When many wine lovers drink wine, the common thorny problem is to open a bottle of red wine and not finish it all at once. What should I do with the rest of the wine at this time? How long can't I drink red wine after opening it? Is the reason why red wine can't be drunk because the taste or quality has changed? When these things happen, you must first have an idea that wine, like other fresh fruits, vegetables and meat, will rot quickly under normal environment and temperature. If stored in refrigerator or low temperature environment, the time of wine decay may be prolonged, but it may be less optimistic to keep the original freshness.

In fact, once the wine is opened, it will be exposed to the air. Unless there is the bottle sealing technology and equipment of the winery, the wine quality and taste will only gradually weaken and go from bad to worse. A large amount of oxygen immediately oxidizes the wine, even if the original cork or vacuum wine stopper is used to block the bottle mouth of the wine, it can not prevent the grapes from rapidly oxidizing and declining, and the only way out for the wine is to go bad.

The reason is that once the wine comes into contact with air, although the bottle mouth is blocked by various methods, there is still a lot of oxygen in the bottle, and oxidation is still going on. Therefore, whenever you encounter endless wine, the expert's advice is that whether it is stored in a special thermostat or a household refrigerator, there is no guarantee that it will not go bad or deteriorate.

Ordinary liquor should be drunk as soon as possible within 24-36 hours, and liquor with good liquor quality can only be drunk for 24 hours. The general form of red wine can last for about 72 hours, but some special red wines can last for more than a week. Although they have not gone bad, they will change the smell of wine more or less. Once the taste of wine changes, the freshness is gone, and it always feels less comfortable than the wine just opened. Even if you put the thermostat back, it won't help, and it still can't save the gradual decline. However, this situation is not absolute, and there will be exceptions.

Before placing the opened wine, you can put the cork back into the bottle mouth, or replace the original cork with a vacuum cork. The bottle should be upright, which can reduce the contact surface between wine and air. If the bottle is placed horizontally, it will accelerate the taste or deterioration of the wine. The above suggestions are only to slow down the taste or deterioration of wine, and the best way is to drink it all at once. If you have the habit of cooking western food, you can use it as wine or Chinese food.

It is difficult to import wine that has deteriorated due to excessive oxidation, but it just goes bad. If wine goes bad, it even smells unacceptable. Personally, in this case, it is necessary to reluctantly discard it. Thrift and barely drinking bad wine are two different things. If it causes physical discomfort, it is not good. Next time you drink, try to estimate your drinking capacity and reduce the remaining wine, so that you won't brew too much stale or deteriorated wine again and again.
