I drank this the other day.
When I saw the label, "Shimanto Red", I thought it was Rooibos tea, but when I read the label I realized it was a straight black tea.
Shimanto is an area in Kochi prefecture. Apparently there are many tea farms there.
This tea is smooth and I am glad they add no sugar to it.
I noticed on their website that they also have a Royal Milk Tea version, so I'll be keeping my eye for it around here.
