Pu-erh tea

„Depending on the desired product and speed, from quickest and tightest to slowest and loosest, pressing can be done by a hydraulic press, which forces the tea into a metal form that is occasionally decorated with a motif in sunken-relief. Due to its efficiency, this method is used to make almost all forms of pressed pu'er.“

„Good quality old tea has a 'matured' fragrance (chen wei). This comes from tea that has been stored well and matured without any adverse effects. (xing wei - a 'fishy' smell that can be detected in old tea that has been stored poorly - should be clearly distinguished from chen wei which is quite different). “
