An "appellation" is a legally defined and protected geographical name used to identify where a particular product, especially food and wine, originates. This term is most commonly associated with wine, where regions like Bordeaux or Champagne signify specific qualities and characteristics tied to their location. Appellations help consumers understand the origin and quality of the product they are purchasing. In many countries, appellations are regulated by law to ensure that products meet certain standards. For example, in France, the Appellation d'Origine Contrôlée (AOC) system governs the production of wine and cheese, ensuring that only products from designated areas can use specific names. This system helps maintain the integrity and reputation of regional products.
