Champagne Knowledge

Assemblage
The blending of base wines — from different villages, grape varieties, and sometimes different vintages — into the cuvée that will undergo second fermentation.
Autolysis
The slow breakdown of spent yeast cells during extended lees ageing, releasing compounds that build bread, brioche and savoury notes in champagne.
Blanc de Blancs
A champagne made exclusively from white grapes — in practice, 100% Chardonnay. Known for precision, linearity and long ageing potential.
Blanc de Noirs
A white champagne made entirely from black grapes — Pinot Noir, Meunier, or a blend of the two — pressed carefully to avoid colour extraction.
Brut Nature
A champagne category containing 0 to 3 g/L of residual sugar with no added dosage. Also labelled 'Zéro Dosage', 'Dosage Zéro' or 'Pas Dosé'.
Cuvée
Two meanings in champagne: (1) the first and finest 2,050 litres pressed from 4,000 kg of grapes; (2) a specific wine released by a house — e.g. Krug Grande Cuvée.
Dégorgement
The removal of the yeast sediment collected in the bottle neck after remuage, done by freezing the neck and expelling the frozen plug.
Dosage
A small addition of liqueur d'expédition — typically a mixture of reserve wine and cane sugar — added after disgorgement to adjust the final sweetness of a champagne.
Grand Cru
In Champagne, one of 17 villages whose vineyards are rated at 100% on the old échelle des crus. Wines sourced entirely from these villages may bear the Grand Cru mention.
Méthode Traditionnelle
The sparkling winemaking process involving a second fermentation in the same bottle the wine is sold in. Formerly called méthode champenoise, a term now reserved for Champagne AOC.
Millésimé
A champagne produced exclusively from grapes harvested in a single declared year. Typically released only in years considered exceptional by the producer.
Non-Vintage (NV)
A champagne blended from wines of multiple years, designed to express a consistent house style rather than a single harvest. Typically 80%+ of a house's production.
Premier Cru
In Champagne, one of 42 villages one tier below Grand Cru on the old échelle des crus (rated 90–99%). Source of many respected single-village bottlings.
Prise de mousse
The second fermentation that takes place in the bottle — the step that turns a still base wine into sparkling champagne.
Récoltant-Manipulant (RM)
A grower-producer who makes and sells champagne exclusively from grapes they have grown themselves. Identifiable by the 'RM' code on the label.
Remuage
The gradual rotation and tilting of bottles that gathers the yeast lees into the neck before dégorgement. Invented by Madame Clicquot in 1816.
Saignée
A rosé production method where colour is drawn from black grape skins by a short maceration before pressing. Less common in champagne than the blended rosé method.
Terroir
The combination of soil, climate, aspect, and human practice that gives wines from a specific place their distinctive character.
