The process Decaffeination is the act of removing harmful caffeine from coffee beans, tea leaves, cocoa, and other caffeine-containing materials. While the caffeine free soft drinks are generally referred to as decaffeinated, some are better renamed uncaffeinated, will prepared without adding caffeine during production.
Despite of removal of harmful caffeine, many decaffeinated drinks still have around 2 to 3% of the original caffeine remaining in them.In that case of coffee beans, different methods can be used. The main process to decaffeinate tea is usually performed on unroasted or green coffee beans, and will starts with steaming of the beans. The beans are then rinsed with a solvent which extracts the harmful caffeine while leaving the other essential chemicals in the coffee beans. The main process is to repeated anywhere from 9 to 13 times until it either meets the international standard of having removed 96% of the harmful caffeine in the beans or the EU standard of having the beans 99.9% caffeine-free. Coffee beans contains over 500 chemicals important to the aroma and taste of the final drink, it is then therefore challenging to remove only caffeine while leaving the other useful chemicals at their original concentrations.
There are many ways to decaffeinate tea commercially and coffee in that case and some of those may use chemicals.

But make sure that you heat at least an extra 1/2 cup of water for this process, because you will need your entire water heater at once.
This useful method will works best with the loose leaf tea, as it is generally stronger in flavor than the bagged tea, however you can try it with either and just make some adjustments in quantities and times if needed. To decaffeinates tea by washing the caffeine off pour the heated water over the tea. Some may call for using a full cup of water, and others, only enough water to wet the tea. Most of them prefer enough water to cover the tea or bag, like about 1/4 – 1/2 cup.
