Geographical indications have long been associated with the concept of "terroir" and with Europe as an entity, where there is a tradition of associating certain food products with particular regions. Under European Union Law, the protected designation of origin framework which came into effect in 1992 regulates the following systems of geographical indications: "Protected designation of origin" (PDO), "protected geographical indication" (PGI), and Traditional Specialities Guaranteed" (TSG).
