A PDO product has to be wholly produced, processed and prepared in a given geographical area and in compliance with the strict production rules set out in the product regulations.
Which is why a PDO product, the guaranteed result of so many natural (raw materials, production area, climate etc.) and human (production and processing techniques) factors, is truly unique and could not come from anywhere else.
From farming standards on managing olive groves, to harvesting and packaging, all the PDO regulations have to be strictly observed to obtain the coveted European quality certification.
And checks continue after packaging, through sales and marketing to ensure absolute compliance of the product with the standards required.
