1.5 tsp for 300mL water @95C, steeped four minutes, drunk bare.
I am experimenting with cooler water on black teas, but for this robust blend, I think a full 100C boil does the best job of bringing out the creamy heft of Assam. The smokier (Keemun?) tea dominated and got a little bitter. Very enjoyable, still, and it gave me a great boost this evening.
