What is the main soil type in Champagne and what does it do?

• A. Chalky soil—high water retention
• B. Limestone—chalky soil with heat reflection
• C. Kimmeridgian soil—chalky, higher water and heat retention
• D. Gravel—improves drainage

Answer: (C)

Champagne is dominated by a chalky calcareous soil, specifically Kimmeridgian soil, which is a chalky marl rich in clay and fossils. This combination creates great drainage, while the clay and calcareous material retain some water and trap heat so the soil warms during the day and releases heat more slowly. In the cool Champagne climate, that heat retention helps grapes ripen more evenly and maintain acidity, which is essential for making sparkling wine with the structure and precision Champagne is known for. So, the chalky, higher water and heat retention characteristics of Kimmeridgian soil explain why this soil type is so influential for the region’s wines.
