Coffee

There are three methods by which caffeine is extracted from coffee, the first two using chemicals that are poisonous in high doses.

The third method is done with plain water. La Brûlerie in Auray sells decaffeinated coffee made by this method ; organic stores should also do the same.

Tea

Caffeine and theine are known for their arousing effects. It is the same molecule, however, the arousal effects of tea are noticeably different from those of coffee.

To dehine your traditional tea, just let it steep for about 30 seconds, then throw in this water, then infuse it again. Indeed, the longer the infusion, the richer the tea will be in theine. This process should thus eliminate more than half of the theine, while retaining the flavors of your tea.

The caffeine / theine difference ?

The oxidized polyphenols contained in tea bind the effect of theine. This means that the theine is released into the bloodstream over a period of 6 to 8 hours and in a uniform manner.

The caffeine will be released quickly, producing a peak in intensity that will immediately fall over a period of 2 to 3 hours.
