Clayver: innotion, technology and tradition.

Precision and scientific verification of materials.

Clayver is a ceramic container designed specifically for winemaking, including in this definition fermentation, preservation and refinement of the product. It is the result of a long work of research and experimentation.

All containers are produced by us, under our direct supervision, from raw materials that we carefully select from the best suppliers, to ensure uniformity and consistency in the final product.

Why stoneware?

The ceramic stoneware is a homogeneous material, together with the considerable resistance to compression, there is a good resistance to flex-traction, considering the stone nature, and a high hardness.

We are champions
of traceability

  • Ceramics certified for food use
  • Controlled porosity
  • Patented hermetic closure
  • High thermal inertia
  • Easy cleaning

Clayver stoneware material

Thanks to traceability and certifications, Clayver stoneware is a guaranteed material.

Clayver ceramic wine barrels are made of a particular homogeneous and compact natural ceramic stoneware. This material is similar in many aspects to a natural granite: it is impermeable to liquids and therefore it does not need any precaution in order to avoid evaporation.

The intrinsic microporous structure of the ceramic material can allow a gaseous exchange with the outside of the container but only in limited quantities and on very long time scales. The container is therefore also suitable for long aging.

Clayver is a clever choice. It is distinguished by the use of excellent materials and a production system that guarantees the repetitive quality of moulding.

Clayver’s added values

  • The use of an excellent material
