Yiwu Mountain, Yunnan Province. This tea is from one of the most famous Pu'er producing mountains, Yuwi, complex and fragrant. Aged since 2015, it has no astringency yet still very strong Qi. I would recommend to drink this tea earlier in a day because of it's uplifting powerful effect on the the body. Strong stimulant, it will help you to move mountains if you need to.
