Bedrock
- 100%Rhaetian to earliest Jurassic: sandstone, clay and shelly limestone about 208–200 million years
In the glass. On sandy soils, fragrant wines with fine tannin and less weight are often made, usually via lower vigour and earlier ripening rather than directly from the sand. It is a tendency, not a rule, and a thicker clay layer can overturn the picture completely.
The transition from Triassic to Jurassic, roughly 208 to 200 million years ago, when rivers spread pale quartz sand over clay on a flat coast; the top of the package continues into the lowest Jurassic, the Hettangian. When the sea returned, a shell bank formed on top, the lumachelle with the bivalve Cardinia. In the ground this yields yellow to red-brown sand, tough clay layers and hard sandstone slabs, with little lime.
For the vine. Light, permeable and quick to warm up, so an early soil in which the roots can go deep. The sand retains little water, but the clay layers beneath often form the reserve that carries the vine through the summer. Lime is scarce, so chlorosis is hardly an issue; erosion on the steeper parts, on the other hand, is a point of attention.
Characteristic of the Couchois and of the western edge of the southern Mâconnais, where the Triassic comes to the surface between granite and Jurassic, among other places near Chasselas, Leynes and Saint-Vérand.
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: t7-l1.

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), 31% of the far field is forest (BD Forêt), no buildings.

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.
