Champagne AOC

Champagne AOC covers a legally delimited and geographically dispersed vineyard east of Paris. Its main vineyard groupings surround Reims, follow the Marne, cross the chalk slopes south of Épernay, and extend into the Aube, with additional sectors and 319 wine-growing villages. Hundreds of thousands of small plots create an unusually fragmented vineyard landscape.

The climate combines oceanic moderation with continental cold, frost, heat, and storm risks. Hillside exposure helps capture sunlight, while chalk, marl, and limestone provide drainage and water storage. The principal grapes are Chardonnay, Meunier, and Pinot Noir, matched differently to subregional conditions.

The appellation regulates grape origin, yields, pressing, winemaking, secondary fermentation in bottle, maturation, and release. Blending may combine varieties, villages, plots, and years, although vintage, single-village, and single-vineyard wines also exist.

The graph should separate Champagne AOC from its subregions, villages, plots, growers, cooperatives, houses, and individual wines. Unlike Burgundy, most subregional names are not separate appellations, so hierarchy must reflect actual legal status rather than reputation alone. Commercial roles also require precision. A grower may sell grapes, produce wine, work through a cooperative, or do several of these things; a house may source across the appellation while owning vineyards of its own. Modeling producer type and grape origin separately lets users understand a bottle without confusing brand location with vineyard provenance.
