Does Tea Contain More Caffeine Than Coffee?
Tea has only 1/2 to 1/3 as much caffeine as coffee when you compare them cup for cup. In dry form, coffee actually has less then tea in dry form. Next time you brew that pot of coffee, consider how much less your brewed cup of tea will have. Unless of course you consume your tea dry.
What Determines Caffeine Levels?
The amount of caffeine in tea depends on a number of things, the variety of tea leaf, where it is grown, size and cut of the tea leaf, and how you brew or steep as well as how long. Studies from the Caffeine Institute also show that caffeine levels can vary depending on the location of the tea leaf on the plant.
