Bottled wines have a shelf life of up to 30 years and as short as 5 years. Once a bottle of wine is opened, it is best to drink it within 3 days. Home-brewed wine is best consumed within a year. The taste will become lighter over time, but it will not harm your health.

1. The best drinking period of white wine and rosé wine is within 1 to 3 years. Red wine should be aged after 3 years, but older is not always better. Because wine is not liquor or other foreign distilled spirits such as brandy, vodka, gin, Langmujiu, etc.

2. The cork of opened wine should be put back, and the bottle should be placed in the refrigerator and placed upright; usually white wine can be stored in the refrigerator for 1 week after being opened; red wine can usually be stored in the refrigerator after being opened. Store in the refrigerator for 2-3 weeks.

3. No matter how good the quality of wine is, if it is not stored properly, it will easily age or even deteriorate. Generally, a cool, constant temperature, well-ventilated, dark, and odor-free place is the most ideal environment for storing wine. In addition, when storing wine sealed with cork, the wine should be tilted downward or placed lying down. This can ensure full contact between the cork and the wine and prevent the cork from drying out and causing air to enter the bottle and accelerate the oxidation of the wine. Extended information

The best temperature for wine storage:

1. Usually the best temperature for wine storage is 10°C. Generally speaking, the temperature between 7 and 18°C ??is also There will be no harm. Try to avoid temperature fluctuations in the wine cellar: unstable temperatures will have a certain impact on the quality of the wine. Try to avoid long-term storage of wine above 20°C, nor below 0°C, as this will cause the wine to accumulate stones, thereby reducing the acidity of the wine.

2. It is best to keep the temperature at which wine is stored constant, and short-term temperature fluctuations need to be avoided as much as possible. Generally, the higher the temperature, the faster the wine matures; when the temperature is low, the wine will grow slower.

3. Temperature is the most important factor in wine storage. This is because the taste and aroma of wine can best evaporate at the appropriate temperature. To be more precise, the most comfortable feeling will occur during the evaporation of alcohol. If the temperature of the wine is too high, bitter, sour and other flavors will come out; if the temperature of the wine is too low, the aroma and delicious taste will not be effectively evaporated.

4. Each type of wine needs to be stored for a period of time before drinking. The exact time depends on the balance between freshness and aroma. This does not mean that wine that has been aged for a long time can be drunk with confidence, because the storage of wine also has a limit.

5. Of course, the changes in ripening speed also vary with the grape varieties and brewing methods used in winemaking. Generally speaking, the optimal storage temperatures required for different wines are as follows:

Semi-sweet and sweet red wines 14-16℃; Dry red wines 16-22℃

Semi-dry Red wine 16-18℃, dry white wine 8-10℃

Semi-dry white wine 8-12℃, semi-sweet and sweet white wine 10-12℃

Brandy? Below 15℃ Champagne (sparkling wine) 5-9℃
