Caffeine occurs naturally in tea. A mild stimulant, it accounts for tea’s reputation as a beverage that clears the mind and lifts the spirit.
The more oxidized the tea – as in black tea – the greater its caffeine content, as demonstrated in the caffeine chart below. Green tea and 100% White Tea, which are not oxidized, have less caffeine per cup than black tea. In between we have oolong tea, which is semi-oxidized and has about half as much caffeine as black tea.
Something Interesting to Consider…
The smaller the leaf, the stronger the extraction of caffeine. Using comparable amounts and steeping times, a tea bag filled with cut leaves will release more caffeine per cup than full-leaf tea.
