DIAM

Brand name (abbreviation for "diamond process"), for a special agglomerated corks for still wines, sparkling wines and spirits (picture). The product was developed by the French company Sabaté, the second largest cork producer worldwide, in seven years of cooperation with the CEA (Commissariat à l'Énergie Atomique). The raw material is high-quality bark cuttings from the cork oak (i.e. no waste products). First, all the wood particles are sieved out of the fine granulate. This is then cleaned with hypercritical carbon dioxide (a state between liquid and gaseous) in a diamond process without chemical substances. The material is thus freed from TCA (trichloroanisole), which is responsible for the dreaded wine defect cork taint, as well as from other numerous molecules responsible for off-flavours. The manufacturer guarantees that no faulty odours or aromas can form later. In this regard, a 100% TCA removal guarantee is given in the form of a multi-year shelf life guarantee.
