Not a borehole: ordered by age, thickness by share of surface.
In the glass. The light, quickly warming soil gives earlier ripening, which usually produces suppler wine. Aspect, soil depth and the high share of Meunier weigh more heavily here than the type of stone itself.
An alternation of loose sand and soft, sandy shelly limestone from the Middle Eocene, roughly 48 to 41 million years ago. The Tuffeau de Damery is a light, porous stone full of shells from a warm sea, deposited in a high-energy environment at some distance from the coast; it is known from Fleury-la-Rivière. In the ground this yields a light, granular mixture of sand and crumbly limestone.
For the vine. Light, warm soils that warm up quickly in spring and drain well, with a moderate water store that can become tight in a dry summer. The stone is soft enough to let roots through, so the vine gets deeper than the soil thickness would suggest. The soils are rich enough in lime for some risk of chlorosis, and on steep sections erosion is a point of attention.
Characteristic of the Vallée de la Marne around Damery, Cumières and Fleury-la-Rivière.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 07:38 above the hill and disappears at 19:12 behind the hill: 11.6 hours of direct sun on a clear day. The ridge reaches 10.9° above the horizon to the north.

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), 27% of the far field is forest (BD Forêt), no buildings.

The name
- fontaine
- spring or well. A name saying that water came to the surface here. Water · Gérard Taverdet, Noms de lieux de Bourgogne (2007)
- 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.

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.
