Does tea or coffee have more caffeine?

Question

Which has more caffeine, coffee or tea?

Answer 1

Coffee

Answer 2

Coffee has more caffeine than tea.

Coffee 150 ml (5 oz) 60-150 mg. of caffeine
Coffee, decaf 150 ml (5 oz) 2-5 mg. of caffeine
Tea 150 ml (5 oz) 40-80 mg. of caffeine

Tea:
Caffeine content is also affected by the length of the infusion in water. Black tea infused for 5 minutes yields 40-100 milligrams, whereas a 3-minute infusion produces 20-40 milligrams, or half as much. Twenty cups of green tea yield 240 milligrams, or about 12 milligrams per cup.

In massive doses, caffeine is lethal. A fatal dose of caffeine has been calculated to be more than 10 grams (about 170 mg/kg body weight) - this is the same as drinking 80 to 100 cups of coffee in rapid succession - not an easy thing to do.

Caffeine enters the bloodstream through the stomach and small intestine and can have its effects as soon as 15 minutes after it is consumed. Once in the body, caffeine will stay around for hours: it takes about 6 hours for one half of the caffeine to be eliminated.

Answer 3

While coffee and tea are both sources of caffeine, the amounts of caffeine in any single serving of these beverages varies significantly. An average serving of coffee contains the most caffeine, yet the same serving size of tea provides only 1/2 to 1/3 as much.(Ref.: Caffeine by The Institute of Food Technologists' Expert Panel on Food Safety & Nutrition.) One of the more confusing aspects of caffeine content is the fact that coffee contains less caffeine than tea when measured in its dry form. The caffeine content of a prepared cup of coffee is significantly higher than the caffeine content of a prepared cup of tea.
