Bedrock
- 14%Old river terraces, gravel and sand Midden- tot Laat-Pleistoceen, niet gedateerd
- 29%Marl and marly limestone, upper Bathonian to Oxfordian (undifferentiated) 166–155 million years
- 33%Massive Bathonian limestone, dolomitic top 166.5–165.3 million years
- 22%Bathonian oolite and fine-grained limestone 168–166 million years
Not a borehole: ordered by age, thickness by share of surface.
In the glass. Where the soil stays thin, this tends towards compact, firm wine that opens slowly and shows little volume. In a hot, dry year the main effect is above all water stress, not a flavour that comes from the stone itself.
Thick, hard, virtually unbedded limestone, formed on a warm shallow platform where fine lime mud was bound by algae and burrowing animals. The well-known Comblanchien belongs to this level and is quarried as building stone; it recurs under more than one map code, depending on how the map sheet has subdivided the sequence. At the top the rock is dolomitised, so that on weathering it breaks up into a more crumbly, sandier material; Upper Bathonian, 166.5 to 165.3 million years old.
For the vine. This is one of the hardest and most erosion-resistant rocks of the Côte and it forms the rocky upper edge of the slope, with very thin, extremely stony soils and almost no water reserve. Roots have to rely on joints and fissures, the soil warms quickly, drains completely and is strongly calcareous, so that without a colluvial cover or a marl band beneath the vine suffers in a dry year. The dolomitised top weathers to a sandier, looser soil with less active lime, although the total carbonate content remains high.
Forms the hard upper edge of the Côte de Nuits, with the well-known quarries at Comblanchien and Corgoloin.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:46 above the hill and disappears at 18:51 behind the hill: 11.1 hours of direct sun on a clear day. The ridge reaches 9.3° above the horizon to the west.

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), 33% of the far field is forest (BD Forêt), no buildings.

The name
- clos
- an enclosed plot, walled or hedged. In Burgundy the wall often carries a monastic or seigneurial past; clou and cloux are the same root in diminutive form. Ownership and saints · 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.
