Opening a Wine Bottle with a Cork Stopper on Shabbat

Hello,

It is permitted on Shabbat to open a bottle sealed with a cork stopper, even by means of a tool intended for that purpose. If the top of the bottle is coated with wax or the like, with letters or designs impressed in it, the letters should be erased before Shabbat.
