French for "great growth," Grand Cru is the highest possible ranking for a vineyard or village in certain winegrowing regions of France, particularly Burgundy and Alsace. It's sometimes referred to as Grand Cru Classé́s, which includes all of the 61 cru-class wineries in Bordeaux Mé́doc. For a more detailed explanation of this arcane and bewildering form of winery hierarchy, see cru.
