To better assist you with your tea choice here is the list that compares each tea type by how much caffeine the contain
If you’re like most adults, caffeine is a part of your daily routine. But do you know the caffeine content of your favorite drink? You may want to take a look at just how much caffeine you get in a typical day, especially if you’re bothered by headaches, restlessness or anxiety. If your caffeine habit total more than 500 milligrams a day, you may want to consider cutting back.
With the growing popularity of energy drinks, many parents have become concerned about how much caffeine their kids are getting. The American Academy of Pediatrics recommends that adolescents get no more than 100 mg of caffeine a day. Younger children shouldn't drink caffeinated beverages on a regular basis.
Because of various factors such as roasting and grinding as well as brewing time. The caffeine content of a tea also is affected by how long it’s brewed.

Caffeine levels are often reported in terms of mg per 8 oz cup, but people seldom drink only 8 oz of tea or coffee. Trying to relate reported caffeine to actual personal consumption doesn’t always give an accurate comparison. Why?
If an 8 oz cup of brewed coffee contains 150 mg of caffeine, a 16 oz cup of coffee will have 300 mg Similarly, when you drink an 8 oz cup of tea served from a brewed pot of tea, doubling the serving size to 16 oz results in double the caffeine.
But steeping tea in a mug is different. If you were to brew of mug of tea using 8 oz of water and one tea bug, the total caffeine could be around 40 mg. If you were to brew a larger mug of tea using 16 oz water and one tea bag, the total caffeine would not be double. It would still be only around 40 mg!
