What does 'Appellation d'Origine Contrôlée' (AOC) signify?

'Appellation d'Origine Contrôlée' (AOC) signifies a system in France that designates wines with a controlled designation of origin. This means that the wine must be produced in a specific geographic area and adhere to strict regulations regarding grape varieties, production methods, and quality standards unique to that region. The AOC system is designed to protect the quality and authenticity of regional products, ensuring that consumers can trust the origin and characteristics of the wine they are purchasing. By requiring adherence to these stringent criteria, the AOC helps maintain the traditional practices that define the unique flavors and qualities of wines from that area, making it a vital aspect of France's wine heritage.
