Roberto Rastrelli is a Professional Taster of ONAOO since 1989.

Born in a country where butter is king and mayonnaise is queen, I was pleasantly surprised by the magnificent taste and pleasantness of extra virgin olive oil during my holidays in south east Crete in the 80s.

At the time, I was working in the product engineering sector in a multinational company, but I was ready for a change.

I started importing this delicious product and I set myself the challenge of letting the people who love butter in my country taste this gift of nature. As a pilot, I knew it was possible to fly without an engine, but not without knowledge and skills. I quickly realized that additional support was needed to achieve my goals.

So I knocked on ONAOO’s door. Thanks to the dedication of the teachers, I embarked on a fascinating 3-year learning path.

I enjoyed developing my skills and knowledge and thanks to this support I have seen my business grow. Through retail, restaurant, direct sales and the web shop, I distribute two superb brands of extra-virgin olive oil, one Greek and one Spanish. “Olijfwinkel.be” is my starting point, alongside my company “Techtel.be”.

Osman, who is passionate about olives and olive oil, grew up in Izmir, one of the major olive producing regions of Turkey.

After two years of training, he obtained the qualification of Professional Taster of ONAOO in 2023. He provides consultancy to farmers and olive oil producers in Turkey and product experience in Switzerland.
