Pu-erh tea

„Nèi piào (内票): A larger description ticket or flyer packaged loose under the wrapper. Both aid in assuring the identity of the cake. It usually indicates factory and brand. As well, many nèi piào contain a summary of the tea factories' history and any additional laudatory statements concerning the tea, from its taste and rarity, to its ability to cure diseases and effect weight loss.“

„The recently developed Wo Dui process (渥堆) pioneered by both the Menghai and Kunming Tea Factories has created a new type of pu-erh tea of which some traditionalists dispute the legitimacy. This process involves an accelerated fermentation into "ripe" Shou Cha (熟茶) which is then sold loose or pressed in various shapes.“
