The French term means "great plant", usually refers to wine (but also to other foods such as beer, coffee and chocolate) and is closely related to the French philosophy of the terroir. This means that regardless of the possible variations in quality between individual vintages, a certain type of soil and the climate there (microclimate) are of constant and determining quality. The Cru Classés are to be understood in addition to the Appellation d'Origine Protégée, which is valid in France, and characterize the top qualities. However, the term has a different meaning in the individual wine-growing regions. It can refer to a site, a municipality or a château (winery) or to the wine produced there. In Bordeaux, the interests of the Grands Crus vineyards are represented by the UGCB (Union des Grands Crus de Bordeaux).
