How Much Caffeine is in Tea?

It's firstly important to clearly define Tea as anything belonging to the Camellia Sinensis family. If you take that plant and process it as a white, green, oolong, puerh, black tea then they all have caffeine. Things in the botanical world such as chamomile flowers, hibiscus, juniper berries etc are NOT a tea and as such do not contain caffeine.

The caffeine in tea acts differently to the caffeine in coffee. Tea has a powerful combination of caffeine and theanine which act together slow-down the absorption of caffeine. As a result, the onset of that 'caffeine kick' is much more gradual than coffee however the effects can last up to 10 hours. The L Theanine alongside the coffee is the reason drinking tea won’t result in the quick buzz and drop down feeling.

If you want to reduce the amount of caffeine you get from your tea here are 3 easy things you could do:

  1. Switch from tea to tisane. Tisanes are herbal infusions like rooibos or mint and contain no caffeine.
  2. Try a half minute initial steep and then pour the water out and re-steep (most caffeine is extracted in the first half minute)
  3. Use cooler water (using teas that steep at lower temperatures like white, oolong and greens are good choices)

Happy Tea Drinking!
