Bedrock
- 100%Aalenian crinoidal limestone and iron oolite 175–169 million years
In the glass. Tends towards taut, tense white wine with plenty of definition and somewhat less flesh. How strongly that comes through depends mainly on the soil depth within the plot, which can vary greatly on this hard limestone.
Hard, crystalline limestone consisting almost entirely of finely broken stem segments of sea lilies, the entroques, piled up by currents on a shallow, agitated seabed. Fresh, the stone is blue-grey and glitters with calcite; at the surface it weathers to beige and rusty brown. It comes with thin layers of iron-bearing oolites and marly, siliceous limestone beds.
For the vine. Hard and compact, so the roots have to follow cracks and fissures; the soil above is usually shallow, stony and quick to dry. The shallow, stony soil warms up quickly, which can bring ripening forward, although aspect and slope weigh more heavily in that than the rock type. The active lime content can be high, and because the iron in the oolites is bound as oxide and barely available to the plant, it does not remove the chlorosis pressure; the choice of rootstock does.
In the Mâconnais the Aalenian usually lies hidden beneath slope scree at the foot of the cliffs; the rocks of Solutré and Vergisson themselves consist mainly of Bajocian Calcaire à entroques and Calcaire à polypiers.
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: j1-2a.

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), 38% 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)
- bussiere
- boxwood, a shrub that grows on limestone. Vegetation · Gérard Taverdet, Noms de lieux de Bourgogne (2007)
This is about the words, not about this plot: the same name can have arisen differently elsewhere.
Who owns land here
No parcel here is registered to a legal entity. In France only those owners are public; parcels of private individuals are not.

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.
