Van Grinsven-Padberg Wilma

I completed my training in O.N.A.O.O. in 2018. Through my work as purchasing director of Mediterranean products, I was also responsible for the olive oil category. Being Dutch, I knew very little about it and luckily I found the training in Imperia and I can safely say it changed my life.

After 12 years I quit my job as purchasing director and continued in the world of olive oil. By now I had also done the Sommelier training in New York as well as the Master Miller training in Jaen, Enough baggage to ask the Ministry to nominate me as a panel leader at the European Union.

In between, I wrote the book “Olive Oil” and this has been translated into English, French and German and still my book brings olive oil lovers the idea to follow in my footsteps and we will meet again in Imperia. O.N.A.O.O. is one big family! Meanwhile, I founded the Olive Oil Institute and the Netherlands has an IOC certified panel consisting of 15 panel members, most of them trained by O.N.A.O.O.

In addition to a panel, the Olive Oil Institute has an electronic nose so that tests can be done not only subjectively but also objectively.

Several universities are also looking for such a method and we expect that this combination will improve quality overall. However, the panel will always exist because how good is good or how bad is bad, that remains a human judgment.
