CHANDON Argentina produces sparkling wines in Mendoza, where cool-climate conditions favor the precision and acidity essential to méthode champenoise. The winery's portfolio centers on Chardonnay and Pinot Noir—grapes that define elegant, structured bubbles. The Brut Extra Cuvée Spéciale Baron B, a blend of both varieties, stands as the flagship, while the Cuvée Réserve Blanc de Blancs showcases pure Chardonnay character. The Brut Fresco offers a lighter expression of the same core grapes. Decanter, Wine Enthusiast, and Wine Spectator have assessed the range, with the Baron B and Blanc de Blancs receiving particular recognition. These are wines built on the classical sparkling-wine template: dry, mineral-driven, with the textural complexity that comes from traditional production methods applied to Argentine fruit.
