But cold water will also pull the caffeine out of the leaves, and after an hour most of the caffeine in the leaves will have seeped out into the water. Keep in mind that when you brew the tea in hot water, most of the caffeine will have left the leaves after the first steep. That process is analogous to how coffee is decaffeinated. About 40 mg per cup seems about right. Hot water has more energy, and will be more effective in helping the caffeine escape the tea leaves.
