Does Wu Yi tea really cause weight loss? Would any Oolong tea work?

Japanese tea? anyone?

I like just about everything about japan. Does anyone know a good way to make the tea? And can the ingredients/tools to make it be available at walmart?

How can I make good Iced Tea?

I put tea bags in my coffee pot (I don’t drink coffee and got one as a gift) and I put in 9 or 10 but the tea is just too bitter. Is there something different I can do? I used to boil tea bags on the stove, but that can come out bitter too sometimes. What can I do differently to have good Iced tea?
