Fermentation is a very important processing step in black tea process, it can Create a unique flavor.

The main reasons why black tea needs to be fermented are as follows:

1. Forming a unique flavor: During the fermentation process, polyphenols in tea are oxidized by enzymes to produce ingredients such as theaflavins and thearubigins, giving black tea its unique color, aroma and taste.

2. Change chemical composition: Fermentation changes the chemical composition of tea, such as caffeine, amino acids and sugars, which improve the taste and nutritional value of black tea.

3. Reduce bitterness: During the fermentation process, some bitter polyphenols are oxidized, reducing the bitterness of the tea and making the tea soup more mellow.

4. Extend shelf life: After fermentation, the water content of black tea is reduced and the degree of oxidation is increased, which helps to extend its shelf life.

5. Promote market diversity: The fermentation process distinguishes black tea from other teas and enriches the varieties of the tea market.
