Protected Designation of Origin is a geographical indication defined in European Union law intended to protect culturally or regionally significant agricultural products and foods. While the designation is linked principally to location, it also recognises the importance of other factors, such as manufacturing techniques and ingredients.
It applies to wines, although typically each European country has its own way of labelling (for example, France’s Appellation d’Origine Contrôlée) which tends to be used in preference.
