Oxygen in the air is the ultimate killer of wine. Under the action of acetic acid bacteria, rich wine can be turned into uncharacteristic vinegar. Therefore, when storing open bottles of wine, it is necessary to minimize its contact area or opportunity with oxygen. Common methods include: cold storage, bottle changing, vacuum isolation or inert gas isolation.

1, refrigeration method

Refrigerator is an ideal place for daily cold storage. The low temperature in the refrigerator can effectively slow down the chemical reaction and slow down the oxidation rate of wine after opening. In addition, cooling can inhibit the activity of acetic acid bacteria and slow down its influence on wine.

2. Bottle changing method

Changing bottles means changing a large bottle into a small one. First, divide the whole bottle into smaller bottles by changing bottles, then add a wine stopper and put it in the refrigerator. However, some people think that the process of changing bottles exposes the wine to the air and affects the flavor of the wine.

3. Vacuum isolation method

Vacuum isolation method is to use a vacuum pump (such as a wine saver) to extract the air from the wine bottle and isolate the wine from oxygen. This method seems to be effective, but some people think that the vacuum pump will pump away all the carbon dioxide or aromatic substances in wine, which will affect its flavor.

4, inert gas isolation method

Inert gas isolation method is to pump inert gas such as nitrogen into wine bottles with wine preserver (such as wine preserver) to isolate wine from oxygen. However, some people think that this practice will have a bad influence on the quality of wine, especially on those old wines with insufficient vitality.

The above four methods all reduce the chance or area of wine exposed to oxygen to some extent, but only the refrigerator refrigeration method seems more convenient. Then in practice, we should also pay attention to the use of some tips.

Tips for keeping wine fresh after opening a bottle;

1, remember to cover the wine stopper after each glass of wine is poured;

2. It is best to place the wine bottle upright to reduce the contact area with oxygen;

3. put it in the refrigerator to prevent the temperature difference from being too large.

In addition, we also need to know some special wines, which are particularly sensitive to oxygen. So when we preserve these wines, we should pay more attention to their preservation methods. Such as black Pi Nuo, 8- 10 aged wine, organic wine or sulfur-free wine, and light red wine such as Gehenna, Sangiovese, Zinfandel and Nebiolo.

Teach you how to keep wine fresh after opening and keep it in the refrigerator.

The best way to store wine after opening a bottle is to store it in a water bottle (ordinary plastic bottle), and the size of the water bottle should be just enough to fill the wine up to the bottleneck or top. Seal the water bottle with a lid and put it in the refrigerator. Now you must want to know why not use the original bottle and cork it? This is because once the seal is opened, the cork will give way to the air and enter the bottle, which may destroy the wine.

Store it in a bottle filled with water until there is no room for air to enter at the top. This method can actually store wine for a week, so you must drink it all in this time. When you carry that wine, if you think others may feel embarrassed when you carry the kettle, you can also pour it back into the original bottle. Make sure the original bottle is clean and dry.

Step 2 pump the air out

This is best for red wine. There are many vacuum equipments on the market, among which the most popular one is VAC-U-VIN, which can help you to pump the air out of the bottle. Once you do this, you can seal the bottle and put it in the refrigerator. Please note that many wine lovers do not recommend this method for white wine.

Step 3 put the gas in

A very popular product is called "private preservation", which is produced by ScottA company from California. Farmer invented it. The concept of this product is to spray a mixture of nitrogen, argon and carbon dioxide into the wine bottle, because these gases will form a layer on the wine to prevent oxygen from mixing.

These gases themselves have no smell, so they will not corrode the wine in any way! After spraying the gas, put the cork back on the bottle as much as possible and refrigerate it in an upright position. This will keep your wine in good condition for a few days to a week, depending on the type of wine.

4, big bottles for small bottles

This method is very similar to the first method of using water bottles. If you always seem to have wine left over, I'd rather you buy half a bottle. Although this is not always possible, be sure to store some half bottles of wine, which may help you store the remaining bottles. The best way is to open the cork and pour half the wine into a smaller bottle. Seal the cork, put it in the refrigerator and drink the remaining half. Fill the bottle until the cork makes it difficult for air to enter the wine, so as to keep the cork moist!

Preservation method of unopened red wine

1, build a wine rack

People who like to drink, collect and appreciate red wine art can build a wine rack according to their own preferences. This wine rack is more about displaying red wine. After all, long-term preservation of red wine requires a temperature of 12~ 18℃ and a humidity of 65%~80%. However, it is enough to discharge the usual table wine, and at the same time you can see the artistic accomplishment of the owner.

2, the temperature of the wine cabinet

This is the most cost-effective way to collect red wine in daily life, and the required place is almost 0. About 5 square meters, but the exact size depends on how many red wine bottles you have. When you build this wine cabinet, you can meet the basic conditions for preserving red wine, and the temperature and humidity can be controlled.

3. Professional wine cellar

This method costs a lot of money, but it is very suitable for people who really love and understand red wine. Spend a sum of money to turn the extra rooms and basements in the house into wine cellars with suitable temperature and humidity, and you can also install instruments to control the temperature and humidity, so as to restore the conditions for preserving red wine in the winery. This is the best way to preserve red wine, but it is also the most expensive and troublesome.
