Dieter Oberg is scientifically involved in the history and quality of olive oil and continues to train intensively, especially in the field of sensory evaluation. In 1998, he co-founded the German Olive Oil Panel (DOP), which he now leads. He is therefore responsible for compliance with quality standards.

He is also a lecturer for olive oil sensory evaluation at the University of Applied Sciences in Zurich and a jury member in various international olive oil competitions such as PremioBIOL (Italy), the International Olive Oil Award (Switzerland) and the tests by the Hamburg magazine Feinschmecker. He is an active member of the olive oil Panel of Berlin GOOA | Global Olive Oil Awards.
