From Brut Nature to Doux: how dosage defines every bottle of Champagne

What happened

Every bottle of Champagne carries a dosage designation on its label — a legally defined indicator of residual sugar content that runs from the bone-dry to the generously sweet. The classification spans six recognised categories, each with its own prescribed sugar range, and together they form the framework through which producers communicate style to the consumer before a cork is drawn.

At the driest extreme sits Brut Nature, also known as Zéro Dosage or Non Dosé. It contains fewer than 3 grams of residual sugar per litre and receives no liqueur de dosage whatsoever. One step sweeter is Extra Brut, which may contain between 0 and 6 grams per litre. Brut — by far the most commercially prevalent style — is defined as containing fewer than 12 grams per litre, a threshold broad enough to accommodate a wide range of house interpretations.

Moving along the scale, Extra Sec (sometimes rendered as Extra Dry) falls between 12 and 17 grams per litre, occupying the middle ground between Brut and the sweeter designations. The Sec category, which sits between Extra Sec and Demi-Sec, is not represented in the confirmed data for this article. Demi-Sec, however, is well established: it contains between 32 and 50 grams per litre and is traditionally associated with dessert pairings. At the furthest point on the spectrum, Doux exceeds 50 grams per litre and represents the sweetest category the regulations recognise.

Why it matters

Dosage designations are not merely descriptive — they are statutory. Appearing on every Champagne label, they offer the consumer a reliable guide to the style of wine inside the bottle. Because the categories are legally anchored to specific sugar ranges, they carry a consistency that voluntary tasting descriptors cannot match. A drinker who understands the scale can navigate any producer's range with confidence, knowing that a Brut Nature will always be drier than an Extra Brut, and that a Demi-Sec will always be sweeter than a Brut.

Context

The dosage step occurs after disgorgement, when the temporary cap used during the second fermentation is removed and the wine is topped up. The amount of liqueur de dosage added at this stage determines where a Champagne falls within the classification. The system applies across the appellation, providing a common language for producers and consumers alike.
