1, pour a large bottle of wine into a small bottle, fill it as full as possible, and then block the bottle with a cork.
2. Divide the unfinished red wine into small bottles, cover the bottle cap tightly, put it in the refrigerator, and finish each bottle as soon as possible.
3. Pump the air out of the bottle, then put it back into the cork and put the bottle upright in a cool and ventilated place.
In addition, the optimum storage temperature of red wine is 10℃- 15℃. If stored above 25℃, red wine will lose its delicate taste, and what's more, it will taste like cooked wine. If the temperature is too low, the wine will swell, the wine will overflow and the cork will be pushed out of the bottle mouth, which will lead to the oxidation of the wine and the growth of bacteria.
Extended data:
Long-term preservation of red wine needs attention:
1. In order to ensure constant temperature storage, the ideal storage temperature of general wine is 10- 15℃. Too cold will make wine difficult to ferment, and too hot will easily oxidize.
2, constant humidity storage, the ideal storage humidity is between 65% and 76%, too dry air is more likely to enter the bottle and too wet cork is easy to mold and breed bacteria.
3, avoid light preservation, light is easy to guide wine deterioration. The fourth is to ensure the ventilation of the storage area and the surrounding environment, without peculiar smell, which can make the wine more delicious, so we must pay attention to the surrounding environment of the wine.
