Let’s suppose you had friends over for dinner or party, and there was good food, and obviously good drops. Despite having company, you could not finish every bottle of wine that you opened. That is bothering you because, considering the wine fragile nature, you believed that once opened it began to decay almost instantly.
Well, from the moment the bottle is opened, wine comes in contact with air and oxidation process begins. Oxygen and wine have a complex relationship which is not something to be ignored. Oxidation takes place when oxygen meets the wine. It is true that many drops benefit from aeration after opening and simply resting few minutes in the glass; it is after all a matter of a personal taste. However, after a couple of hours, further oxidation will ruin the fun.
The storing solutions depend on what kind of wine you have opened: red or white, aged or ready for drinking, sweet or dry. Well, as far as wine wonders are concern, all wines could live to drink another day with a cork in it and a cool environment.
For instance, a bottle of white wine will resist three or four days if corked and refrigerated while a heavy, red Cabernet might resist a little longer. Most wines will go three to four days, and richer wines a week, so, assuming that you did not throw the cork once you opened the bottle, place the cork back and refrigerate. This is an easy, reliable method when you have no other choices or in a hurry.
Another method you may consider when trying to store the leftover wine will be transferring the remains into a smaller bottle. Doing this, you prevent the oxidation because the fewer wine in the bottle, the longer it will last. Put the cork and refrigerate it, of course. You will probably need a funnel to help complete the task.
In your attempt to preserve you unfinished wine, you may choose to vacuum the air from the bottle with a special device called “wine vacuum.” Anyway, you still have to refrigerate the wine. Keep in mind that there is no such a device able to remove the oxygen completely from the bottle.
If you are a complete believer, you can use a wine preserver spray. This spray contain a harmless blend of gasses which many wine’s wonder assure that it does not react with the wine. It is just protecting it from going bad. However, for those who are not confident with this method, the cork stopper might their next choice. These corks together with metal cones, with or without rubber rings, are cheap and fun.
You might “lose” them in the refrigerator probably in favor of another fresh bottle, but one thing to consider is that wine will not deteriorate in a sense that is unsafe to consume it. It will just taste different, probably dull and sour, but it will not hurt you whatsoever.
Supposedly, you choose another bottle over the refrigerated one. Nothing to worry about. You can use the stored drop in your cooking. Out there are plenty of recipes that require wine. However, do what you think or like with you remaining wine, but do not throw it down the sink.
