Although some wines with a good base will have a floral aroma even if they are slightly popped, if there is no fresh fruit aroma, it means that the wine is not good. fresh.

What are the usual reasons for a burst?

1. When the wine is bottled, the cork is not pressed tightly due to the problem of the machine, which will cause the cork to stay outside the bottle, which looks like a "cork burst", but it is not actually a cork burst.

2. Wine contains high sugar and yeast, which will form secondary fermentation, resulting in the release of carbon dioxide, or the use of sulfur dioxide in the fermentation process will also produce carbon dioxide, when the temperature rises, the solubility decreases, which is easy to cause Burst.

3. If the wine is shaken violently, it will easily lead to accelerated oxidation and evaporation of phenolic substances in the wine, and at the same time increase the temperature in the bottle, which will also easily lead to cork bursting.

4. The temperature is high in summer, and usually the wine is particularly easy to pop when placed in the trunk of a car.

The wine after corking does not mean bad wine, it depends on whether it can continue to drink. If the cork bulges slightly, it may be caused by the vibration during transportation. The body of the wine is not greatly affected, and it needs to be drunk as soon as possible. If the cork protrudes a lot, and there are obvious wine stains on the wine label, it means that the wine has been greatly affected, and it is not recommended to drink it.
