"The world of the olive oil and its supply chain also offers a wide range of job, growth and specialization opportunities."

In the food industry, in fact, olive oil is the only product for which sensory analysis is legally valid and, therefore, there is an increasing request for selected tasters – Panels trained to objectively assess the sensory characteristics of this product.

Since 1983, O.N.A.O.O. is the first school in the world teaching the art of olive oil tasting and it trains new tasters for this purpose, providing the most up-to-date scientific knowledge in every educational field. The trainers, who are qualified and accredited professionals, share with the participants their solid knowledge. Only here, the participants in the courses can learn about and taste oils from all over the world.

The O.N.A.O.O. official technical course was created with this goal in mind. The course, which lasts at least 35 hours, is led by a responsible Panel Leader and recognized by the Ministry of Agriculture and authorized by the Region where the course is held.

Participants who pass the four selective trials receive a Certificate of Physiological Eligibility for Tasting; in case of failing, a Certificate of Participation in the course is still issued.
