PDO Wine stands for "Protected Designation of Origin" wine, a classification that ensures the wine comes from a specific region known for its unique characteristics. This designation guarantees that the grapes used in the wine are grown and produced according to strict regulations, preserving the traditional methods and quality of the region. The European Union established the PDO system to protect the reputation of regional products and promote their authenticity. Wines labeled as PDO must meet specific criteria, including grape variety, production methods, and geographical boundaries, ensuring that consumers receive a product that reflects the heritage and quality of its origin.
