I wouldn't say earl grey was a "light" flavor. It's pretty heavy and peppery to me.

I got a rooiboos with vanilla tea that tastes basically like the cakes I used to make in my EasyBake oven. noooooom

anyway, I'm not English, but I have the understanding that the temperature at which you should steep tea depends on the tea. The English do have a reputation for ah.. cooking the taste out of foods
