Pu-erh tea

„Once dry, maocha can be sent directly to the factory to be pressed into raw pu'er, or to undergo further processing to make ripened pu'er. Sometimes Mao Cha is sold directly as loose-leaf "raw" Sheng Cha or it can be matured for 2–3 years in loose leaf form due to the faster rate of natural fermentation in an uncompressed state. This product is then pressed into numerous shapes and sold as "raw" Sheng Cha as a more matured final product.“

„Pu-erh shape - Tuocha, Bowl, or Nest - A convex knob-shaped tea, its size ranges from 3g to 3 kg or more, with 100g, 250g and 500g being the most common. The name for tuocha is believed to have originated from the round, top-like shape of the pressed tea or from the old tea shipping and trading route of the Tuo River.[16] In ancient times, tuocha cakes may have had holes punched through the center so they could be tied together on a rope for easy transport.“
