Bedrock
- 100%Lithographic limestone, Lower Kimmeridgian 155–152 million years
In the glass. Associated with taut wine with a pronounced line of acidity. Whether that is down to the rock or to the thin, warm, fast-drying soil above has not been settled; harvest timing and yield weigh more heavily. (weak indication)
Extremely fine-grained, dense limestone: lime mud that settled grain by grain in still, shallow and warm water. The term lithographic refers to the fineness of grain, because rock of this type was quarried elsewhere, at Solnhofen, as printing stone. It breaks with a smooth, almost porcelain-like surface and lies in even beds; Lower Kimmeridgian, about 155 to 152 million years old.
For the vine. Dense and barely porous, so water moves almost only through cracks and along the bedding. The soil on top is thin and stony, unless a slope deposit lies over it, and it dries out quickly in July and August. A stony surface layer warms up quickly during the day; how much of that reaches the bunch depends on aspect and row orientation, and the high active lime content remains a point of attention.
Occurs in the Châtillonnais and the Tonnerrois as a hard bed within the Kimmeridgian sequence, rarely planted on its own.
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: j6b.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:39 above the hill and disappears at 18:36 behind the hill: 10.9 hours of direct sun on a clear day. The ridge reaches 11.8° above the horizon to the west-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), 41% 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.
