Limestone, clay and more: different soil types

Soil type can vary from limestone to clay to sandy and gravelly, each of which affects the wine in a unique way.

Ideal for Chardonnay and Pinot Noir. Calcareous soils promote the acid structure and minerality of the wine.

Wines grown in clayey soils, such as many Bordeaux varieties, tend to be fuller and more structured.

Minerality: An expression of the soil

Some wines, especially white wines like Riesling, can have a distinct mineral character. This is often a direct result of the soil composition, which can be rich in minerals such as slate or granite.

Water retention capacity: finding the balance

Soils with good water retention capacity can be crucial in dry climates. They allow the vines to obtain sufficient moisture even during stressful periods, which increases fruit quality.

Microorganisms: The invisible helpers

In addition to mineral components, organic materials and microorganisms also play a role. They support the absorption of nutrients and can even contribute to the complexity of the taste.
