Which region is most associated with limestone-rich marl soil in Champagne?

• A. Montagne de Reims and Côte des Bar
• B. Vallée de la Marne
• C. Côte des Blancs
• D. Champagne city center

Answer: (A)

Limestone-rich marl is a calcareous clay soil texture formed from a mix of lime and clay. In Champagne, this type of soil is most characteristic in the Montagne de Reims and the Côte des Bar, where the bedrock and sediment history give you marl-rich layers that drain well and retain minerals. These soils contribute structure and acidity to the wines, often highlighting Pinot Noir with a crisp, mineral character and good aging potential.

Vallée de la Marne tends to be more alluvial and clay-dominated from river deposits, so it isn’t as closely tied to marl. The Côte des Blancs is renowned for its chalky, pure limestone soils rather than marl, which is why this pairing isn’t the best match for a marl emphasis. Champagne city center isn’t a vineyard terroir, so it doesn’t apply.
