Bedrock
- 6%Massive Bathonian limestone, dolomitic top 166.5–165.3 million years
- 44%Bathonian oolite and fine-grained limestone 168–166 million years
- 50%Bajocian to Bathonian marl 169–166 million years
Not a borehole: ordered by age, thickness by share of surface.
In the glass. Generally yields broader, rounder and earlier-approachable wine than the limestone beds above or below. The marl says little on its own as long as soil depth and slope angle are unknown.
A soft sequence of marl and marly limestone that forms the transition between two hard limestone formations, deposited when the sea became deeper and more turbid at the end of the Bajocian and the start of the Bathonian. It includes the well-known Marnes à Ostrea acuminata, packed with small oysters. In the landscape it is recognisable as a flat, grassy bench between two escarpments, often with springs and wet patches.
For the vine. Marl retains water and nutrients; on this bench the soil is deep and cool and stays wet for a long time in spring. That provides a clear reserve in dry years, but it requires slope and controlled vigour, otherwise the vegetation becomes too lush. Active lime is present, so chlorosis plays a part, and because water sits on the marl the bench is prone to subsidence and slippage.
In the Hautes-Côtes and the Mâconnais it forms the soft intermediate bench between the Bajocian and the Bathonian limestone, usually recognisable by the spring line.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:29 above the hill and disappears at 19:14 behind the hill: 11.8 hours of direct sun on a clear day. The ridge reaches 9.1° above the horizon to the south-southwest.

Computed from the IGN elevation model at 5 m: horizon in 36 directions up to six kilometres, sun position per minute, angle of incidence on the mean slope. Clear sky, with the tree canopy from the IGN forest inventory as a raised horizon (15 m closed forest, 5 m heath, trees within 60 m ignored), 34% of the far field is forest (BD Forêt), no buildings.

Where each figure comes from
- Classification
- The INAO delimitation per denomination, cut against the cadastral parcel. Only the INAO's own plans are legally binding; this map is informational.
- Area
- Computed on the sphere from longitude and latitude (turf.area), not in Lambert-93. For an appellation this is the union of the INAO polygons across commune boundaries, measured on the unclosed geometry; the fifteen metres used to close the outline for the map are not counted. For a climat it is the union of the cadastral lieu-dit polygons with that name.
- Planted
- Parcel area times vineyard cover, where cover comes from the IGN vegetation layer supplemented by the agricultural declaration. Checked against the customs harvest declarations: median deviation 5.1 per cent over a hundred appellations.
- Elevation
- Mean of the elevation-model cells whose centre falls inside the polygon, on a 5 m grid.
- Slope
- Per-cell slope from the elevation model using Horn's method, then averaged over the cells in the polygon.
- Aspect
- Vector mean of the per-cell aspect. A plain average would turn north-east and north-west into south.
- Sun at harvest
- Hours of direct sun on 20 September under a clear sky, with the horizon in 36 directions out to six kilometres and the height of woods and buildings on top of it. Canopy height is measured where LiDAR HD covers the area and estimated from BD Forêt where it does not; the panel states which of the two was used.
- Grape variety by appellation
- Per appellation and colour the permitted varieties from the approved cahier des charges; per appellation and tier the declared hectares of white and red from the customs harvest declaration (product codes). One colour permitted: the main variety of that colour. Two colours: from 85 percent of the hectares that colour applies, in between it is called mixed. Champagne: the dominant variety from the planted hectares per variety per commune from FranceAgriMer. Per polygon the dominant variety of its parts by area. Derived, not measured: the variety per plot exists only in the customs vineyard register, which is not public. In a two-colour appellation a single plot may carry the other variety. Customs withhold small appellations (statistical secrecy), in which case the split is missing.
- Bedrock
- The geological unit covering the largest share of the polygon, from the 1:50,000 geological map. At 1:50,000 the map separates one climat from another, but not what varies inside a climat.
- Organic
- Share of the area certified organic or in conversion, from the CartoBio plot register.
