Puer Tea Glossary - Zhi Zheng Tea Shop

„ku se; 苦涩 - Bitter and astringent. The nature of new raw Puer is a little astringent and bitter, followed by a sweet aftertaste. However, a bitterness with no sweet aftertaste is not typical of Puer and an astringency which is not comfortable would not be considered good tea. “
