If you have uncorked the wine but did not drink it all at once and want to continue to save it, then you need to purchase some useful gadgets to achieve this purpose.

A common type of equipment is a vacuum pump. The air in the bottle can be extracted by using a vacuum pump, but it is not perfect and some air often remains. You can also choose to refrigerate the wine, which will also help slow down the oxidation process of uncorked wine.

People have different opinions on how to identify whether the wine has gone bad, but as a buyer, you need to be clear about the fact that keeping the wine for too long does not mean that drinking the wine will cause discomfort to the body, but it does. The taste will be somewhat unpleasant.

So, the standard for "deterioration" of wine should be judged by your own taste. That is, if you are not sure whether the opened bottle of wine is still drinkable, you can take a small sip first. If you still like the taste, keep drinking it. If you don't, you can choose to throw it away.
