Bedrock
- 14%Colluvium, mixed slope deposit about 0.1–0 million years
- 18%Campanian chalk of Reims 83.6–79 million years
- 69%Santonian chalk of Châlons 86–84 million years
Not a borehole: ordered by age, thickness by share of surface.
In the glass. The distinction from the Campanian chalk cannot be firmly made in practice; slope, soil depth and vine age weigh more heavily. (weak indication)
White chalk with the sea urchin Micraster coranguinum, deposited on an open, fairly deep shelf between roughly 86 and 84 million years ago, with flint bands at several levels, unlike the flint-poor Campanian chalk above it. It is the same soft, porous lime mud as the younger chalk, locally with harder, cemented beds. The name Craie de Châlons refers to Châlons-en-Champagne, not to the Châlons-sur-Vesle of unit e3cC.
For the vine. The physics of chalk is that of all chalk: a large store of water in fine pores, slowly available, and rooting that follows cracks to several metres deep. The soils generally have a high active lime content, with the associated risk of chlorosis and the choice of lime-tolerant rootstocks. Where this chalk lies flat and the soil above it is thin, it quickly becomes meagre and cold in spring.
BRGM geological map at 1:50,000. It tells vineyards apart, not plots within a vineyard. The link between rock and taste is indirect: soil depth, water and warmth do the work, and slope, vine age and the cellar do the rest. Units on that map: c4, c5a, C.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:52 above the hill and disappears at 19:22 behind the hill: 11.5 hours of direct sun on a clear day. The ridge reaches 5.9° above the horizon to the 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), 22% of the far field is forest (BD Forêt), no buildings.

The name
- est
- east, usually a split of a named plot. Shape and position · Terroirium, Eigen telling over de namen in deze atlas (2026)
- cote
- slope, the flank of a ridge. The word that gave the whole region its name. Relief · Association des Climats du vignoble de Bourgogne, Les noms des Climats (2026)
This is about the words, not about this plot: the same name can have arisen differently elsewhere.
Who owns land here
No parcel here is registered to a legal entity. In France only those owners are public; parcels of private individuals are not.

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.
