Appellations d'Origine Contrôlée (AOC) is a French certification that ensures the quality and authenticity of regional products, particularly in the food and wine sectors. Established in the 1930s, the AOC system protects the unique characteristics of products by regulating their production methods, geographical origin, and specific ingredients. To receive AOC status, producers must adhere to strict guidelines that define how their products are made. This system helps consumers identify high-quality items and supports local economies by promoting traditional practices. AOC is particularly well-known for its association with French wine, cheese, and other regional specialties.
