Gunpowder tea
Gunpowder tea (珠茶; pinyin: zhū chá) is a form of green Chinese tea produced in Zhejiang Province of China in which each leaf has been rolled into a small round pellet. It is believed to take its English name from the fact that the tea resembles grains of black powder. This rolling method of shaping tea is most often applied either to dried green tea (the most commonly encountered variety outside China) or Oolong tea.
