In the glass. There are too few identifiable parcels on this unit to attach a style to it. Where vineyards lie close to the plateau edge, altitude, thin soil and the cooler position explain more than the stone.
The Oolithe blanche is a very pure, pale limestone consisting almost entirely of ooid grains, formed in shallow, moving, warm platform water in the Middle to Upper Bathonian, roughly 167 to 165 million years ago. Its hardness varies from place to place, from fairly soft and granular to compact and hardly porous. In the Yonne, the Châtillonnais and parts of the Mâconnais it forms the plateaux and small cliffs; in the Côte d'Or that role is mostly played by the Comblanchien and the Dalle nacrée.
For the vine. Almost pure lime with little clay, so very permeable and with a small water reserve of its own. Parcels on it usually lie on or just below the plateau edge, where the soil is thin and the vine has to rely on cracks and weathered material brought in from elsewhere. The active lime content is high, and the higher position slows ripening.
Forms the plateau edges and small cliffs in the Yonne, the Châtillonnais and parts of the Mâconnais; rarely planted on its own.

Grey: sun up, behind the hill or its own slope.
Around harvest the sun rises here at 07:38 above the hill and disappears at 17:46 behind the crest of the slope: 10.1 hours of direct sun on a clear day. The ridge reaches 19.4° above the horizon to the west-northwest. The relief costs 0.5% 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), 29% 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.
