Every time you steep tea, caffeine is removed. The question is, how much tea is left after a second and third steeping? Is it true that you can rinse tea leaves to remove most of the caffeine?
Traditional Method for Removing Caffeine from Tea
- Steep tea for 30 Seconds in hot water
- Dump water
- Resteep tea for desired time
Now 80% of the caffeine is removed, right? Think again… According to a study by Dr. Bruce Branan, Professor of Chemistry at Asbury College (Wilmore, KY), it takes a three-minute infusion just to remove 46-70% of the caffeine from a cup of tea.
Another item of interest, a Chinese white tea ranked #2 in caffeine content, just under an Assam black tea, suggesting that oxidation doesn’t affect caffeine levels in tea.
