Green Pu Erh is a type of fermented tea that originates from the Yunnan province in China.
It is made from the leaves of the Camellia sinensis plant, which are harvested, dried, and then aged for several years. Unlike other types of tea, Green Pu Erh undergoes a process called "post-fermentation," which means that the tea leaves are allowed to ferment after they have been dried and processed.
This gives Green Pu Erh its unique flavor, which is often described as earthy, mellow, and slightly sweet. It is also known for its health benefits, including improved digestion and weight loss.

It is believed that green Pu-Erh tea was first developed in the Yunnan province of China during the Qing Dynasty (1644-1911). Also It is unknown who specifically invented green puerh tea. Puerh tea has a long history dating back to ancient China, and the production of green puerh tea likely developed over time as a way to preserve the freshness and flavor of the tea leaves.

No, Pu Erh tea is not a green tea. It is a fermented and aged tea that is traditionally produced in the Yunnan province of China. It has a distinct earthy and woody flavor and can be enjoyed both as a young tea or as an aged tea that has been stored for several years. Green tea, on the other hand, is unfermented and is characterized by its fresh and grassy flavor.
