Not a borehole: ordered by age, thickness by share of surface.
In the glass. In the Côte de Nuits it is associated with firmly built, structured red wine with ageing potential. That judgement cannot be separated from the steep siting and the colluvial cover that usually lies on top, so read it as a correlation and not as a cause.
Made up almost entirely of the broken stem segments of sea lilies, piled up by currents into shallow banks; the French call it calcaire à entroques. It is a coarse, granular, pale to faintly pinkish rock, hard but well drained, and it was quarried as building stone for centuries. Lower Bajocian, roughly 170.9 to 169.3 million years old.
For the vine. Hard and heavily fractured, so water drains away quickly and the roots can follow the joints deeper into the rock. The topsoil is thin and stony and warms up readily, which can favour early ripening, although aspect and slope weigh more heavily here. In extremely dry years there is a risk of stress, and the active lime content is high.
Lies beneath the lowest bands of part of the grands crus of Gevrey-Chambertin and outcrops in premiers crus such as Les Cazetiers and Les Champeaux.
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: j2a, UIGoζ, l3b-c, t7-l1, j2b.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:53 above the hill and disappears at 17:54 behind the hill: 10.0 hours of direct sun on a clear day. The ridge reaches 18.4° above the horizon to the west. The relief costs 0.9% of the irradiation from April to October, direct and diffuse together.

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), 36% of the far field is forest (BD Forêt), no buildings.
The irradiation loss does include clouds: the average of 2005 to 2023 (PVGIS-SARAH3, EU JRC), not any particular year.

The name
- chaume
- fallow, bare ground, from Latin calmis. Not stubble field as in modern French. Vegetation · 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.

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.
