Pu-erh tea comes from China, it's also known as "Red Tea" and is one of the distinct types of tea, the others being Black, Green, White and Oolong. They all come from the same plant, the difference being in how they are prepared, the end result too is a different taste for each. Black and Pu-erh teas are both fermented, the Pu-erh becomes a coppery red. Quite an interesting flavour, more earthy than the others. This box comes from Kowa Coffee and Tea Company.
