Located in Polisot in the Côte des Bar, Champagne Marie-Courtin produces Champagne from organically farmed vineyards planted mainly to Pinot Noir. Efflorescence is the estate’s flagship cuvée, sourced from vines grown on Kimmeridgian limestone soils similar to those of Chablis. Fermentation takes place with indigenous yeasts in stainless steel followed by extended ageing on lees in bottle. The balanced 2017 vintage delivered both freshness and depth. Compared with Concordance, Efflorescence is slightly broader and more textured, combining red apple, citrus and subtle toasted notes with fine mousse and pronounced mineral character.
