Caffeine occurs naturally in tea and coffee. It is a crystalline compound that is a mild stimulant of the central nervous system. The amount of caffeine in tea varies due to conditions where and how the tea plant (Camellia Sinensis) is grown, such as seasons when the plant is harvested, soil conditions, quality of water and growing temperature, to name a few. 

These values are for guidance only and they might vary depending on the amount of tea brewed in the tea bag, country of origin of the teas, and steep time. The longer  the steep time for tea, the stronger the extraction of caffeine.  Black tea is typically steeped for 5 minutes, Green tea is typically steeped for 2 minutes and White tea 1 minute. Additionally, the cup size or the amount of water does not affect the caffeine content.

Herbals like Peppermint and Camomile are naturally caffeine free because they do not come from the tea plant (Camellia Sinensis). 

No, it is not possible to remove 100% of the caffeine from the tea plant. Decaffeinated teas contain residual amounts of caffeine, about 2mg per 200ml cup.

Twinings teas are decaffeinated using the ethyl acetate method, which is one of the most popular ways to decaffeinate coffee and tea. After the tea leaves are moistened with water or steam, the process selectively absorbs caffeine and removes it from the tea. Afterward, ethyl acetate is removed, and the leaves dried. Ethyl acetate is an organic compound that is found in tea, coffee, and fruit, and provides for a safe and effective decaffeination method.
