Not a borehole: ordered by age, thickness by share of surface.
In the glass. Wines from this substrate are often described as finer in structure. In so far as that holds, it is due to the stony, free-draining profile that curbs vigour, not to the rubble itself.
Slope scree that formed in the last ice age when the limestone cliffs above the vineyard broke apart through repeated freezing and thawing, mixed with material washed down from higher up later on. It is not a rock but a blanket of limestone rubble, gravel and sand in a silty, lime-rich matrix, often arranged in distinct layers on the slope. Roughly 115,000 to 12,000 years old, and the composition depends entirely on which rock outcrops higher up the slope.
For the vine. For the vine this is often a favourable profile: deeper than above a hard limestone slab, well drained, stony and poor in clay. Water drains away quickly, which is an advantage in a wet summer and a risk in a dry one, unless the blanket is thick enough. The material is prone to erosion and only works on a slope; at the bottom, where the deposit becomes thick and finer, it soon turns too fertile.
On the Côte de Nuits this scree locally forms the mantle over the Comblanchien, among other places in the scree fans at the mouths of the combes, and around Morey-Saint-Denis and Marsannay. Whether individual climats such as Monts Luisants lie on it must be read from the map layer itself.

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), 44% 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.
