A term mainly used in Bordeaux (also known as Vin de garde) for the best quality and most representative wine of a château. It is subject to particularly strict vinification rules such as yield reduction and ageing. It is pressed from the best grapes and blended from the best wines when blended. Only the Grand Vin is allowed to bear the Château name exclusively on the label. The reason for this is that this is often associated with a vineyard classification. The lesser wines result in the second wine (or third wine), which has a fundamentally different name, or a wine named after the respective appellation. See also under Cuvée de Prestige (top product of a champagne house), Tête de cuvée (among others top wine or vineyard) as well as a list of all classification systems under Grand Cru.
