In a large pot, bring 4 cups of water to a rolling boil.

After turning off the heat, add the tea bags to the pot. Steep for 5-7 minutes, depending on how strong you like your tea.

Remove the tea bags, ensuring not to squeeze them, which can make the tea bitter.

While the tea is still warm, add 1 to 1 ½ cups of granulated sugar. Stir until all of the sugar has dissolved.

This step is crucial for achieving the smooth, sweet taste characteristic of Southern sweet tea.

Add the sweetened tea to a gallon-sized pitcher.

Fill the remainder of the pitcher with cold water, adjusting the amount to taste.

Refrigerate until chilled, about 1-2 hours.

Serve the sweet tea over ice.

Garnish with fresh mint leaves or lemon slices, if desired.
