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