I recently tried the two Upton East Frisians and this one. For me the Upton BOP blend was a winner by a long shot. I had to reduce the temperature and brew time from the standard recommended by Harney & Sons (they recommend 212/5 min for all black teas) or it was bitter. Once that was taken care of, I just didn’t care for the taste of the tea.
