Take the cup full of cold water and boil it (in the microwave). Or fill the cup about 2/3 full with boiling water if there is a coffee machine that dispenses hot water. Then add the tea bag (I would use 2-3 bags for that much water). Then fill the rest of the way with ice.

I just steep the tea bags 1 tea bag foe 8oz of water for about an hour. Add sugar and lemon to taste and chill

I usually just heat about a cup of water in the microwave until nearly boiling, toss in a tea bag or two (depending on how strong I want it) and let it sit for a while (anywhere from 15 minutes to 2 hours - I sometimes forget *oops*) and then pour the brew into a gallon or so of cold water.

I don't like sugar in my tea, but if you do, I'd suggest adding it to the hot/warm brew because it dissolves better like that than in cold water.

My husband always makes our tea in our coffee pot. We don't drink coffee...so we make tea instead. He puts 4 tea bags in where the coffee grains would go. And he puts about 3 cups of sugar in the pitcher with the hot tea. Hope this helps.

My usual method is to boil a 4-cup measuring cup of water in the microwave for 4 minutes. Then I put in 2 of the family size tea bags and let it steep for about 15 minutes. I then pour that into a 2 gallon (I think!) pitcher and fill the rest with cold water. Perfect.
