Thanks for the sample, nannuoshan! This is the third black tea I tried. The dry leaf is dark brown to black in color, thin, and twisty. It smells like malt. I followed the recommended gong fu parameters to brew this tea, but I was able to enjoy a couple more infusions than were listed. The brewed liquor is a nice reddish-brown.
I taste a tiny bit of cocoa, but the flavor seems more potato in nature. I also get a bit of a tang. It is smooth and lightly viscous. Overall, it is clear that each of the three black teas I tried are different enough that one might enjoy all three at different times.
