Bedrock

- 55%Bathonian limestone (Comblanchien and Nod) 168–165 million years
Not a borehole: ordered by age, thickness by share of surface.
In the glass. Tends towards taut, firmly built wine that develops slowly. That effect works mainly through soil depth and drought stress and not through a direct transfer from stone to glass.
Shell debris, lime gravel, ooids and oncoids, small knobbly algal balls, cemented into a hard limestone on a warm and shallow platform. This sequence includes the Pierre de Comblanchien from the quarries of the Côte de Nuits and the Pierre de Nod from the Châtillonnais. The Comblanchien recurs under more than one map code, depending on how the map sheet has subdivided the sequence; Bathonian, about 168 to 165 million years old.
For the vine. Hard rock of low porosity that gives a thin, distinctly stony soil with a small water reserve, in which roots follow joints and bedding rather than the stone itself. The stones warm quickly; how much reflected light and heat actually reaches the bunch depends on row orientation and canopy management. The active lime content is high, and on flat ground without a colluvial cover there is simply too little soil.
The quarries of Comblanchien and Corgoloin on the southern edge of the Côte de Nuits; the Pierre de Nod is named after Nod-sur-Seine in the Châtillonnais.

Grey: sun up, behind the hill or its own slope.
Around harvest the sun rises here at 07:26 above the flat horizon and disappears at 18:44 behind the hill: 11.3 hours of direct sun on a clear day. The ridge reaches 10.8° above the horizon to the west-northwest.

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), 32% 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.
