Caffeine and Tea

Caffeine and Tea

Tea is a regular drink for a lot of people and the tradition of drinking tea goes back millennia. Taken daily, it is one of the most delicious and healthiest beverages. When you look into the various teas grown around the world, you find that there are so many different types available and they have varying amounts of caffeine in them.  The 110mg of caffeine your average cup of coffee will get you awake in the morning and probably keep you awake during the day.  The typical amount of caffeine in tea can be affected by the blend of tea, the kind of tea and the steeping time.

The Strongest Teas

The measure of caffeine in a 230 ml or 8oz cup of tea is around 80mg.  There are many myths regarding tea and caffeine, for instance the amount of caffeine contained in teas of different colours.  Sometimes we are told that black teas have the highest levels while white teas are the lowest.  Actually, the strength in tea is largely to do with brewing, the kind of leaves or buds, and how it was grown.  The following teas reveal from highest to lowest based on the amount of caffeine:

  • Black Teas
  • White Teas
  • Green Teas
  • Herbal and Regular Blends
  • Herbal Teas (No Caffeine)

The Caffeine Process

The caffeine content in your tea, is largely affected by how your tea is grown, processed and packaged.  For instance, teas grown in the shade produce a lot more caffeine than those plants grown in the sun.  When the leaves have been finely chopped, sliced, or ground into a powder, the teas produced will have a much larger caffeine output than full natural leaves.  When leaves are cut or broken, this results in more caffeine being allowed to escape from the leaf.  When making White tea, we use newly grown leaves and buds and these contain more caffeine than older mature leaves.

Decaffeinated Teas

In nature, you will not find or locate an innate decaffeinated tea.  The Caffeine content of herbal and flower teas, is naturally low and can be completely absent.  Some drinkers can mix these herbs with black, white, or green teas reducing the caffeine amount.


Caffeine released with Brewing

When brewing tea and you need a reduced caffeine content, its best to steep the leaves for a shorter time than normal. So do not leave your tea leaves or tea bags soak for a long time.  Of course the opposite effect is gained when you desire an increased caffeine content by soaking the tea leaves for a longer time. Everyone has their favourite way to brew their tea, whether it is a strong caffeine morning boost, cooling iced tea or a soothing cup before bed.
