Controlled designation of origin (CDO) is a legal term used to protect and promote the unique identity and quality of agricultural products, food, and beverages that are produced in a specific geographical region. This designation ensures that only products that meet strict production criteria and are made using traditional methods can bear the name of the region on their label. CDO not only guarantees the authenticity and origin of a product, but it also helps to preserve the cultural and historical heritage of a region. This designation is highly valued by consumers as it provides assurance of the product’s quality and distinct characteristics, making it a mark of excellence in the world of gastronomy.
