1. The closure keeps smoothly on all standard champagne and champagne bottles (eimal had a narrower Prosecco bottle to which he was not tight) 2. It keeps the carbon dioxide back safely, but 3. Of course, pressure builds up in the partially emptied bottle - that is something everybody loses tingling champagne, the mixture is allowed to stand 4. The closing date keeps safe even at high pressures zielmlich 5. he sees wirlich very good and 6. has (in my opinion) an extremely good price-performance ratio
