Bedrock
- 99%Upper Kimmeridgian limestone and marl about 152–149 million years (approximation, regional division)
In the glass. Tends towards somewhat straighter, less broad wine than the marl-rich lower part of the slope. The difference is subtle and in practice is overshadowed by position and soil depth.
The upper part of the same Kimmeridgian package, roughly 152 to 149 million years old. Here too limestone beds and marls alternate, but higher in the sequence the limestone beds gain in weight and hardness, towards the much harder Portlandian limestones that cap the plateaux. The French map term Kimmeridgien is a regional division and does not coincide exactly with the international stage (154.8 to 149.2 million years), so the age given is an approximation.
For the vine. Slightly less water-retentive and slightly stonier than the marl-rich base below, often with a thinner soil and more loose limestone grit at the surface. That gives fast drainage and a soil that warms up readily, but the reserve for a dry August is smaller. A high active lime content remains a point of attention.
Found at the upper edge of the Chablis slopes, where the package passes into the hard Portlandian limestones of the plateaux.

Grey: sun up, but behind the hill or the vineyard's own slope.
Around harvest the sun rises here at 09:06 over the crest of the slope and disappears at 19:50 behind the hill: 10.7 hours of direct sun on a clear day. The ridge reaches 24.6° above the horizon to the northeast.

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), 23% of the far field is forest (BD Forêt), no buildings.

The name
- perriere
- quarry or stony ground, from pierre. In Burgundy usually a former quarry; at Dijon Roserot simply notes the town's old quarries. Soil and stone · Alphonse Roserot, Dictionnaire topographique du département de la Côte-d'Or (1924)
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.
