Pu-erh tea shapes

„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.“
