This collection of Decaffeinated teas are all processed by a water decaffeination process referred to as the "Swiss Water Method". This method removes the caffeine by soaking the tea in hot water for a period of time. Then the resulting brew is passed through a carbon filter for caffeine removal. The liquid is then reintroduced to the tea for the reabsorption of flavors and oils. Free customized sample and disposable tea filter included with every order.
