2. Pineapple beer should be put back in the refrigerator upright. It is recommended not to put too much at a time. Generally, three or five cans can be put in this way, which can be discharged in order and supplemented while eating, which can prevent the storage time from being too long. Then you can put it on the table for a while when you take it out and drink it. Don't shake the jar hard, because pineapple beer is also a soda drink. If the lid of the tank is opened after shaking hard, the gas will rush out at once, which is easy to cause danger.
