I prefer tea to coffee, but I’ve heard that tea has as much caffeine as coffee. Is that true? I make about two cups of tea from one tea bag. I’ve been reading a lot about caffeine lately.
The caffeine content of a tea bag brewed for five minutes is about 47 milligrams for an eight ounce cup, according to the USDA. Compare that to coffee made from brewed grounds. The caffeine content is about 95 milligrams for an eight ounce cup, depending on the amount of ground coffee added to eight ounces of water. So, tea contains about 50% of the caffeine found in coffee. If you make two cups from one bag, the total caffeine you get will probably closer to 60 milligrams depending on how long you steep the tea bag both times.
