Pu-erh tea

„Wo Dui - this new process produced a finished product in a manner of months that many thought tasted similar to teas aged naturally for 10–15 years and so this period saw a demand-driven boom in the production of Hei Cha by the artificial ripening method. “

„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.“
