Bedrock
- 100%Limestone of Vermenton, Middle to Upper Oxfordian about 160–157 million years
In the glass. Related to the upper slopes of Saint-Aubin and Santenay: tight, mineral Chardonnay and slender Pinot. Read as a tendency; altitude and aspect do a great deal.
White to beige, partly oolitic and reef limestone from the Middle and Upper Oxfordian (the former Rauracian), deposited on a warm, shallow carbonate platform. On the Côte de Beaune and in the Châtillonnais it forms the hard plateau edge and the upper slope above the Oxfordian marl.
For the vine. Hard, shallow and very free-draining: little water, high lime content, quick to warm. Roots depend on fissures and a thin cover of clay or scree. Usually the highest plots; cool because of the altitude.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:36 above the hill and disappears at 18:05 behind the hill: 10.5 hours of direct sun on a clear day. The ridge reaches 17.5° above the horizon to the south-southwest. The relief costs 1.1% 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), 33% 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.

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.
