D.O. (Denomination of Origin)

D.O. (Denomination of Origin) is a certification that indicates a product, like wine, cheese, or olive oil, is produced in a specific geographic region using traditional methods unique to that area. It ensures the product's quality, authenticity, and connection to its location’s natural conditions and cultural practices. For example, Champagne can only come from the Champagne region in France. This designation helps protect regional identity, maintains standards, and assures consumers they are getting an authentic product rooted in its local origin.
