Grown in the vineyards grow at the top of the large hills on the outlying land of the appellation, and covering an area of around 500 hectares, Petit Chablis is the smallest of the appellations with the Chablis title, being established during January 1944.

The appellation title covers wines not included in the standard Chablis, Premier or Grand Cru titles. The white wines produced here come from exclusively Chardonnay grapes (similar to normal Chablis) and are recommended to be enjoyed when young, providing a slightly-lighter version of Chablis.
