional Taster. I intend to pursue this interest further.

Tomaso, after extensive experience in various companies as a Manager and Executive, and now as a consultant, driven by curiosity and a strong passion for this wonderful product, olive oil, decided to undertake a training program aimed at deepening his knowledge and refining his tasting technique. To do this, he turned to the world’s leading and most prestigious school of sensory analysis, the ONAOO. He initially enrolled in the Official Technical Course and obtained the Certificate of Physiological Suitability for Tasting in May 2018.
