1. Adding salt to beer will change the taste of beer and let the gas of beer escape.

2. Salt will dissolve quickly after entering beer, which will increase the salt content in beer. There is a certain amount of carbon dioxide in beer, which is dissolved in beer. When the salt content in beer increases, the dissolution of carbon dioxide will decrease, which will lead to a part of carbon dioxide precipitation and overflow in the form of gas, which is what you see as bubbling.

3. Development of beer: Since 1970s, with the success of sterilization, filtration and aseptic packaging technology, pure draft beer that can be preserved for a long time without pasteurization has been developed, which is deeply loved by consumers because of its good taste. In some countries, draft beer accounts for 50% of total beer production.
