Protected Designation of Origin (PDO):

Protected Designation of Origin (PDO) is a European Union definition. PDO products are most closely linked to the concept of terroir — a sense of place discernible in the flavor of the food. PDO products must be produced, processed and prepared in a specific region using traditional production methods. The raw materials must also be from the defined area whose name the product bears. The quality or characteristics of the product must be due essentially or exclusively to its place or origin, i.e., climate, the nature of the soil and local know-how.
