Monmousseau is a Loire sparkling wine producer based in Montrichard (Loir-et-Cher), producing traditional-method sparkling wines from Chenin Blanc grown in the Touraine and Vouvray zones of the Loire. Established in 1886, Monmousseau is one of the historic Loire sparkling houses, producing Vouvray Pétillant, Crémant de Loire, and Montlouis sur Loire sparkling all using the traditional method (secondary fermentation in bottle) with Chenin Blanc as the base variety. Loire sparkling wines offer a distinctive alternative to Champagne: higher natural acidity from Chenin Blanc, strong regional character, and a typically demi-sec or brut style.

Loire traditional-method sparkling from Chenin Blanc occupies a specific position in the sparkling wine category: more acidic and food-specific than Champagne (Chenin's natural high acid suits food pairing better than the blended Champagne base), more aromatic than Crémant d'Alsace, and distinctly Loire in character. For programmes needing a quality house sparkling at below-Champagne pricing, or wanting to offer a regional French alternative to Champagne with genuine appellation depth, Monmousseau Crémant de Loire provides the Loire valley reference point.
