If you’re looking for a smooth, black tea. This is a good choice.
This is another one by the Spice and Tea Exchange that is available by the ounce in either a pouch or a tin. https://www.spiceandtea.com/Black-Chocolate-Tea
While it has a smooth taste, the flavor profile reminds me of the Sun Tea I used to drink in my childhood when it didn’t have the right about of sugar in it. I will be honest though, most black teas remind me of Sun Tea. The black tea taste is very strong when compared to the chocolate notes of this tea.
