Easy Decaffeination
Need a way to decaffeinate your tea in a pinch, or have a favorite tea you't get in a decaffeinated version? The majority of tea's caffeine is released in the first 45 to 60 seconds of steeping. Knowing this, you can collect and remove much of the caffeine contained in most tea by using the following method. Steep the normal quantity of tea in a small amount of water (just enough to cover the leaves) heated to the appropriate temperature for the tea being brewed. Steep for no more than a minute, then remove the leaves and discard the water. Once this is done, re-steep the same tea leaves in a fresh cup of water for the customary amount of time, and you've made yourself a significantly decaffeinated cup of tea! This method will not remove the caffeine entirely, but could take out as much as 80%.

Keep in mind that small amounts of caffeine remain in tea decaffeinated by any method - only naturally caffeine-free herbal and fruit infusions lack it completely. It is also worth noting that the method described above may somewhat diminish the flavor and aroma of your tea.
