Doux is a classification for sparkling wine to indicate that the amount of residual sugar is 50 g/L or more. The total scale used contains the classifications – from very dry to very sweet – Brut Nature, Extra Brut, Brut, Extra-Sec (or Extra-Dry), Sec (or Dry), Demi-Sec and Doux. ‘Doux’ therefore indicates that the sparkling wine is very sweet. See also ‘dosage’.
