Not a borehole: ordered by age, thickness by share of surface.
In the glass. Because each plot is a different mixture, no reliable flavour rule can be attached to it. Where the layer is deep and fine, in practice rounder, less tense wines go with it than higher up the slope, but that follows from soil depth and position, not from the material. (weak indication)
Not a rock but a collective name for everything that has come down by water and gravity and has come to rest on the valley floor or at the foot of the slope. The composition mirrors what lies above: sandy and lime-free beneath a granite hill, stony and lime-rich beneath a limestone plateau. It is young material, largely from the last ice age and the Holocene, and the layer can be anything from a few decimetres to several metres thick.
For the vine. These positions are generally deeper and more fertile than the slope above, with more fine material and therefore more moisture reserve, which is an advantage in a dry summer. Against that, valley floors collect cold air and water, stay wet and cold in spring and are prone to late frost. Where the subsoil is clayey, periodic waterlogging occurs, and that hampers rooting more than acidity or lime.
Covers a large part of the flatter zones below the crus. Exactly which plots lie on it differs from commune to commune and requires the map itself.
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: FC, j3a.

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), 31% of the far field is forest (BD Forêt), no buildings.

The name
- meix
- an enclosed house plot with garden, from Latin mansus. Typically Burgundian and almost always at the village edge. Ownership and saints · Gérard Taverdet, Noms de lieux de Bourgogne (2007)
- roi
- the king, or the duke who styled himself so. Clos du Roi is seigneurial property. Ownership and saints · Association des Climats du vignoble de Bourgogne, Les noms des Climats (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.
