Puer tea is a type of fermented tea originating from the Yunnan province of China. It is made from the leaves of the Camellia sinensis plant and is known for its rich, earthy flavor. Puer tea can be classified into two main types: raw (sheng) and ripe (shou), with the latter undergoing a controlled fermentation process to enhance its taste and aroma. This tea is often aged, and its flavor can change significantly over time, making it a popular choice among tea enthusiasts and collectors. Puer tea is also believed to have various health benefits, including aiding digestion and promoting weight loss.
