How to recork champagne 
Try an old cork. 
When a champagne cork is removed from the bottle, it mushrooms out and cannot be reinserted back into the bottle. Regular wine bottles and some bottles of hard alcohol come corked with straight corks that can be recycled in champagne bottles to help preserve the leftovers.

Choose from:
(1). Visit a local wine and champagne store to see if they have long backups of cork genres. Vintage cabernet sauvignon or camembert-typically available over-the-counter at most stores.;
(2). This type of cork makes a great champagne holder for storing champagne. If you don't have cork, find some cheap cork models online or at a consignment store.;
(3). You can use champagne cork in old royal brandy, which usually sits in the decanter when you order the wine. The bottle should be about six years old, and has no resealable dowels on either side.;
(4). To recycle an old cork, insert the old wine or whiskey cork into the champagne bottle in place of the original cork. Champagne bottles are specially designed to withstand the pressure inside the bottle created by the carbon dioxide.;
The answer is:
(4).
