Malty is a good way to describe it.
I accidentally discovered this one pairs amazingly well with chocolate-covered biscuits. Did someone say "malty"? Oh yeah. Together with chocolate-covered biscuit, a sip of Yunnan Black gives a rich and malty flavor that is as delightful as it is surprising. Very addicting! It's my favorite self-care treat on my days off. Try this tea! You won't be disappointed.
