I might be weird, but one of my favorite teas is Gen Mai Cha (sp?) over ice. If it is cold outside, I drink it hot and it is really good too.
To make my ice tea, I use a recycled glass bottle. A wide mouth bottle is the best. I fill the bottle with fresh clean water and put in 3 or 4 tea bags depending on what kind I'm making. The bottle is then left in the sun until it looks dark enough, or can be left in the fridge over night.

For hot tea, at work we have a hot water spigot, but I don't know the temp. At home, I drop the tea into a cup of just boiled water.
