A gran cru (French for great growth) is a regional wine classification that designates a vineyard known for its favorable reputation in producing wine. It is not a classification of wine quality per se, but rather the potential of the site or terroir. It is the highest level of classification of AOC wines from Burgundy or Alsace. The same term is used in Saint-Émilion and Champagne, but there it refers to a differing level of classification. In Burgundy the level following Grand cru is known as premier cru.
