About the data
This directory is assembled from public sources, deduplicated and normalised. Nothing here is a scraped copy of a single site — the value is in the merge. Here is exactly how it is built, and where it is imperfect.
Sources
| Source | What it contributes |
|---|---|
| Champagne.fr producer directory | Geocoded producer records: address, village, region, contact details, visiting activities, languages, environmental certifications, editorial description. |
| Maisons de Champagne | House dossiers for the major maisons: foundation date, company profile, vineyard estate, staff, cuvée lists. |
| Producers' own websites | Cuvée-level detail: product names, styles, dosage, ageing and descriptions, discovered from each producer's own range pages. |
How records are merged
Each source is normalised to a common schema, then producers are matched on a normalised name key (accents stripped, “Champagne / Maison / Domaine” prefixes removed, punctuation ignored). Where a producer appears in more than one source, its record is enriched rather than duplicated, and the producer page shows a “verified across N sources” badge. Coordinates come from the geocoded directory records.
Current build: 882 producers, 2,103 cuvées, 808 with coordinates. 59 producers appear only in the cuvée dataset and therefore have no map pin.
Normalisation applied for display
- Names — source records arrive in mixed case (“CHAMPAGNE A LETE”, “champagne alain bedel”). Names that are entirely upper- or lower-case are re-cased for display; the original is retained in the data.
- Dosage — free text is mapped to the standard scale: Brut Nature, Extra Brut, Brut, Extra Dry, Sec, Demi-Sec, Doux. Values that cannot be classified are left blank rather than guessed.
- Style — mapped to Blanc de Blancs, Blanc de Noirs, Rosé, Vintage, Classic blend, or other Champagne wines.
- Price — the directory records price bands, not live prices. Bands are shown as ranges (“€20–30”); no price here is a live retail price.
- Provenance vocabulary — internal pipeline values are translated for readers (for example, directory_seed_only becomes “from the official growers' directory”).
Known limitations
- Coverage is uneven: producers with their own websites have far richer cuvée data than those listed only in the directory.
- Some descriptions are in French, as supplied by the producer. They are shown as written rather than machine-translated.
- Price bands and cuvée ranges reflect the data vintage below, not today's market.
- Images are not republished. Where no image can be used safely, a gold monogram is generated instead.
- Name-key matching is conservative: a small number of producers may appear twice under materially different trading names.
