Bedrock
- 99%Triassic to Hettangian, undifferentiated about 235–199 million years
In the glass. Tends towards fuller, somewhat firmer wines with more body than tension, provided the drainage is right. Because it is a mixture of three formations, this code says little about style in itself. (weak indication)
A catch-all on the map: clayey Triassic, Rhaetian and Hettangian have not been separated here. It comprises variegated clay and marl from a dry coastal plain, above that Rhaetian sandstone from when the sea returned, and finally thin limestone and marl from the first Jurassic sea. In the ground you see mainly clay with sandy layers and a few thin hard beds, roughly 235 to 199 million years old.
For the vine. Clay dominates, so the water buffer is in principle large, although heavy clay can crack in persistent drought and hold water so tightly that the vine can no longer get at it. The downside is a cold, wet start in spring and slow drainage on flat terrain, so that slope and drainage decide everything here. The lime content varies widely within the same unit, from virtually lime-free clay to marl with active lime, so the chlorosis risk differs from plot to plot.
Among other places at the foot of the slope in the Côte Chalonnaise around Buxy and Montagny, and in the valleys of the Mâconnais where the Jurassic limestone ends against the old massif.
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: tA-l1.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:37 above the hill and disappears at 17:32 behind the hill: 9.9 hours of direct sun on a clear day. The ridge reaches 22.1° above the horizon to the west. 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.
