Blue marl - lighter and more aromatic style
Chianti Classico soil types (3)
- Galestro - schistous, crumbly rock - aromatic
- Albarese - calcareous clay - structure and body
- Sand & Sandstone - “smoky”
Montalcino soils
Schistous galestro higher elevation (lighter more aromatic) and clay in lower warmer parts (powerful and riper)
Vino Nobile di Montepulciano DOCG soils
Cooling heavy clay and lighter sandy soil
Aglianico del Vulture DOC soils
Clay, limestone, volcanic (stony, lava, ashy), giving excellent drainage while clay holds water for the drought period in the summer
Dry Creek soils
- Gravel sandy loam on the valley floor
- Gravel red clay loam on the hills
