AB The decision-making in the investment of a new line of stoppers based on agglomerated cork requires knowledgeof the composition and its contribution to its performance. For this, it is necessary to observe the leading productson the market and to test a series of prototypes with different formulations. The development of manufacturingproducts made by cork, such as bottle stoppers, benefits strongly from accurate chemical and structural characterizations,correlated to the final material performance. A wise starting point to fulfill such requirementconsist of comparing available products in the market to be compared with different prototypes with varyingcomposition. This work presents a blind characterization of a series of cork samples through a non-supervisedexploratory analysis designed to select agglomerated corks for spirits and still wines in the packaging industry.A total of 18 batches, with 3 of them being high-end commercial products, were used to build 15 differentprototypes. They were subsequently characterized with the exact composition of microgranulated cork as theunknown variable. Statistical results based on 14 parameters related to the physic-thermo-mechanical propertiesindicate that the suitability of selecting the stopper relies on the study of only 4 or 5 of the initial parameters.Hence, it is shown that a reduced number of parameters may be considered to properly describe the mechanicalbehavior of agglomerated cork, allowing the wise choice of the most convenient material for the intendedapplication. The factorial map reveals that the only sample batch manufactured based on the tested prototypescorrelates with the three of the products supplied by the competence.
