Pu-erh tea

„Wrapper: Made usually from thin cotton cloth or cotton paper and shows the tea company/factory, the year of production, the region/mountain of harvest, the plant type, and the recipe number. The wrapper can also contain decals, logos and artwork. Occasionally, more than one wrapper will be used to wrap a pu'er cake.“

„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). “
