I’ve heard that tea has more caffine than coffee but then why is coffee typically used to keep you awake? Does coffee have more energy value or something? Which is more effective tea or coffee?
I don’t know where you heard that teas have more caffeine than coffee, but that is wrong:
**8-ounce Beverage milligrams** Coffee, Drip 115-175 Coffee, Brewed 80-135 Coffee, Espresso (2 ounces) 100 Coffee, Instant 65-100 Tea, iced 47 Tea, brewed, imported brands (avg.) 60 Tea, brewed, U.S. brands (avg.) 40 Tea, instant 30 Tea, green 15 Hot cocoa 14 Coffee, Decaf, brewed 3-4 Coffee, Decaf, instant 2-3
I believe the confusion comes in due to the fact that tea has more caffeine before being brewed. But in the finished beverage, coffee has more caffeine.
