DOCG stands for "Denominazione di Origine Controllata e Garantita," which is an Italian quality assurance label for wines. It signifies that a wine meets strict production standards, including specific grape varieties, geographical origin, and winemaking techniques. This designation is intended to protect the reputation of high-quality Italian wines. To receive the DOCG label, wines must undergo rigorous testing and approval by government authorities. This ensures that consumers can trust the quality and authenticity of the wine they are purchasing. Notable examples of DOCG wines include Barolo, Brunello di Montalcino, and Chianti Classico.
