Wine grapes grow best in well drained sandy soils, rich in minerals
• Clay: Rich, structured wines - Muscular wines with high extract and color
• Sand: Aromatic / Light colored wines - Elegant wines with high aromatics, pale color and low tannin
• Silt: In the middle - Smooth and round wines with slightly less acidity
• Loam: Too fertile unless blended results in thinner wines
• Rocky: Retains heat and creates sweet wines
• Gravel: Located in shallow soil that is prone to heat . Leads to earlier ripening of grapes, which is advantageous in cool climate. Gravel also drains well, absorbing and radiating heat from the wines.
• Calcaire: retains moisture (in dry vintages), adds minerals to the soil, Good drainage. Allows vines to develop deep roots (with heat, clay drys and forms cracks).
Favorable soils:
• Alluvial soil; combination of clay, sand, gravel and silt
• Calcareous soil; composed of calcium carbonate, chalk or limestone
• Loam soil; mixture of clay, silt and sand
