The geographical zone occupies part of the interfluve between the Indre and the Cher, two tributaries of the Loire, immediately south of Tours, with vineyards situated on plateau land.
The geographical zone extends across the territory of five communes in the Indre-et-Loire department.
The delimited parcels present essentially brown calcareous soils developed over the upper Turonian or over lacustrine limestone, with some sectors on a residual weathering complex of clays, millstone grits, and coarse sands.
The climate of the geographical zone is a degraded oceanic climate, this sector being among the driest and mildest in the department, with average rainfall of approximately 650 millimetres per year over the Tours conurbation.
The zone benefits from an average of 55 frost days between October and April, a figure lower than that observed in the eastern part of the department, which records 60. (via Wikipedia · CC BY-SA 4.0)
