Puerh is a city used to be the tea distribution centre of the Yunnan Province. As time went by, we regarded the tea from Puerh City as Puerh Tea.
Puerh Tea is a post-fermented tea, there are two types of Puerh Tea:
1) Raw Puerh (naturally fermented)
2) Cooked/Ripe Puerh (process fermented)
Single tree tea means the tea leaves are only from this single tree, so the tea taste must be very pure and powerful.
