These sub-soils were formed in deep sea areas over millions of years, as the result of tiny, calcareous particles settling down to the sea bed.
​
Approximately 2 million years ago, the sea receded from the land mass that is now Tuscany, exposing these deep, fine-grained layers of clay. Blue Clays retain moisture, releasing it slowly to vine roots even after weeks or months after the last rains, so that grapes growing on this type of terrain tend to ripen slowly and evenly and reach maturation late, which fosters aromatic complexity.
​
The presence of limestone in the sedimentary clay adds complexity to the wine’s flavor. The best wines made from grapes grown on these soils boast a soft, even texture.
