The Chablis region of Burgundy is classified according to four tiers of Appellation d'origine contrôlée designation. The top two are the crus of Chablis and include the 7 Grand cru vineyards followed by the lower Premier crus. Wines made entirely from fruit from these vineyards are entitled to list their wines as cru classé Chablis on the wine label. Below these tiers are the lower designations of basic Chablis AOC and Petit Chablis. Soil quality and hill slope play a major role in delineating the differences. Many of the Premier Crus, and all the Grand Crus vineyards, are planted along valley of the Serein river as it flows into the Yonne with the best sites located on a southwest facing slope that receives the maximum amount of sun exposure. All of Chablis' Grand Cru vineyards and many of their better Premier Cru vineyards are planted on primarily Kimmeridgean soil which is believed to impart more finesse and structure to the wines. Other areas, particularly the vast majority of Petit Chablis vineyards, are planted on slightly younger Portlandian soil.
There is one Grand Cru in Chablis with seven officially delineated Grand Cru climats, covering an area of 247 acres, all located on one southwest facing hill overlooking the town of Chablis. There is one vineyard, La Moutonne, located on this hill between the Grand Cru vineyards of Les Preuses and Vaudésir that is considered an "unofficial" Grand Cru and it will appear on wine labels. However, the Institut National des Appellations d'Origine does not recognize La Moutonne as a Grand Cru.

Premier Crus
At the turn of the 21st century, there were 40 Premier cru vineyards in Chablis. The names of many of these vineyards do not appear on wine labels because of an INAO allowance that permits the use of "umbrella names" - where smaller, lesser known vineyards are allowed to use the name of a nearby more famous Premier cru vineyard. Seventeen of the most well known "umbrella" vineyards are bolded below. As of 2009 the official list of the climats accepted for the Chablis Premier Cru includes total of 89 vineyards, names of which could be used on the label. These climats are often inclusive.
