Iced Tea is a popular beverage made by brewing black tea and then adding additional water and ice.

Some may choose to also add sugar, lemon, or other sweeteners before drinking. However, this doesn't change the caffeine content by much since these ingredients would only add slightly more volume to the drink.

Caffeine in iced tea can vary due to several factors.

  • Amount of tea bags used
  • Amount of water added
  • Amount of ice added
  • Type and quality of tea used
  • Steeping time

The above caffeine amount reflects 8 floz of brewed tea before adding ice. Also the tea bag to water ratio of 1 tea bag per 8 floz. of water. 

Iced tea can also be made using other teas such as green tea and white tea. The caffeine content of these iced teas will generally be lower.
