Ensured the origin of the cork, begins its maturing and eco-boiling stage which is followed by a rigid selection of the semifinished material. Before proceeding to the production the quality control laboratory sets up a rigorous system which provides multiple tests among which excels the organoleptic check of each incoming batch with a representative sample of at least 400-800 stoppers and/or disks. The gas chromatography makes a verification of the analysis carried out by the panel of expert internal tasters and the material, only after the validation, continues the subsequent processing steps. Washes, IGEA and Te.De.Sys treatments, dedusting, turning, facing, electronic, manual and ponderal selection, ink and fire marking, surface treatment and packaging are the latest stages of our complete and unique quality chain.
