As is always the case: the most important aspect is the quality of the material – for natural corks above all. To protect the valuable contents, it has to be break-proof, pressure-tight and extremely dense. Today, sparkling wine corks are usually manufactured and pressed using machines. Sometimes, the pressing also takes place using a hand-operated machine. Afterwards, the cork is pressed into the bottle using a tappet. And only we can take it out again. An exhilarating feeling. Isn't it?
