Pu'er tea is mainly produced in Kunming City, Chuxiong Prefecture, Yuxi City, Honghe Prefecture, Wenshan Prefecture, Pu'er City, Xishuangbanna Prefecture, Dali Prefecture, Baoshan City, Dehong Prefecture, Lincang City, etc. 11 Part of the prefecture, the current administrative area is the protection scope of Pu'er tea geographical indication products.

Using Yunnan large-leaf sun-dried green tea within the scope of geographical indication protection as raw material, and using specific processing techniques within the scope of geographical indication protection, tea with unique quality characteristics, according to its processing technology And quality characteristics, Pu'er tea is divided into two types: Pu'er tea (raw tea) and Pu'er tea (cooked tea).

According to research, the tea produced in Yinshengcheng is a Yunnan large-leaf tea species, which is also a Pu'er tea species. Therefore, the tea produced in Yinshengcheng should be the ancestor of Pu'er tea.

Therefore, Ruan Fu of the Qing Dynasty said in "Pu'er Tea Records": "Pu'er belonged to Yinsheng Prefecture in ancient times. The use of Pu'er in Western Tibet has been since the Tang Dynasty." Li Shi of the Song Dynasty said in his "Continuation" The book Natural History also records: "Tea comes out of the mountains, and it is collected from time to time. It is mixed with bean sprouts and ginger, cooked and drunk."

In the Yuan Dynasty, there was a place called "Bu Ribu", because it was later written The Chinese character became "Pu'er" (at that time, "Er" did not have three dots of water, the word Pu'er was first seen here, and the name was corrected and written into history.

Yunnan tea without a fixed name is also called "Pu'er tea" gradually became a necessary commodity sold in markets in Tibet, Xinjiang and other regions, and the word Pu'er tea became famous at home and abroad. It was not until the end of the Ming Dynasty that it was called Pu'er tea.

Historical documents record that the first person to cultivate Pu'er tea was Fan Chuo, an official of the Tang Dynasty. In the seventh volume of his book "Manshu", it is said that "tea comes out of the mountains around Yinsheng City, and there is no way to harvest it." "The Mengshe people cooked it with pepper, ginger and cinnamon."

According to research, the tea in Yinshengcheng should be Yunnan large-leaf tea, which is also Pu'er tea. Historical records show that as early as 1100. Many years ago, Sipu District, which belongs to the "Yinsheng City Boundary Mountains" in Nanzhao, was rich in tea.

The historical development of Pu'er tea can be divided into several stages:

First. In the first stage (Tang and Song Dynasties), the Central Plains has entered the group cake tea stage, while Yunnan Pu'er tea is in a period of free development without harvesting and production methods.

The second stage (Yuan, Ming and Qing Dynasties) is the Central Plains tea culture. Under the decree of Emperor Taizu of the Ming Dynasty, a huge change took place, but the production of Pu'er tea developed faster due to the main sales groups being ethnic minorities in the border areas and the need for long-distance transportation (to Tibet).

As Pu'er tea was favored by the Qing court due to tribute, this period was the Pu'er tea stage in the true geographical sense.

The third stage (since the late Qing Dynasty). That is the modern Pu'er tea stage. Modern Pu'er tea processing technology has sprouted, and a social pattern of multi-tea production has emerged.

Since the late Qing Dynasty, Pu'er tea in the traditional historical and geographical sense has withdrawn from the historical stage. The first reason is that in the late Qing Dynasty. Since then, Pu'er has gradually lost its status as a tea processing and distribution center. Changes in administrative divisions have broken down the original Pu'er tea area into Simao, Mengla, Menghai, and Jinghong tea areas, and tea is no longer labeled as Pu'er.

II. With the advancement of processing technology, tea in the original Pu'er tea area has diversified into black tea, roasted green tea, sun-dried green tea, fried green tea, etc. Third, the ancient Pu'er tea mountains have gradually declined and been replaced by emerging tea areas.
