The three official tiers of French wine quality classification:

AOC (Appellation d'Origine Contrôlée) indicates the geographical origin, quality and (generally) the style of a wine. For example, Burgundy's regional AOC Bourgogne Blanc covers more than 300 parishes, and denotes dry white wines made from Chardonnay, Pinot Blanc or Pinot Gris. By contrast, AOC Romanee-Conti Grand Cru covers just four acres of top-quality vineyard and denotes dry red wines made exclusively from Pinot Noir. The Europe-wide equivalent of AOC is AOP (Appellation d'Origine Protégée). All Grand Cru and Premier Cru wines fall into the AOC category.

• Grand Cru is the very highest classification of French wine. The term can refer to a wine in one of two ways, either a) the plot of land where the grapes are grown or b) the chateau at which the wine is made. The former applies most famously in Burgundy, Alsace and Champagne (but is also used in Languedoc and the Loire Valley). The latter is exclusive to Bordeaux.
• Premier Cru denotes either 1) a vineyard plot (most often in Burgundy) of superior quality, or 2) the very highest tier within a Grand Cru classification (such as the 'Premier Grand Cru Classé' chateaux of Bordeaux).

Vin de Pays means 'wine of the land', although it is often translated as 'country wine'. Its Europe-wide equivalent is IGP (Indication Géographique Protégée). This category focuses on geographical origin rather than style and tradition, and gives winemakers greater stylistic freedom than AOC. Vin de Pays was introduced in the 1970s, and by the year 2000 there were more than 150 individual VDP titles, covering about a quarter of French wine production. For comprehensive information about these, see Vin de Pays - IGP.

Vin de France replaced the outdated Vin de Table category in 2010, but remains the most basic quality tier for French wine. This is the least regulated (and least used) of the three categories; Vin de France wines can be made from grapes grown anywhere in France, but their labels do not mention a specific region of origin. Vintage and grape variety statements are optional. See Vin de France.
