Protected Designation of Origin (DOP)

The official recognition by the European Union (Council Regulation nr 1845/2004, issued on October 22, 2004) (PDF, 48 KB, in Italian) protects the high-quality extra-virgin olive oil in the region of Trieste with a protected origin, named after the ancient name of the city, which is “TERGESTE”.

This is an important achievement following a long process involving numerous institutions, private enterprises, enthusiasts, oil tasters, press owners and many others.
