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.

For 15 years he has been a brand manager in the retail sector.

For 3 years he has been a brand manager in the food service sector. In 2015, he took a technical course for olive oil tasters and started training to become a professional taster. He has participated in international meetings for “ONAOO tasters” since 2017.

He has been teaching Norwegians about olive oil by tasting it with managers of big companies, shop managers, journalists, salespeople, and others. He now runs his own company, Lukt, Smak og Nyt (Smell, Taste and Enjoy), teaching consumers how to select and use extra virgin olive oil.
