Bring 4 cups water to a boil: pour over tea bags. Cover and steep 10 minutes; discard tea bags.
Bring remaining 8 cups water and sugar to a boil in a large saucepan, stirring constantly; boil 5 minutes. Remove from heat; stir in tea, lemon juice, and extracts. Chill. Serve over ice; garnish, if desired.
This was delicious, and even pretty! It reminds me of a recipe my grandmother would make for parties--very special and out-of-the-ordinary. Everybody wanted the recipe!
