Terroirs in Burgundy are extremely varied and have a greater influence than anywhere else on the personality of wines and their classification as Grand Cru, Premier Cru, or wine with a Village or regional (Bourgogne) appellation.
A cru (or growth) is a wine of reliably good quality produced from a delimited plot (climat, or lieu-dit) whose qualities reflect the terroir.
The A.O.C. (Appellation d'Origine Contrôlée) classifications take into account:

• The quality of the terroir
• Sun exposure
• Grape variety
• Pruning method
• Yield
• Alcoholic content
• local, praiseworthy, and historically justified viticultural and winemaking practices

In Burgundy the term climat refers to a vineyard plot which usually produces a Premier Cru or Grand Cru, whereas lieux-dits ("named places") produce wines entitled to a village appellation.
Wines produced in these delimited areas reflect this in their name:

• Chassagne-Montrachet Premier Cru "Les Caillerets"
• Chassagne-Montrachet (village appellation) "Les Masures"

However, there is a slight difference for the Grands Crus. Their terroir is deemed to be so great that only the name of the climat appears on the label, with no mention of the village appellation:

• Bâtard-Montrachet

For instance it does not matter if a Montrachet or Bâtard-Montrachet comes from Chassagne-Montrachet or Puligny-Montrachet, the prestige of their "climat" outweighs that of their commune of origin.
