How to store opened wine?

Refrigerator preservation Like other foods, wine can be preserved by keeping it in the refrigerator. In low temperature conditions, the chemical reactions take place more slowly, making the oxidation process slow as well. Lowering the temperature of the wine is also a way to prevent the effects of fermenting bacteria that make the wine sour.

Therefore, putting the opened wine in the refrigerator is one of the important steps to keep the wine delicious for the next time you drink it. There are also other ways of preserving wine by reducing the effects of oxygen directly. Pour less wine into another smaller bottle and then store it in the refrigerator. According to the experience of regular wine drinkers, a single drink that is just right for the mouth and not harmful to the liver is only ½ 750ml bottle at most. So, before drinking, you should drain half a 750ml bottle of wine into a 375ml bottle, close the cork, and then put the small bottle in the refrigerator before drinking.

Because practice shows that doing so the amount of air between the surface of the wine and the cork is very small. Vacuum Vacuuming is also a way to prevent alcohol from coming into contact with oxygen. Place the specially designed rubber stopper in the neck of the bottle and then use the pump to suck out the air. If comparing between wine that is poured into small bottles and wine preserved by vacuum, wine preserved by vacuum is less flavorful, bland and stale.

There are two main reasons:

First, when pumping out the gas, it will create bubbles that float on the surface of the alcohol, causing carbon dioxide gas to decompose due to reduced pressure. Changing the composition of the wine makes the wine more bland and less enjoyable.

Second: The taste of the wine is evaporated and the taste of the wine is lost. Nitrogen gas injection Rapid injection of compressed nitrogen gas into the alcohol to reduce oxidation. It sounded like the ideal solution, both without evaporating the flavors and minimizing the alcohol's exposure to oxygen when nitrogen was injected.

But unfortunately, nitrogen gas can have a damaging effect on wine, especially for mature and strong wines. For sparkling wines The above ways of preserving wine are not suitable for sparkling wines. Because if you pour less wine into a smaller bottle to preserve it, it will lose all the gas. The carbon dioxide layer of the bubble has protected the wine from oxidizing, so preserving the wine by injecting nitrogen gas is not necessary. So for sparkling wine, it is only necessary to close the cork and store it in the refrigerator without fear of losing the unique characteristics of the wine. The inhaler should be used to adjust the pressure inside the bottle when opened. Doing so helps preserve the gas. In general, most wines should only be left for the next day. Because, the above methods of wine preservation are only ways to delay the time of wine spoiling, not a way to prevent wine from spoiling. Although there are many ways to preserve, experience shows that before using, it is advisable to estimate the amount of wine consumed at that meal, then pour the remaining amount into a smaller bottle, close the cork and put it in the refrigerator is the best way to preserve wine. Note: Take the wine out of the refrigerator a few hours before use.
