In my hands right now I've got ... well, my keyboard. But next to my keyboard is a freshly brewed pot of Yunnan Gold in my Meguro teapot.
A heaped tablespoon of tea, 15m of steeping. Yes, 15.
EDIT: To be precise, I have this problem with all the teas I have - Yunnan Gold being the most pronounced. I also have Rooibos Vanilla (1tbsp, boiling, 6m); Earl Grey (1tbsp, boiling, 6m); and Golden Monkey (1tbsp, boiling, 4m)
