Alluvions indifférenciées, sub-actuelles à actuelles
Not a borehole: ordered by age, thickness by share of surface.
In the glass. Tends towards broader, firmer and somewhat earthier red with more substance in the middle, generally less finely drawn than on limestone. The spread is wide, because plots on the Trias differ greatly in clay content and depth.
Red, green and grey clays with beds of gypsum and beige dolomite, deposited in the Upper Triassic (Keuper). The landscape at the time was a flat coast of lagoons and salt pans that repeatedly dried out, hence the gypsum and the dolomite. In the field it is a thick, soft sequence whose thickness varies greatly from sector to sector and which forms a grassy lower slope beneath the hard limestone edge of the Lias.
For the vine. Heavy, dense clay that holds a lot of water and warms slowly, with late budburst and a cold, wet footing in spring. In a dry summer that very water buffer is the advantage, provided the roots can get through it; compaction and poor aeration are the real problem. Gypsum supplies calcium and sulphur without carbonate, so chlorosis pressure is generally lower than on limestone, although the dolomite beds can raise it locally.
Comes to the surface in the Couchois, among other places around Saint-Maurice-les-Couches, and in the north of the Côte chalonnaise around Aluze, Charrecey and Bouzeron. In Rully the Trias appears at most on the western edge.

Grey: sun up, behind the hill or its own slope.
Around harvest the sun rises here at 08:14 above the hill and disappears at 19:37 behind the hill: 11.4 hours of direct sun on a clear day. The ridge reaches 10.0° above the horizon to the south-southeast.

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), 29% of the far field is forest (BD Forêt), no buildings.

The name
- grand
- large, usually relative to a smaller plot with the same name. Shape and position · Terroirium, Eigen telling over de namen in deze atlas (2026)
- vigne
- vineyard, the ordinary word for planted ground. The most common element in this atlas, usually descriptive rather than distinguishing. Viticulture · Terroirium, Eigen telling over de namen in deze atlas (2026)
This is about the words, not about this plot: the same name can have arisen differently elsewhere.

Share of the delimited hectares. Only legal entities are public in France; everything else stays unnamed. From the public register of legal entities (DGFiP), as of 1 January 2025. The owner is not always the one who works the vineyard: tenancy is common.

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.
