If you don't finish drinking it, if you put it in the indoor environment, it will easily stink, and there will be a lot of sour taste in it, which will affect its taste. It is generally better to store it in the refrigerator, which can reduce the contact with some substances in the air, and it will last longer without affecting its taste. But when putting it, it must be upright, not sideways.

You can also pour it into some small bottles and seal it, which will reduce the area in contact with the air and will keep it longer, usually for a few years. But don't use detergent to wash the bottle, the wine will be contaminated, and drinking it is not good for your health. You can also use some vacuum bottles to avoid contact with oxygen as much as possible. These bottles are generally found in many specialty stores. If conditions permit, you can also inject some inert gas to cover the wine and prevent air from entering.

The above is some knowledge about wine. Regular drinking is good for the body. It can make people's skin whiter and delay aging. Usually, you can buy it for yourself, or give it to friends and family. But when drinking, you must do it in the same way as above, it will be less accidental and healthier.
