We can save the red wine in the following three ways.
1. Refrigeration
For wine, oxygen is like a double-edged sword. On the one hand, wine needs oxygen to gradually develop complex aromas; on the other hand, too much oxygen can cause wine to deteriorate. Therefore, when handling opened wine, be sure to avoid excessive contact between the wine and oxygen. Like other foods, wine can be kept in the refrigerator. In a low-temperature environment, wine is not as prone to chemical reactions, so wine is not susceptible to oxidation. In addition, low temperature can inhibit the activity of acetic acid bacteria, thereby effectively preventing the vinegar of wine.
2. Change the bottle
For ordinary bottled wine (750ml), if half of it is left, the best way at this time is to find a wine bottle with a capacity of 375ml , then pour the wine into the small bottle, re-cork it, and put it in the refrigerator. Because it is difficult for air to get into a full wine bottle, this can better prevent the wine from coming into contact with oxygen. However, it should be noted that small-capacity wine bottles must be cleaned to avoid contaminating the wine.
3. Vacuum treatment
If you want to further prevent the oxidation of wine, you can consider using a vacuum pump. The specially designed vacuum pump is equipped with a rubber stopper and an air extraction rod. When inserted into the wine bottle and pressed gently, the air in the bottle will escape. Vacuum pumps are very practical and relatively affordable, and can be found in many large supermarkets. Of course, the degassed wine still needs to be placed in the refrigerator to ensure the freshness of the wine.
