Usage Note
Mousseux (as a noun) refers to any sparkling wine that is not Champagne — for example a Crémant or a Cava sold in France. As an adjective it means 'frothy' or 'sparkling': une boisson mousseuse. Champagne is technically a mousseux, but referring to it that way is considered a social blunder in France.
Examples
"Ils ont trinqué avec un mousseux bon marché."
Natural Translation
They toasted with an inexpensive sparkling wine.
