Uhhh I think it’s just tea that is specifically for cold tea. Orange Pekoe and Pekoe cut black tea leaves are the typical ones used or a blend. I just keep a measuring cup in the sugar canister that I know how many of them I have to put in the pitcher to make sweet tea. The hardest thing is just opening all the tea bags (I use two luzianne decaf bags and 3 Moroccan mint bags to make spearmint sweet tea)
