What percentage of wine in Chile must come from the stated region, vintage, and grape to be included on the label?

In Chile, for a wine to be labeled with a specific region, vintage, and grape variety, at least 75% of the wine must come from the specified criteria. This percentage ensures a level of authenticity and quality, as it requires a significant majority of the wine to match what is being claimed on the label. This regulation helps consumers trust that they are getting the characteristics associated with the particular region, year, and grape type they are purchasing. The 75% requirement is a balanced approach that supports both producers' marketing efforts and consumer confidence.
