The Impact of Bottleneck on the Cork Closures

Study

The Impact of Bottleneck Shape on Functional Parameters of Cork Closures.

This work aims to contribute to a greater understanding of the impact of bottleneck shape and storage temperature on cork stopper performance parameters.

Natural and micro-agglomerated cork closures were seen to have differences in time and temperature, depending on elastic memory, wine absorption, and extraction forces. It was also determined that the extraction force of the micro-agglomerated cork closures is significantly impacted by the shape of the bottleneck, with differences of up to 15 daN.

The ongoing research aims to address the importance of bottleneck shape in the performance metrics of the two types of cork closures, natural and micro-agglomerate.
