The mold you find on a Pu-erh should be a white
one, not a black one!!! Different mold can
develop on a Pu-erh when it is placed in
different environment. Some are good, some are
BAD. The good apsergillus we Chinese talk about
is NOT aspergillus niger. Not a black mold!
It is believed that a Pu-erh has to go through
the process of developing white mold, then
letting it disappear. Only after a Pu-erh gone
through the whole process, it is considered
completely aged.
The correct process for aging a Pu-erh:
Green Pu-erh, let it ages naturally. Storage
room is the key to the aging. Experienced Pu-erh
vendor knows the value of a dry old stroage
room. It is normally guarded. I am not kidding.
Wo Dui processed (or black Pu-erh but not
includes those wet storaged ones) Pu-erh, loose
teas were first go through the Wo Dui process
(scientifically speedy aging), then compressed.
Only a few large factories know the real
process. If you are not familiar with the
factory on the label, you are better off stay
with green Pu-erh. BYW, the import/export
company Pu-erh bing cha is a product of Cha Yuan
(Tea Garden) group. Improperly processed pu-erh
can be harmful to your health. You may visit the
