Why do not we have nature corks? There are 2 types of champagne corks, once as cylindrical or mushroom shaped.
The cylinder shape could still be pressed in, but how to fix? we are talking about 6 bar pressure
For the mushroom-shaped (with wire hanger fixable) we have until today found no suitable device for pressing in, small professional gadgets start at approx., 8.000.- Euro to us are thus outside the budget for the hobby of wine making
