Puer Tea Glossary - Zhi Zheng Tea Shop

„ping wen; 平稳. Smooth, steady, even. Used to refer to the taste of tea. Puer should be smooth and steady without any sudden changes in the flavour as steepings progress. A sudden change or loss of flavour is an indicator of poor quality. Good Puer can be steeped 20 to 30 times and maintain it's flavour. “

„Astringency
Astringency invariably accompanies bitterness. In some Puer the astringency is more pronounced, the bitterness slightly weaker. A benefit of astringency is that it can help promote salivation. If this is felt on the underside of the the tongue it is a further mark of good tea.“
