Okay, so sweet tea is like regular tea, but it has a lot of sugar in it to make it taste sweet and yummy. We start by brewing regular tea and then add a lot of sugar (like when Mommy makes Kool-Aid). Some people also like to add lemon to their sweet tea to make it taste even better. Sweet tea is very popular in the southeastern part of the United States, especially in places like Georgia and South Carolina. It's often served in big, tall glasses with lots of ice on hot summer days, and people drink it to cool down and feel refreshed.
