THE MATURE. Is the new premium version of the CARAT series – developed for wines that are given time to unfold their full potential. Thanks to its precisely balanced microagglomerate structure and a natural cork content of more than 75%, the CARAT X combines the elasticity of a classic natural cork with the advantages of modern microagglomerated corks. The controlled origin of the cork material and the targeted sterilization and deodorization technology ensure high sensory purity.
