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.

Professional Taster since 2024

Since 2020, she has been cultivating an olive grove in Puglia using entirely natural methods.
Using the expertise she has learned from local farmers and consolidated through her training at O.N.A.O.O., she covers the entire production chain — from land maintenance and pruning to harvesting, pressing, packaging and exporting — all carried out according to best practices.
In Switzerland, she offers her professional expertise to innovative companies in the olive oil industry, organises tastings and workshops.

She is involved in the fight against Xylella, a devastating disease affecting olive trees (https://www.tvsvizzera.it/tvs/qui-italia/quegli-svizzeri-e-quelle-svizzere-impegnati-nella-lotta-contro-la-xylella/78291581).

I started studying tasting related to olive oil, one of the subjects I worked in 2010, and got the title of Professional Olive Oil Taster at ONAOO, the first international school in Italy and number one in the world. I am still continuing my education. I have organized olive oil tasting trainings with ONAOO, workshops and at the world’s most famous capital cities (Paris, Roma, Barcelona, Amsterdam, Morocco, Tunisia and Istanbul).
