Which grape is described as very sensitive to the proportion of limestone versus clay in soil?

• A. Chardonnay grapes
• B. Pinot Noir
• C. Sauvignon Blanc
• D. Riesling

Answer: (A)

Soil composition, especially the balance between limestone and clay, has a strong influence on Chardonnay’s character. Limestone-rich sites tend to give higher acidity, a leaner, crisper, and more mineral profile (think chalky, steely notes), while clay-rich soils retain more moisture and nutrients, leading to a fuller, rounder, and more textural wine. Chardonnay is particularly known for showing these contrasts clearly, so it’s described as very sensitive to how much limestone versus clay is in the vineyard soil. For example, wines from limestone-dominant Burgundy sites often come across with bright acidity and mineral notes, whereas clay-dominant sites can yield richer, more opulent wines.
