The Clayver 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.
Ceramics certified for food use, controlled porosity, patented hermetic closure, high thermal inertia, easy cleaning.
