The difference between black tea extract and Pu'er tea extract:

1. Different types. Black tea belongs to basic tea. The basic tea categories include green tea, black tea, green tea, yellow tea, white tea and black tea. Pu'er tea is a kind of reprocessed tea. Pu'er tea is made of sun-dried green tea (green tea) and processed by special technology.

2. Black tea belongs to full-fermented tea and Pu'er tea belongs to post-fermented tea. Black tea is good for new tea, and Pu'er tea is good for many years (within a range of course). In terms of production technology, black tea is fermented first, and fermentation stops at the end of production; while Pu'er tea is post-fermented tea, it will be fermented naturally all the time during storage, even the ripe tea fermented artificially will continue to ferment. So Pu'er tea can be divided into raw tea and ripe tea, but black tea can't.

3. Pu'er Tea refers to the large-leaved sun-dried green tea in Yunnan. There are many kinds of black tea in China, such as Rizhao black tea, Qihong, Zhaoping red, Huohong, Yunnan red, Yuehong, Quancheng red, Quancheng green, Suhong, Sichuan red, Yinghong, Chuyunxian black tea in Dongjiang, especially Qimen black tea.
