Question

Does green tea have the same amount of caffeine as black tea?

Answer 1

The caffeine content varies by the amount of tea used and the length of time the leaves are infused.

Percentage of caffeine in:

Coffee- 0.05%

Black tea- 0.05%

Gyokuro- 0.02%

Sencha- 0.015%

Hoji cha- 0.008%

Genmai cha- 0.008%

Green Tea has four important constituents that all work together, caffeine, tannin, essential oils and vitamins. Many people may be surprised to hear that caffeine can actually be beneficial when taken in tea as it works slightly differently from the caffeine in coffee. The good news is caffeine in tea can stimulate the circulation and metabolism via the central nervous system.

The tannin in the Green Tea works alongside the caffeine, having a relaxing and stabilising effect. This means the caffeine is absorbed more slowly and prevents that "caffeine shock" we all know too well from coffee.

"There is a way of naturally removing caffeine and preserving the health benefits. Steep the tea for 45 seconds in hot water and then pour off the liquid. Next, add more hot water and steep as you normally would to brew a cup of that tea. Up to 80 percent of the caffeine is released in the first infusion of water so only minimal amounts will remain when you add water the second time. This method eliminates very little of the tea’s flavor and aroma."
