The soil in Chablis is known as Kimmeridgean. Located in a sedimentary basin, this low-lying zone was gradually covered by the material that today make up the soil and subsoil of this wine region. One finds subsoils of gray marl which alternate with bands of limestone, sometimes very rich in fossils of Exogyra virgula, a small oyster that is characteristic of the marl from the Middle and Upper Kimmeridgean.

Domaine Christophe & Fils is a small estate and venture started in 1999. Sébastien Christophe took over the family operation - a small half hectare in Petit Chablis. Slowly he has acquired pieces plots as well as renting vineyards that he farms entirely. Today, Sebastien produces three 1er Cru. The Domaine is located on the Fyé plateau, across the river from the town of Chablis. The hills are steep here and overlook Les Clos, Blanchots and Montee de Tonnerre. Here vinification takes place in stainless steel tanks with a use of older barrels for the 1ers Crus.
