Pu-erh tea

„Bĭng: The tea cake itself. Tea cakes or other compressed pu'er can be made up of two or more grades of tea, typically with higher grade leaves on the outside of the cake and lower grades or broken leaves in the center. This is done to improve the appearance of the tea cake and improve its sale. Predicting the grade of tea used on the inside takes some effort and experience in selection. However, the area in and around the dimple of the tea cake can sometimes reveal the quality of the inner leaves.“

„Mr. Gao showed us how to identify gu shu (ancient tree) tea leaves by looking at their texture, rubbing them between your fingers, and eating them raw. Old tea trees produce thicker, more leathery leaves that don’t easily come apart when you rub them. And gu shu buds should be white & shiny. When you chew them, the flavor is very bitter but there is also a strong sweet fragrance, and the juice is relatively easy to swallow. Tai di cha (terrace plantation tea) is also bitter but with a strong, lasting astringency on the sides & front of the tongue, and the juice is harder to swallow.“
