Bedrock

Not a borehole: ordered by age, thickness by share of surface.

In the glass. As a mixture this substrate says little in itself; origin, thickness and slope do the work. The wine can be expected to turn out fuller than on the bare subsoil next to it, but that has not been systematically established. (weak indication)

Not a rock but a collective name for material that slid down the slope through solifluction during the ice ages: a mixture of clay, silt, sand and stone rubble. The composition depends on what lies higher up; above chalk it is rich in lime and light in colour, below Tertiary sands and clays it is acidic and heavy instead. Solifluction itself is an ice-age process and is no longer active; what still moves today is surface wash and tillage erosion.

For the vine. This layer often lies on precisely the right slope positions and is deeper, looser and more fertile than the rock beneath it: more rootable ground, more water reserve, more vigour. The downside is that with a thick layer the root no longer reaches the parent rock, so the character of the subsoil drops out. Drainage is reasonable as long as the slope has enough gradient; on the flat foot of the slope the material stays cold and wet until late in spring.

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: SC, c5b, C.

Grey: sun up, behind the hill or its own slope.

Around harvest the sun rises here at 07:29 above the flat horizon and disappears at 19:28 behind the hill: 12.0 hours of direct sun on a clear day. The ridge reaches 5.7° above the horizon to the northwest.

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), 25% 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.
