An Cha is something like Pu'er but made with An Hui's tea. Kind of nice when you follow the process mentally - good flavor of Qi Men area tea leaf (in the same area as Qi Men Red), compressed, wrapped in bamboo leaves (An Hui produces a lot of tea, and bamboo as well) so the tea takes on a trace of bamboo flavor, fermented to bring flavor to a higher level, then put in a traditional bamboo basket. Quite a nice and natural idea.

Suggested brewing parameters - TEA:WATER (by weight) 3:100. Gaiwan is the most convenient tool. Tea in gaiwan, then 90C water. 1 min per brew but you can leave the tea in the gaiwan if you don't pour it out into other cups to drink. A longer (or much longer) brew time won't hurt because An Cha is quite Pu'er-ish. Can last 3-5 infusions.
