Why is normal temperature beer not as good as cold beer?

The optimum drinking temperature of beer is 10 to 15 degrees. The reasons why cold beer is better than normal temperature are:

Because beer contains a lot of carbon dioxide and water, the temperature of beer after ice cooling is low, which will make people burp and make people's stomach feel smooth and comfortable. And drinking cold beer in summer has the function of heatstroke prevention and ventilation. At the same time, chilled beer will also reduce the sensitivity of taste organs to bad flavor substances in beer, so people will think chilled beer is delicious.
