How to Read a Champagne Label: Everything That Matters

A Champagne label hides more useful information than almost any other wine label in the world. Two letters and a number tell you who actually made the wine.

Pick up any bottle of Champagne and turn it around. Near the bottom, in tiny print, you’ll find two letters followed by a registration number. That’s where the story starts. Anyone who can read a Champagne label knows who made the wine, how sweet it is, what grapes are in it, and often which village they came from. The rest of the label is marketing. This piece decodes the code.

The producer code

The single most important thing on a Champagne label is the one most people walk straight past. A tiny code at the bottom: two letters and a registration number. Those letters tell you who made the wine.

NM, Négociant-Manipulant. A house that buys grapes, and sometimes base wines, from growers and produces Champagne under its own name. The major houses, Moët & Chandon, Veuve Clicquot, Bollinger, Pol Roger, are all NM. They usually own some vineyards but buy in most of their fruit.

RM, Récoltant-Manipulant. A grower who farms their own grapes and makes their own Champagne. This is grower Champagne. Often smaller production, terroir-focused, increasingly visible on serious wine lists. Egly-Ouriet, Selosse, Dhondt-Grellet are reference points.

CM, Coopérative de Manipulation. A cooperative that pools members’ grapes and produces Champagne collectively. Nicolas Feuillatte, France’s largest-selling Champagne brand, is a CM.

RC, Récoltant-Coopérateur. A grower who sends grapes to a cooperative but sells the finished wine under their own label.

MA, Marque d’Acheteur. A buyer’s own brand. A supermarket or restaurant label where someone else makes the wine. Common in the UK supermarket sector.

Why does this matter? NM and RM stand for two philosophies. NM prioritises consistency and house style across millions of bottles. RM expresses a specific place, often a single village or even a single vineyard.

My take: at the same price point, an RM almost always gives you more wine for the money than an NM. With the big houses you pay for marketing, glass and distribution. With a grower that budget goes into the vineyard.

Dosage: The Sweetness Level

Every Champagne label carries a dosage designation, indicating residual sugar:

Brut Nature / Zero Dosage / Non-Dosé. 0 to 3 g/L. No added sugar, or the legal minimum. Bone dry, austere, unforgiving. Works best with high-quality, ripe fruit.

Extra Brut. 0 to 6 g/L. Very dry. Lean, mineral, food-friendly.

Brut. Under 12 g/L. The standard. Dry on the palate despite the residual sugar. By far the most common style.

Extra Sec / Extra Dry. 12 to 17 g/L. Slightly sweet, more than Brut despite the “dry” name. Common in Prosecco, less so in Champagne.

Sec. 17 to 32 g/L. Noticeably sweet. Rarely seen in quality Champagne.

Demi-Sec. 32 to 50 g/L. Medium sweet. Traditional pairing with desserts.

Doux. Over 50 g/L. Sweet. Rare today, historically popular in nineteenth-century Russia.

Blanc de Blancs / Blanc de Noirs

If either of these appears on the label:

Blanc de Blancs. White grapes only. In Champagne that almost always means 100% Chardonnay. Lighter, citrus and chalk, higher acidity, generally better for long ageing.

Blanc de Noirs. White Champagne from red-skinned grapes, Pinot Noir, Meunier, or both. Fuller-bodied, fruitier, often a richer texture despite being a white wine.

If neither appears, the Champagne is a blend of white and red grapes. The most common style.

Vintage or non-vintage

A year on the label means a vintage Champagne, made from a single exceptional harvest. No year means non-vintage, a blend across multiple years. For the full breakdown, see our piece on non-vintage vs vintage Champagne.

Village and Cru Classifications

If the label mentions a village name, Grand Cru or Premier Cru, that refers to Champagne’s classification system.

Grand Cru. 17 villages rated at 100% on the Échelle des Crus, the historic grading system. Aÿ, Cramant, Avize, Le Mesnil-sur-Oger, Verzenay and Bouzy are among them.

Premier Cru. 44 villages rated 90 to 99%. Quality vineyards, but below Grand Cru.

In grower Champagnes this information matters most. It tells you the village the grapes came from, and gives you a sense of the style. Côte des Blancs Grand Crus are typically Chardonnay, mineral and precise. Montagne de Reims Grand Crus are often Pinot Noir-dominant and fuller.

Other terms you’ll see

Récemment dégorgé (RD). Recently disgorged. The wine spent extended time on the lees and was disgorged close to release. More autolytic complexity, exceptional freshness. Bollinger RD is the most famous example.

Réserve. No legal definition in Champagne. A marketing term suggesting older reserve wines in the blend.

Organic / Biodynamic. Increasingly common. Look for Demeter or Ecocert certification logos.

Net content. Standard 75 cl. Also common: 37.5 cl (half bottle) and 150 cl (magnum, ages better than standard bottles).
