After fresh tea leaves are picked, they are naturally stored without undergoing the fermented processing of dark tea, and this is called raw tea. The nature of raw tea is relatively strong and stimulating. Newly made or not long stored raw tea has a strong bitter and astringent taste, and the soup color is relatively light or yellow-green. Raw tea is suitable for long-term storage at home. Year after year, watching the color of Sheng Pu'er leaves gradually deepen, the flavor becoming increasingly mellow, and the soup color gradually turning red brings indescribable joy and excitement. Of course, the value of Pu'er also increases year by year.
