Why beer is so bitter?

Bitterness is an important taste index that affects the taste of beer. Because the bitterness of beer mainly comes from hops and hop products, the beer has the characteristics of softness and refreshing, suitable bitterness. In addition to reducing the bitterness and astringency of beer in the process, eliminating the factors of uncorrected bitterness and excessive bitterness, and increasing the yield of hop bitter substances; at the same time, it is necessary to keep the taste of beer on the premise of keeping each bottle of beer in the later storage process It can maintain a stable taste and flavor, avoid early aging and peculiar smell of beer, and prevent the degradation of bitterness value. Fresh beer has a soft taste and pure bitterness, but the bitterness value of the beer will change with time or storage changes.
Under normal circumstances, the normal bitterness of beer will disappear quickly, giving people a refreshing feeling after drinking, without leaving bitterness. 

However, in the production process of beer, if the technological conditions are not perfect, the quality of the raw materials is defective, and the process hygiene is poor, the bitterness of the beer will become rough, bitter, and long-lasting. The following are the reasons for the bitter taste of beer.

1. Use spoiled hops
The bitterness in beer comes from hops, and the bitter substance in hops is commonly known as acid. If it encounters factors such as high water content, high ambient temperature, sun exposure, and loose packaging during storage, it will accelerate the oxidative polymerization of a-acid. The bitter substances in the hops will gradually be oxidized and polymerized to become a hard resin with very low bitterness. Therefore, such a beer will have a bitter taste!
2. Excessive additives or improper method of hops
If you add too much hops when brewing beer, the beer will be too bitter. At the same time, the method of adding hops is also very important. Adding hops too early will result in high utilization of bitter substances and unsatisfactory quality of bitterness; if hops are added too late, it will affect the utilization of bitter substances.

3. The water base of brewing beer is too high
Brewing beer with alkaline water dissolves more bitterness and brings bad after-bitterness to beer: brewing beer with brewing water containing higher bicarbonate will not only affect the activity of enzymes, but also make the bitterness of hops rough. Bitterness and astringency are produced.
4. Yeast autolysis
If the yeast is fermented, the external environment is unfavorable or the nutritional content of the yeast is insufficient, it will cause the phenomenon of yeast autolysis. Will make beer produce bitter amino acids, when its content is high, it will bring unpleasant after-bitterness to beer.
In addition to these several reasons for the different degrees of bitterness in beer, there are many factors that can bring different degrees of post-bitterness to beer, such as insufficient boiling strength of the wort, excessive washing of the lees, and failure to separate the wort coagulum. Good, fermentation is not vigorous and so on.

How to reduce the bitterness of normal beer?

1. The first is the choice of beer. Those who do not like bitterness should not use dark beer and other strong-tasting beers at the beginning. The bitterness of this type of beer is relatively heavy. You can choose white beer, refreshing beer, etc., and gradually adapt to beer. The bitterness.
2. In addition to the bitterness caused by different processes and raw materials, beer is also sterilized and non-sterilized. You can drink some draft beer, that is, fresh beer to feel the aroma of beer, and the bitterness will be lessened.
3. The temperature of the beer directly determines the bitterness. Don't drink beer at room temperature because the bitterness will be stronger. If you drink cold beer, the bitterness will be lighter.

4. The method of pouring the wine will also affect the bitterness of the beer. Usually, too much foam in the pouring will affect the taste of the beer, which naturally affects the bitterness. It is recommended not to let too much foam come out.
5. If you really can't accept the bitterness of beer, you can choose to add some sweeter foods like Sprite to beer, or drink sweet beer such as fruit beer directly.
