The geographical area corresponds to a set of plateaus at moderate elevations of between 210 and 220 metres, interspersed with wide, gently sloping valleys.
The geological substrate consists mainly of Pliocene-age clays and sands, cut through by valleys that have deposited Quaternary-age alluvial clays.
Soils are generally silty-clay, deep, and sometimes hydromorphic, except in a few limited sectors where the materials may be slightly calcareous.
The predominantly cool oceanic climate is modified by continental and southerly influences channelled along the Rhône–Saône corridor, with annual rainfall of around 750 millimetres and a mean temperature of 10.5°C.
The position of the zone to the east of the Morvan massif and the Burgundy plateaus provides a degree of climatic shelter, creating a local thermal advantage and a notable rainfall deficit that is favourable to the vine.
