Saint-Émilion Grand Cru is a prestigious appellation in the Bordeaux wine region, located on the right bank of the Dordogne River. This designation is distinct from Saint-Émilion AOC, as it adheres to more rigorous production criteria, particularly in terms of yield, winemaking techniques, and aging duration. Wines bearing this label must come from the same delimited areas as those of Saint-Émilion but are subject to a stricter evaluation process to earn the "Grand Cru" title.
