I think I got this one figured out finally. I lowered the steeping time by about 1 minute. This time it did not have the harsh, bitter, in your face taste it had the first time I tried it. I used the same amount of sugar, but did add a splash of whole milk (thanks to my 2 year old daughter) and this now is one of my go to teas when I don’t have the space or time for loose leaf tea.
