PGI stands for Protected Geographical Indication and refers to a certification given to agricultural products or foodstuffs that have a specific geographical origin and possess qualities or a reputation that are linked to that origin. This certification ensures that the product is produced, processed, and prepared in a specific region using traditional methods, resulting in a unique and high-quality product. PGI not only protects the name and reputation of the product, but also supports the local economy and promotes sustainable farming practices. Examples of PGI products include Parmigiano Reggiano cheese from Italy and Champagne from France.
