PROFILO:

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.
