Which statement about chalk types in Champagne terroir is true?

• A. Belemnite chalk is found at the upper to mid-section; preferred for sun exposure, air circulation and drainage.
• B. Belemnite chalk is never found in Champagne soils.
• C. Micraster chalk is found at the upper slopes.
• D. Chalk types do not affect vine growth in Champagne.

Answer: (A)

In Champagne terroir, where chalk beds shape drainage and heat, the type of chalk in the soil matters for how vines grow. Belemnite chalk, characteristic of the upper to mid portions of the chalk sequence, tends to be more porous and well drained. That porosity supports good air movement around the roots and prevents waterlogging, while the slope position catches sun more effectively. So saying that belemnite chalk is found in the upper to mid-section and is preferred for sun exposure, air circulation, and drainage aligns with how this chalk type influences vine growth. Micraster chalk, by contrast, is associated with different parts of the profile (often lower or deeper layers) and can be less favorable for drainage. The idea that chalk types don’t affect vine growth isn’t correct, since soil drainage, heat, and aeration all influence vine vigor and grape quality. So the statement correctly links belemnite chalk to the upper-to-mid section and to conditions favorable for vine growth.
