Query: Yummy!

This is an excellent black tea. My preference in black teas runs toward those that are smooth and not at all bitter. This means I often end up with somewhat blander brews with little to distinguish them. This Ntingwe Kwazulu is a great exception to that experience. It's quite brisk, has robust flavor and yet is very smooth with no bitterness. My only complaint is the powder residue in the bottom of the cup, but it's well worth it. Now my favorite black tea!
