Stig has been Senior Brand Manager at Haugen-Gruppen AS, the largest food import company in Norway.

He has worked in the food sector for more than 25 years, in companies such as Nestlé, Mars, and Haugen-Gruppen AS. He started working with olive oil in 2000 when he joined Haugen-Gruppen as a Key Account Manager. He sold olive oil to the main retail chains in Norway. 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 taken part in many olive harvests and presses in Spain, Italy and Greece in the last 12 years to get to know the different “cultures” of olive oil production (from small producers to large ones) and to understand the differences. 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.

In 2018, Wilma finished her training at the ONAOO. She was in charge of buying Mediterranean products, including olive oil. Being Dutch, she didn’t know much about olive oil and found a school in Italy.

She loved it so much that she left her job and started working in the olive oil business. She also trained as a sommelier in New York and a master miller in Jaen. She asked the Ministry to appoint her as panel leader at the European Union. She wrote the book “Olive Oil,” which has been translated into English, French, and German.

Her book encourages olive oil lovers to meet in Imperia. O.N.A.O. is a big family! He also founded the Olive Oil Institute, which has a panel of fifteen members, most of whom were trained by O.N.A.O.O. The Institute has an electronic nose, so that testing can be done objectively. Some universities are also trying a similar method. This should improve quality overall. But the panel will always exist because human judgment is needed.

CEO & Co-Founder The O Collection

I began the ONAOO tasting course initially in March 2023. After passing the first stage, I then transitioned into the two-year advanced course in October 2023, and completed the course in November 2025.

Olive oil is far more than a food – it’s a world of culture, community, science, and craftsmanship. I’m grateful to be part of this journey of discovery, deepening my understanding, and sharing that knowledge with others.

Since 2017, she’s been a professional olive oil taster for ONAOO. She’s also an olive oil and wine sommelier, a passionate foodie, and an avid traveler. Liana is a former lawyer who has been in the food import business for 12 years.

She started her company, ITALISKO SKONIO GURMANAI Ltd., in Italy, focusing on extra virgin olive oil. She also opened three specialised Italian gourmet stores and an e-commerce store in Lithuania. Ten years ago, she set up the first olive oil school in Lithuania. She also puts on events, courses, tastings, and tasting dinners, as well as promoting olive oil culture.

She represents more than 25 quality olive oil producers from the world’s best ranking in Lithuania. Liana and her company ITALISKO SKONIO GURMANAI Ltd. were absolutely thrilled to be awarded by International olive oil guide Flos Olei as the best Importer in the world of the year 2016!
