Bachet noir (/ˈbæʃeɪ nwɑːr/) is a traditional French variety of red wine grape that is a sibling of Chardonnay.
DNA fingerprinting has shown that it is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot noir, making it a sibling of famous varieties such as Chardonnay and Aligoté.
Gouais blanc was widely grown by the French peasantry in the Medieval ages.
The fact that it is now only found in the Aube, and is descended from grapes that have been grown locally for hundreds of years, suggests that it originated to the north of Burgundy.
Tiny amounts of Bachet noir are grown in the Aube, between Champagne and Chablis.
