Pu-erh tea

„The piling, wetting, and mixing of the piled máochá ensures even fermentation. The bacterial and fungal cultures found in the fermenting piles were found to vary widely from factory to factory throughout Yunnan, consisting of multiple strains of Aspergillus spp., Penicillium spp., yeasts, and a wide range of other microflora. Control over the multiple variables in the ripening process, particularly humidity and the growth of Aspergillus spp., is key in producing ripened pu'er of high quality.“

„Pu-erh shape - Melon, or gold melon - Its shape is similar to tuóchá, but larger in size, with a much thicker body decorated with pumpkin-like stripes. This shape was created for the famous "Tribute tea" (貢茶) made expressly for the Qing Dynasty emperors from the best tea leaves of Yiwu Mountain. Larger specimens of this shape are sometimes called "human-head tea" (人頭茶), due in part to its size and shape, and because in the past it was often presented in court in a similar manner to severed heads of enemies or criminals.“
