What is Sweet Tea?

Sweet tea is a popular drink that from the southern United States.

It is a type of iced tea made by steeping black tea leaves in hot water and then sweetening the tea with sugar while it is still warm.

The sweetness of the tea is a defining characteristic of this drink.

It sets sweet tea apart from regular unsweetened iced tea.

To prepare sweet tea, black tea leaves are usually brewed in boiling water for several minutes to extract the flavors and tannins.

Once the tea is steeped, sugar is added to the hot tea and stirred until fully dissolved.

The amount of sugar used can vary depending on personal preference, but sweet tea is generally on the sweeter side.

After sweetening, the tea is allowed to cool, either at room temperature or in the refrigerator, and then served over ice.

Some people like to garnish sweet tea with a slice of lemon for an extra touch of flavor.
