Iced tea is a very popular drink in summer, but does it contain caffeine? And if so, then how much? Many people assume iced tea contains less caffeine than hot tea, but that isn’t always the case.
Iced and hot teas typically contain the same amount of caffeine. The precise quantity varies based on the steeping time, and the type of tea used. Generally, a standard cup (8oz) of iced tea on black leaves contains about 47 milligrams of caffeine (1). A cup of the same size of iced tea on green leaves contains 28 mg per 8-ounce cup (2).
Herbal teas are naturally caffeine-free.

How to Reduce Caffeine in Iced Tea?
Want to reduce caffeine in your drink?
You are in luck! You can decrease the caffeine content in your favorite cup of iced tea using several simple and effective methods.
Adding water to iced tea dilutes the caffeine concentration, which can help reduce its content. Additionally, adding more water will reduce the taste strength of teas, making for a milder flavor overall.
Use Fewer Tea Leaves
Reducing caffeine in iced tea by using fewer tea leaves or fewer tea bags is one of the easiest ways to do so. Adding fewer tea leaves also means that you’ll get a weaker flavor.
Decrease Brewing Time
To make an even milder cup of iced tea, try decreasing your brewing time.
Use Decaf Tea
Using decaf tea as a base is also an option for those who want iced tea without worrying about high caffeine levels.
Make It Herbal
Herbal teas have many health benefits, such as improved sleep patterns and reduced stress, due to their calming properties. These teas are often rich in antioxidants, promoting immune health, and can aid digestion. Switching to herbal teas can also potentially alleviate tinnitus symptoms in some individuals, although more research is needed.
