For tea farmers, the black tea processing sometimes has a bitter and astringent taste, which reduces the quality of black tea and reduces sales. Black tea is fully fermented tea. If some black teas are found to have a bitter taste, then we must first know what substances cause the bitterness of tea.
Astringency: The main component is polyphenols.
Bitterness: The main components are caffeine, anthocyanin and tea saponin.
Based on this, we judged that the bitter taste of black tea is because there are too many polyphenols and caffeine in the tea soup. In fact, the content of polyphenols in black tea is relatively low in the six major tea categories. The main reason is that with the increase of fermentation degree, the content of tea polyphenols will decrease. When black tea is fermented, tea polyphenols are enzymatically oxidized into theaflavins and thearubigins, and the content of tea polyphenols will eventually decrease by more than 90%. Therefore, under normal circumstances, the bitterness of black tea is very low.
I tried to brew it for a while. If the soup is out for more than 30 seconds, it does feel bitter and sour. Obviously, this is one reason, that is, the problem caused by the wrong method of brewing the tea-the water temperature is too high and the brewing time is too long, which will lead to bitterness. degree increase.
Now that we know the origin of the bitterness, is there any other situation? Studies have shown that the production process of black tea and the material of the tea will have an impact.
