Not my favorite from the teakruthi samples. The first timed I brewed this I used their instructions and it was a bit weak. The second time I added more leaf and it was still weak, though a bit better than the first time. I don’t taste copper or bitterness, it’s a rather blah cup of tea. Maybe some hints of copper in an aftertaste, but this is not a tea that I would reach for in the morning for a wake me up cup. Now I’m gonna go sip some Assam and get going for the day.
