T-Cork® Stopper

The T-Cork® stopper is a natural cork stopper with a range of different capsules in plastic, wood and other materials, designed for bottling fortified wines and spirits. Given the alcoholic strength of the drink and the specific nature of the bottle, its function is to prove an efficient seal, easy manual extraction and subsequent re-use.
