Brut Nature / Zero Dosage

What It Means

In traditional champagne production, after disgorgement (removing the spent yeast lees), a small amount of sugar solution called the liqueur d'expédition or dosage is added. This balances acidity and shapes the final style. Brut Nature (also called zero dosage, non-dosé, or pas dosé) means no sugar is added at this stage — the residual sugar must be below 3 g/L.

The Dosage Scale

• Brut Nature / Zero Dosage: 0–3 g/L residual sugar
• Extra Brut: 0–6 g/L
• Brut: 0–12 g/L
• Extra Dry: 12–17 g/L
• Sec/Dry: 17–32 g/L
• Demi-Sec: 32–50 g/L
• Doux: 50+ g/L

Why It Matters

Zero dosage strips away the final layer of winemaker manipulation. What remains is the pure expression of the grape, the terroir, and the vintage. For natural champagne producers like Romain Henin and Legrand-Latour, brut nature is not a stylistic choice but a philosophical commitment — if the wine is healthy and balanced from healthy vines, it needs neither added sugar nor added sulfur.

Climate Change Connection

Rising temperatures in Champagne mean grapes now reach higher sugar levels (and therefore higher alcohol after fermentation) than they did a generation ago. Where grapes once produced base wines at 9% ABV with searing acidity, they now routinely reach 11–13%. This shift has made zero-dosage champagne more viable: the wines have enough natural ripeness and lower acidity to stand on their own without corrective sugar.
