Not a borehole: ordered by age, thickness by share of surface.
In the glass. In so far as there is a tendency, it is towards fresh, linear wines with firm acidity, arising from the coolness and the even water supply. Often the thickness of the clay with flint on top determines more than the chalk itself. (weak indication)
Upper Cretaceous, roughly 90 to 84 million years old. This is true chalk: a white, soft and porous rock consisting almost entirely of the calcareous skeletons of microscopic plankton, settled in a calm, warm sea, with local bands of flint. Under the spade it breaks up into white grit, and on top usually lies a thin cover of clay with flint which in practice forms the topsoil.
For the vine. Chalk retains a great deal of water in very fine pores and releases it slowly, so that drought stress sets in later than the shallow soil depth would suggest, while excess rain still drains away. It is a cool subsoil that warms up late; that delays ripening, which in practice often goes together with higher acidity, and the roots penetrate deep along fissures. The active lime content of the soil is very high, so lime-tolerant rootstocks are no luxury here.
Coniacian and Santonian chalk comes to the surface in Bourgogne only in the far north-west of the Yonne, on the plateaux of the Pays d'Othe, largely outside the planted area.
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: c3, C.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:35 above the hill and disappears at 19:40 behind the hill: 12.1 hours of direct sun on a clear day. The ridge reaches 2.5° above the horizon to the east.

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), 6% of the far field is forest (BD Forêt), no buildings.

The name
- corvee
- land worked under feudal labour duty. A name from feudal law, not a description of the soil. Work and use · Frédéric Godefroy, Dictionnaire de l'ancienne langue française (1881)
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.
