Although many wines are packaged with reusable screw caps, several others are sealed primarily with corks. Because these corks lose their shape once they are removed from the bottle's neck, it is vital to employ a secondary sealing mechanism if you do not wish to drink or cook with an entire bottle in one setting. Doing so will preserve both the quality and taste of the wine for subsequent pours. Here you will find how to seal wine bottles with minimal cost and effort.
How to Seal Wine Bottles
Purchase a wine sealer. These sealers work by creating a tight vacuum seal over the top of the opened bottle. Wine sealers come in a variety of price points and with varying sealing mechanisms, although all of them can be utilized many times over with proper handling and usage. See the resources section for more information on where to buy wine sealers.
Place the bottom of the wine sealer over the top of the unscrewed and/or uncorked bottle. The mouth of the wine bottle should be fully encapsulated by the wine sealer with its vacuum latch in an upward position. If there is no latch, be sure that the bottom of the wine sealer is properly aligned with the mouth of the bottle so it may be screwed in place.
Seal the wine bottle by lowering the vacuum latch until it completely rests in a downward position. The wine sealer itself should not be tipped to one side or other after the latch has been lowered; this may compromise the strength of the seal. Screw-top wine sealers should simply be turned clockwise until securely in place.
Reopen sealed wine bottles by reversing the actions taken in Steps 1-3.
Many wine sealers employ a screw cap as opposed to a vacuum latch. These screw-cap sealers should be turned only until expanded within the neck of the bottle; screwing too tightly may cause the break.
Champagne stoppers also can be used to seal both sparkling and non-sparkling wines, although the speed with which you are able to seal sparkling beverages will determine the level of preservation of the bubbly carbonation.
Prevent damage to your wine sealer by slowly lowering and raising the latch every time you seal a bottle. Doing this too quickly may crack the plastic coating of the sealer or even permanently damage the sealing mechanism.
