The French term means "great growth", usually refers to wine (but also to other foods such as beer, coffee and chocolate) and is closely linked to the philosophy of terroir. This means that, regardless of possible fluctuations in quality between vintages, a certain type of soil and the local microclimate are of consistent and determining quality, whereby the art of the winegrower is also decisive.
The Cru Classés are to be understood in addition to the Appellation d'Origine Protégée valid in France and characterise the top qualities. However, the term has different meanings in the individual wine-growing regions. It can refer to a location, a municipality or a château (vineyard) or to the wine produced there. In Bordeaux, the interests of the Grands Crus wine estates are represented by the UGCB (Union des Grands Crus de Bordeaux).
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
