Black tea is loved by tea lovers because of its bright soup color, mellow and sweet taste, and fragrant flowers and fruits, which also makes the process of drinking tea full of comfort for tea lovers. However, if the brewed black tea does not have the original floral and fruity aroma, and does not have the sweet and sweet soup feel, but is replaced by a sour and sour taste, it will greatly affect the tea farmers' sales of tea and the reputation.
The possibility of black tea sourness is divided into three types: improper black tea production process, improper storage, and improper brewing. You can analyze them one by one, find out the possibility of black tea sourness one by one, and solve the problem from the source.
Among the reasons for the sourness of black tea soup, the improper black tea process is the most common reason. The red packet production process is roughly divided into four steps, first withering, then rolling, then fermentation, and finally drying.
This process and steps all have extremely high requirements on temperature, humidity, ventilation, etc. If there is a little error in the details, it is likely to cause "improper fermentation" and the tea soup will become sour.
Next, I will analyze and provide solutions for you one by one.
