DIAM BOUCHAGE (France) wine corks provide the best quality closure for your wine bottles. DIAM. corks (ref 2) offer consistency between bottles and a guarantee of sensorial neutrality. Diam is an innovative closure that combines the tradition of a cork stopper and the mechanical and organoleptic security of a technological closure: TCA taint-free (below the limit of quantification of 0.3 ng/l) and many other molecules responsible for sensorial deviations. Steady progression on the bottling line and unsurpassed elastic recovery. Prevents leakage, seepage and capillary rise. Cork size: length 44 x width 24.2. these are a larger cork and require a good quality corking tool for insertion. DIAM cork is cleaned via the patented DIAMANT super-critical CO2 process to eradicate 2, 4, 6 – trichloroanisole (TCA) and 150 other compounds. The DIAMANT process guarantees each closure to be free of TCA (below the limit of detection) thereby providing a clean, consistent, sensory-neutral cork.
