Cru is a wine term used to indicate a high-quality vineyard or group of vineyards. It is a French word which was originally used to refer to both a region and anything grown in it, but is now mostly used to refer to both a vineyard and its wines. The term is often used within classifications of French wine. By implication, a wine that displays the name of its cru on its wine label is supposed to exhibit the typical characteristics of this vineyard or group of vineyards. The terms premier cru and grand cru designate levels of presumed quality that are variously defined in different wine regions.

Wine labels are important sources of information for consumers since they tell the type and origin of the wine. The label is often the only resource a buyer has for evaluating the wine before purchasing it. Certain information is ordinarily included in the wine label, such as the country of origin, quality, type of wine, alcoholic degree, producer, bottler, or importer. In addition to these national labeling requirements producers may include their web site address and a QR Code with vintage specific information.
