Pu-erh tea

„To produce pu'er, many additional steps are needed prior to the actual pressing of the tea. First, a specific quantity of dry máochá or ripened tea leaves pertaining to the final weight of the bingcha is weighed out. The dry tea is then lightly steamed in perforated cans to soften and make it more tacky. This will allow it to hold together and not crumble during compression. “

„Black Puerh Tea was invented by Kunming Tea Factory in 1972/73 and was manufactured in Xia-Guan Tea Factory ever since 1976. It is now manufactured in many different factories and is by far the most popular type of puerh sold.“
