Wine
Certain AOCs for wine are recognized as being superior to others. Typically these are variations on "cru," the French word for growth. Wines called "Grand Cru" are at the top of the quality hierarchy, with "premieres crus" one level below. Beneath these are simple named places. Depending on the region, a cru might be assigned to an estate or to a legally-defined vineyard area. While in theory a Grand Cru should be the finest expression of its site, it is generally a more accurate indicator of price than quality.
