Does green tea have caffeine?

Answer 1

Contrary to popular belief, green tea can have as much caffeine as black tea. The higher the quality of green tea, the more the caffeine.

You can't tell how much caffeine tea has from its colour. The finest Japanese green tea - Gyokuro - contains more caffeine than the black Lapsang Souchong.

High grade green tea is made from bud and the first two or three leaves. These tender shoots are the sweetest and tastiest. They also have the most caffeine.

Many experts advise that 30 to 45 seconds of hot washing would remove 80% of the caffeine. A 1996 study conducted by Auburn University dispelled this myth.

The first 5 minutes infusion soaks up 70% of caffeine. Subsequent infusions have much less caffeine.

If you are drinking teabags, don’t worry. There is little caffeine. But quality is correspondingly poor.

Hope it helps.

Answer 2

Caffeine was first discovered in tea in 1827, and was named theine. It was later found in mate and various other plants. Eventually it was shown that the theine of tea was identical with the caffeine of coffee, and the term theine was then dropped.
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.

So yes green tea is caffenated, but not nearly as much as a cup of coffee

Answer 3
