Pu-erh tea

„Ripened or aged raw pu-erh has occasionally been mistakenly categorised as a subcategory of black tea due to the dark red colour of its leaves and liquor. However, pu-erh in both its ripened and aged forms has undergone secondary oxidization and fermentation caused both by organisms growing in the tea and free-radical oxidation, thus making it a unique type of tea. This divergence in production style not only makes the flavour and texture of pu-erh tea different but also results in a rather different chemical makeup to resulting brewed liquor.“

„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.“
