What is the satin of Tieguanyin when looking at the bottom of the leaf?
After Tieguanyin is brewed, the bottom surface of the leaves looks like velvet fabric, but it has satin-like luster and feel. Satin effect is usually thicker at the bottom of leaves. But it is different from the bottom of the old leaves. Satin leaves are elastic and old leaves are stiff and dull. Satin effect is one of the characteristics of good tea.
