Bedrock
- 100%Ypresian sand, sandstone and conglomerate 56–48 million years
In the glass. Tends towards lighter, early-ripening wines with supple tannin and an open, fragrant style. How much of that really comes from the sand cannot be separated from planting density, yield and the age of the vines.
Lower Eocene, roughly 56 to 48 million years old. These are deposits of rivers, alluvial fans and lakes on the southern edge of the Paris Basin: loose quartz sands, locally cemented into hard sandstone beds, with gravel layers and conglomerate full of reworked flint from the older chalk. In the ground it is a granular, rust-brown to ochre-yellow mass without solid rock, with clayey interlayers that can appear and disappear again over short distances.
For the vine. Sand drains quickly and generally warms up promptly in spring, which can get root growth going early; whether ripening really runs ahead also depends on aspect, soil depth and yield. Active lime is virtually absent, so chlorosis is rarely an issue here, but the water supply is small: a dry summer is felt immediately unless the roots reach a clay layer or the limestone beneath. Because the water drains away anyway, a steep slope is not needed for drainage; many of these plots therefore lie flat, and on flat terrain cold air lingers, with a real risk of late spring frost.
In Bourgogne mainly as a Tertiary cover on the plateaux and along the western edge of the Bresse, in the Chalonnais and the Mâconnais.

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), 38% 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.
