I recommend a ratio of 2 to 1 when it comes to leaf and water. 4g leaf, 2 oz water.
It was pretty strong—not overwhelmingly so—but overall AWESOME!
I made sure everything was pre-warmed with very hot water, to control the temps and make sure the tea was actually warm when it was ready to drink! (The teapot had boiled water sitting in it up to the moment I was ready to add the leaf and the cooled water for the tea).
