What is PGI, IGP and DOP?

So what is IGP, PGI and DOP. I have below tried to explain what each of these terms stand for in little more details.

PGI

PGI stands for Protected Geographical Indication. Which is the there to assure that the status of a product is assigned only to selected products obtained according to traditional methods and in specific geographical areas.
That means that the product has a guarantee that the quality and authenticity.

Italian Certifications

IGP 

Indicazione Geografica Protetta (Indication of Geographic Protection)

The IGP label shows that the quality or reputation of your food or condiment is linked to the place or region where it is produced, processed, or prepared.

So PGI and IGP is the same it is just the Italian version of it.

DOP 

Denominazione d’Origine Protetta | Protected Designation of Origin

The DOP label guarantees that your favorite cheese, prosciutto, olive oil, etc., is produced, processed, and packaged in a specific geographical zone and according to tradition. Each step, from production to packaging, is regulated.
