Wine labeling refers to the information presented on a wine bottle's label, which provides essential details about the wine inside. This includes the wine type, vintage (the year the grapes were harvested), and the winery or producer's name. Labels may also indicate the region where the grapes were grown, which can influence the wine's flavor profile. In addition to basic information, wine labels often feature classifications such as Appellation d'Origine Contrôlée (AOC) in France or Denominación de Origen (DO) in Spain. These classifications help consumers understand the quality and characteristics of the wine, guiding their purchasing decisions.
