The term "Denominación de Origen" (DO) refers to a designation used to identify products that originate from a specific geographical area, where the quality and characteristics are closely linked to that location. This system is commonly applied to food and beverages, such as wine, cheese, and olive oil, ensuring that they meet certain standards and are produced using traditional methods. In many countries, including Spain and France, the DO system helps protect local producers and promotes regional specialties. It also provides consumers with assurance about the authenticity and quality of the products they purchase, fostering appreciation for traditional craftsmanship and local heritage.
