My favorite for classic sweet tea is Luzianne. Standard recipe is one cup of sugar per gallon. Best way to brew is make simple syrup, turn off heat, and then let bags steep in it about 4-5 minutes depending upon your taste. Longer than 5 and it tends to turn bitter. Pour over ice, top off with water and then stir.
